Some of the features like MSM_GIC_SHOW_IRQ are using ARM_GIC
flag. So select this even for gic-v3 target on 32-bit.
This will also make it consistent with arm64 where ARM_GIC
is selected along with gic-v3.

The peripheral_mem carveout currently contains three separate images.
If these images are dynamically unloaded and reloaded in the wrong
order they could fragment the memory such that not all images would
fit.
Break apart the peripheral_mem into separate carveouts for each PIL
image to avoid the possibility of fragmentation.

commit d825c06bfe8b885b797f917ad47365d0e9c21fbb upstream.
When calculate_cpu_foreign_map() recalculates the cpu_foreign_map
cpumask it uses the local variable temp_foreign_map without initialising
it to zero. Since the calculation only ever sets bits in this cpumask
any existing bits at that memory location will remain set and find their
way into cpu_foreign_map too. This could potentially lead to cache
operations suboptimally doing smp calls to multiple VPEs in the same
core, even though the VPEs share primary caches.
Therefore initialise temp_foreign_map using cpumask_clear() before use.

commit 7a50e4688dabb8005df39b2b992d76629b8af8aa upstream.
The MIPS_GIC_IPI should only be selected when MIPS_GIC is also
selected, otherwise it results in a compile error. smp-gic.c uses some
functions from include/linux/irqchip/mips-gic.h like
plat_ipi_call_int_xlate() which are only added to the header file when
MIPS_GIC is set. The Lantiq SoC does not use the GIC, but supports SMP.
The calls top the functions from smp-gic.c are already protected by
some #ifdefs
The first part of this was introduced in commit 72e20142b2bf ("MIPS:
Move GIC IPI functions out of smp-cmp.c")

commit c88c5d43732a0356f99e5e4d1ad62ab1ea516b81 upstream.
The recently added OPAL API call, OPAL_CONSOLE_FLUSH, originally took no
parameters and returned nothing. The call was updated to accept the
terminal number to flush, and returned various values depending on the
state of the output buffer.
The prototype has been updated and its usage in the OPAL kmsg dumper has
been modified to support its new behaviour as an incremental flush.

commit affddff69c55eb68969448f35f59054a370bc7c1 upstream.
On BMC machines, console output is controlled by the OPAL firmware and is
only flushed when its pollers are called. When the kernel is in a panic
state, it no longer calls these pollers and thus console output does not
completely flush, causing some output from the panic to be lost.
Output is only actually lost when the kernel is configured to not power off
or reboot after panic (i.e. CONFIG_PANIC_TIMEOUT is set to 0) since OPAL
flushes the console buffer as part of its power down routines. Before this
patch, however, only partial output would be printed during the timeout wait.
This patch adds a new kmsg_dumper which gets called at panic time to ensure
panic output is not lost. It accomplishes this by calling OPAL_CONSOLE_FLUSH
in the OPAL API, and if that is not available, the pollers are called enough
times to (hopefully) completely flush the buffer.
The flushing mechanism will only affect output printed at and before the
kmsg_dump call in kernel/panic.c:panic(). As such, the "end Kernel panic"
message may still be truncated as follows:

This functionality is implemented as a kmsg_dumper as it seems to be the
most sensible way to introduce platform-specific functionality to the
panic function.

Since binutils 2.26 BFD is doing suffix merging on STRTAB sections. But
dedotify modifies the symbol names in place, which can also modify
unrelated symbols with a name that matches a suffix of a dotted name. To
remove the leading dot of a symbol name we can just increment the pointer
into the STRTAB section instead.
Backport to all stables to avoid breakage when people update their
binutils - mpe.

commit 3446c13b268af86391d06611327006b059b8bab1 upstream.
The fork of a process with four page table levels is broken since
git commit 6252d702c5311ce9 "[S390] dynamic page tables."
All new mm contexts are created with three page table levels and
an asce limit of 4TB. If the parent has four levels dup_mmap will
add vmas to the new context which are outside of the asce limit.
The subsequent call to copy_page_range will walk the three level
page table structure of the new process with non-zero pgd and pud
indexes. This leads to memory clobbers as the pgd_index *and* the
pud_index is added to the mm->pgd pointer without a pgd_deref
in between.
The init_new_context() function is selecting the number of page
table levels for a new context. The function is used by mm_init()
which in turn is called by dup_mm() and mm_alloc(). These two are
used by fork() and exec(). The init_new_context() function can
distinguish the two cases by looking at mm->context.asce_limit,
for fork() the mm struct has been copied and the number of page
table levels may not change. For exec() the mm_alloc() function
set the new mm structure to zero, in this case a three-level page
table is created as the temporary stack space is located at
STACK_TOP_MAX = 4TB.
This fixes CVE-2016-2143.

