Remove "qcom,mdss-dsi-on-command" and "mdss-dsi-off command"
commands for boot up performance optimization.
The