commit 5f0b819995e172f48fdcd91335a2126ba7d9deae upstream.
KVM has special logic to handle pages with pte.u=1 and pte.w=0 when
CR0.WP=1. These pages' SPTEs flip continuously between two states:
U=1/W=0 (user and supervisor reads allowed, supervisor writes not allowed)
and U=0/W=1 (supervisor reads and writes allowed, user writes not allowed).
When SMEP is in effect, however, U=0 will enable kernel execution of
this page. To avoid this, KVM also sets NX=1 in the shadow PTE together
with U=0, making the two states U=1/W=0/NX=gpte.NX and U=0/W=1/NX=1.
When guest EFER has the NX bit cleared, the reserved bit check thinks
that the latter state is invalid; teach it that the smep_andnot_wp case
will also use the NX bit of SPTEs.

commit 844a5fe219cf472060315971e15cbf97674a3324 upstream.
Yes, all of these are needed. :) This is admittedly a bit odd, but
kvm-unit-tests access.flat tests this if you run it with "-cpu host"
and of course ept=0.
KVM runs the guest with CR0.WP=1, so it must handle supervisor writes
specially when pte.u=1/pte.w=0/CR0.WP=0. Such writes cause a fault
when U=1 and W=0 in the SPTE, but they must succeed because CR0.WP=0.
When KVM gets the fault, it sets U=0 and W=1 in the shadow PTE and
restarts execution. This will still cause a user write to fault, while
supervisor writes will succeed. User reads will fault spuriously now,
and KVM will then flip U and W again in the SPTE (U=1, W=0). User reads
will be enabled and supervisor writes disabled, going back to the
originary situation where supervisor writes fault spuriously.
When SMEP is in effect, however, U=0 will enable kernel execution of
this page. To avoid this, KVM also sets NX=1 in the shadow PTE together
with U=0. If the guest has not enabled NX, the result is a continuous
stream of page faults due to the NX bit being reserved.
The fix is to force EFER.NX=1 even if the CPU is taking care of the EFER
switch. (All machines with SMEP have the CPU_LOAD_IA32_EFER vm-entry
control, so they do not use user-return notifiers for EFER---if they did,
EFER.NX would be forced to the same value as the host).
There is another bug in the reserved bit check, which I've split to a
separate patch for easier application to stable kernels.

commit ccec44563b18a0ce90e2d4f332784b3cb25c8e9c upstream.
Thomas Huth discovered that a guest could cause a hard hang of a
host CPU by setting the Instruction Authority Mask Register (IAMR)
to a suitable value. It turns out that this is because when the
code was added to context-switch the new special-purpose registers
(SPRs) that were added in POWER8, we forgot to add code to ensure
that they were restored to a sane value on guest exit.
This adds code to set those registers where a bad value could
compromise the execution of the host kernel to a suitable neutral
value on guest exit.

commit 9522b37f5a8c7bfabe46eecadf2e130f1103f337 upstream.
With MACHINE_HAS_VX, we convert the floating point registers from the
vector registeres when storing the status. For other VCPUs, these are
stored to vcpu->run->s.regs.vrs, but we are using current->thread.fpu.vxrs,
which resolves to the currently loaded VCPU.
So kvm_s390_store_status_unloaded() currently writes the wrong floating
point registers (converted from the vector registers) when called from
another VCPU on a z13.
This is only the case for old user space not handling SIGP STORE STATUS and
SIGP STOP AND STORE STATUS, but relying on the kernel implementation. All
other calls come from the loaded VCPU via kvm_s390_store_status().

commit 7099e2e1f4d9051f31bbfa5803adf954bb5d76ef upstream.
Linux guests on Haswell (and also SandyBridge and Broadwell, at least)
would crash if you decided to run a host command that uses PEBS, like
perf record -e 'cpu/mem-stores/pp' -a
This happens because KVM is using VMX MSR switching to disable PEBS, but
SDM [2015-12] 18.4.4.4 Re-configuring PEBS Facilities explains why it
isn't safe:
When software needs to reconfigure PEBS facilities, it should allow a
quiescent period between stopping the prior event counting and setting
up a new PEBS event. The quiescent period is to allow any latent
residual PEBS records to complete its capture at their previously
specified buffer address (provided by IA32_DS_AREA).
There might not be a quiescent period after the MSR switch, so a CPU
ends up using host's MSR_IA32_DS_AREA to access an area in guest's
memory. (Or MSR switching is just buggy on some models.)
The guest can learn something about the host this way:
If the guest doesn't map address pointed by MSR_IA32_DS_AREA, it results
in #PF where we leak host's MSR_IA32_DS_AREA through CR2.
After that, a malicious guest can map and configure memory where
MSR_IA32_DS_AREA is pointing and can therefore get an output from
host's tracing.
This is not a critical leak as the host must initiate with PEBS tracing
and I have not been able to get a record from more than one instruction
before vmentry in vmx_vcpu_run() (that place has most registers already
overwritten with guest's).
We could disable PEBS just few instructions before vmentry, but
disabling it earlier shouldn't affect host tracing too much.
We also don't need to switch MSR_IA32_PEBS_ENABLE on VMENTRY, but that
optimization isn't worth its code, IMO.
(If you are implementing PEBS for guests, be sure to handle the case
where both host and guest enable PEBS, because this patch doesn't.)

commit 0f514e690740e54815441a87708c3326f8aa8709 upstream.
Errata id: i877
Description:
------------
The RGMII 1000 Mbps Transmit timing is based on the output clock
(rgmiin_txc) being driven relative to the rising edge of an internal
clock and the output control/data (rgmiin_txctl/txd) being driven relative
to the falling edge of an internal clock source. If the internal clock
source is allowed to be static low (i.e., disabled) for an extended period
of time then when the clock is actually enabled the timing delta between
the rising edge and falling edge can change over the lifetime of the
device. This can result in the device switching characteristics degrading
over time, and eventually failing to meet the Data Manual Delay Time/Skew
specs.
To maintain RGMII 1000 Mbps IO Timings, SW should minimize the
duration that the Ethernet internal clock source is disabled. Note that
the device reset state for the Ethernet clock is "disabled".
Other RGMII modes (10 Mbps, 100Mbps) are not affected
Workaround:
-----------
If the SoC Ethernet interface(s) are used in RGMII mode at 1000 Mbps,
SW should minimize the time the Ethernet internal clock source is disabled
to a maximum of 200 hours in a device life cycle. This is done by enabling
the clock as early as possible in IPL (QNX) or SPL/u-boot (Linux/Android)
by setting the register CM_GMAC_CLKSTCTRL[1:0]CLKTRCTRL = 0x2:SW_WKUP.
So, do not allow to gate the cpsw clocks using ti,no-idle property in
cpsw node assuming 1000 Mbps is being used all the time. If someone does
not need 1000 Mbps and wants to gate clocks to cpsw, this property needs
to be deleted in their respective board files.

commit d7d5a43c0d16760f25d892bf9329848167a8b8a4 upstream.
When the Crypto SRAM mappings were added to the Device Tree files
describing the Armada XP boards in commit c466d997bb16 ("ARM: mvebu:
define crypto SRAM ranges for all armada-xp boards"), the fact that
those mappings were overlaping with the PCIe memory aperture was
overlooked. Due to this, we currently have for all Armada XP platforms
a situation that looks like this:
Memory mapping on Armada XP boards with internal registers at
0xf1000000:
- 0x00000000 -> 0xf0000000 3.75G RAM
- 0xf0000000 -> 0xf1000000 16M NOR flashes (AXP GP / AXP DB)
- 0xf1000000 -> 0xf1100000 1M internal registers
- 0xf8000000 -> 0xffe0000 126M PCIe memory aperture
- 0xf8100000 -> 0xf8110000 64KB Crypto SRAM #0 => OVERLAPS WITH PCIE !
- 0xf8110000 -> 0xf8120000 64KB Crypto SRAM #1 => OVERLAPS WITH PCIE !
- 0xffe00000 -> 0xfff00000 1M PCIe I/O aperture
- 0xfff0000 -> 0xffffffff 1M BootROM
The overlap means that when PCIe devices are added, depending on their
memory window needs, they might or might not be mapped into the
physical address space. Indeed, they will not be mapped if the area
allocated in the PCIe memory aperture by the PCI core overlaps with
one of the Crypto SRAM. Typically, a Intel IGB PCIe NIC that needs 8MB
of PCIe memory will see its PCIe memory window allocated from
0xf80000000 for 8MB, which overlaps with the Crypto SRAM windows. Due
to this, the PCIe window is not created, and any attempt to access the
PCIe window makes the kernel explode:
[ 3.302213] igb: Copyright (c) 2007-2014 Intel Corporation.
[ 3.307841] pci 0000:00:09.0: enabling device (0140 -> 0143)
[ 3.313539] mvebu_mbus: cannot add window '4:f8', conflicts with another window
[ 3.320870] mvebu-pcie soc:pcie-controller: Could not create MBus window at [mem 0xf8000000-0xf87fffff]: -22
[ 3.330811] Unhandled fault: external abort on non-linefetch (0x1008) at 0xf08c0018
This problem does not occur on Armada 370 boards, because we use the
following memory mapping (for boards that have internal registers at
0xf1000000):
- 0x00000000 -> 0xf0000000 3.75G RAM
- 0xf0000000 -> 0xf1000000 16M NOR flashes (AXP GP / AXP DB)
- 0xf1000000 -> 0xf1100000 1M internal registers
- 0xf1100000 -> 0xf1110000 64KB Crypto SRAM #0 => OK !
- 0xf8000000 -> 0xffe0000 126M PCIe memory
- 0xffe00000 -> 0xfff00000 1M PCIe I/O
- 0xfff0000 -> 0xffffffff 1M BootROM
Obviously, the solution is to align the location of the Crypto SRAM
mappings of Armada XP to be similar with the ones on Armada 370, i.e
have them between the "internal registers" area and the beginning of
the PCIe aperture.
However, we have a special case with the OpenBlocks AX3-4 platform,
which has a 128 MB NOR flash. Currently, this NOR flash is mapped from
0xf0000000 to 0xf8000000. This is possible because on OpenBlocks
AX3-4, the internal registers are not at 0xf1000000. And this explains
why the Crypto SRAM mappings were not configured at the same place on
Armada XP.
Hence, the solution is two-fold:
(1) Move the NOR flash mapping on Armada XP OpenBlocks AX3-4 from
0xe8000000 to 0xf0000000. This frees the 0xf0000000 ->
0xf80000000 space.
(2) Move the Crypto SRAM mappings on Armada XP to be similar to
Armada 370 (except of course that Armada XP has two Crypto SRAM
and not one).
After this patch, the memory mapping on Armada XP boards with
registers at 0xf1 is:
- 0x00000000 -> 0xf0000000 3.75G RAM
- 0xf0000000 -> 0xf1000000 16M NOR flashes (AXP GP / AXP DB)
- 0xf1000000 -> 0xf1100000 1M internal registers
- 0xf1100000 -> 0xf1110000 64KB Crypto SRAM #0
- 0xf1110000 -> 0xf1120000 64KB Crypto SRAM #1
- 0xf8000000 -> 0xffe0000 126M PCIe memory
- 0xffe00000 -> 0xfff00000 1M PCIe I/O
- 0xfff0000 -> 0xffffffff 1M BootROM
And the memory mapping for the special case of the OpenBlocks AX3-4
(internal registers at 0xd0000000, NOR of 128 MB):
- 0x00000000 -> 0xc0000000 3G RAM
- 0xd0000000 -> 0xd1000000 1M internal registers
- 0xe800000 -> 0xf0000000 128M NOR flash
- 0xf1100000 -> 0xf1110000 64KB Crypto SRAM #0
- 0xf1110000 -> 0xf1120000 64KB Crypto SRAM #1
- 0xf8000000 -> 0xffe0000 126M PCIe memory
- 0xffe00000 -> 0xfff00000 1M PCIe I/O
- 0xfff0000 -> 0xffffffff 1M BootROM

commit 36e5cd6b897e17d03008f81e075625d8e43e52d0 upstream.
Commit dfd55ad85e4a ("arm64: vmemmap: use virtual projection of linear
region") fixed an issue where the struct page array would overflow into the
adjacent virtual memory region if system RAM was placed so high up in
physical memory that its addresses were not representable in the build time
configured virtual address size.
However, the fix failed to take into account that the vmemmap region needs
to be relatively aligned with respect to the sparsemem section size, so that
a sequence of page structs corresponding with a sparsemem section in the
linear region appears naturally aligned in the vmemmap region.
So round up vmemmap to sparsemem section size. Since this essentially moves
the projection of the linear region up in memory, also revert the reduction
of the size of the vmemmap region.

commit e723e3f7f9591b79e8c56b3d7c5a204a9c571b55 upstream.
Avoid sending a partially initialised `siginfo_t' structure along SIGFPE
signals issued from `do_ov' and `do_trap_or_bp', leading to information
leaking from the kernel stack.

commit 56fa81fc9a5445938f3aa2e63d15ab63dc938ad6 upstream.
In current scache init cache line_size is determined from
cpu config register, however if there there no scache
then mips_sc_probe_cm3 function populates a invalid line_size of 2.
The invalid line_size can cause a NULL pointer deference
during r4k_dma_cache_inv as r4k_blast_scache is populated
based on line_size. Scache line_size of 2 is invalid option in
r4k_blast_scache_setup.
This issue was faced during a MIPS I6400 based virtual platform bring up
where scache was not available in virtual platform model.

commit 92f9e179a702a6adbc11e2fedc76ecd6ffc9e3f7 upstream.
Pause/unpause graph tracing around do_suspend_lowlevel as it has
inconsistent call/return info after it jumps to the wakeup vector.
The graph trace buffer will otherwise become misaligned and
may eventually crash and hang on suspend.
To reproduce the issue and test the fix:
Run a function_graph trace over suspend/resume and set the graph
function to suspend_devices_and_enter. This consistently hangs the
system without this fix.

commit dfd55ad85e4a7fbaa82df12467515ac3c81e8a3e upstream.
Commit dd006da21646 ("arm64: mm: increase VA range of identity map") made
some changes to the memory mapping code to allow physical memory to reside
at an offset that exceeds the size of the virtual mapping.
However, since the size of the vmemmap area is proportional to the size of
the VA area, but it is populated relative to the physical space, we may
end up with the struct page array being mapped outside of the vmemmap
region. For instance, on my Seattle A0 box, I can see the following output
in the dmesg log.
vmemmap : 0xffffffbdc0000000 - 0xffffffbfc0000000 ( 8 GB maximum)
0xffffffbfc0000000 - 0xffffffbfd0000000 ( 256 MB actual)
We can fix this by deciding that the vmemmap region is not a projection of
the physical space, but of the virtual space above PAGE_OFFSET, i.e., the
linear region. This way, we are guaranteed that the vmemmap region is of
sufficient size, and we can even reduce the size by half.

commit 4cad67fca3fc952d6f2ed9e799621f07666a560f upstream.
Calling return copy_to_user(...) in an ioctl will not
do the right thing if there's a pagefault:
copy_to_user returns the number of bytes not copied
in this case.
Fix up kvm to do
return copy_to_user(...)) ? -EFAULT : 0;
everywhere.

commit 70e4da7a8ff62f2775337b705f45c804bb450454 upstream.
Commit 172b2386ed16 ("KVM: x86: fix missed hardware breakpoints",
2016-02-10) worked around a case where the debug registers are not loaded
correctly on preemption and on the first entry to KVM_RUN.
However, Xiao Guangrong pointed out that the root cause must be that
KVM_DEBUGREG_BP_ENABLED is not being set correctly. This can indeed
happen due to the lazy debug exit mechanism, which does not call
kvm_update_dr7. Fix it by replacing the existing loop (more or less
equivalent to kvm_update_dr0123) with calls to all the kvm_update_dr*
functions.

vmx.c writes the TSC_MULTIPLIER field in vmx_vcpu_load, but only when a
vcpu has migrated physical cpus. Record the last value written and
update in vmx_vcpu_load on any change, otherwise a cpu migration must
occur for TSC frequency scaling to take effect.
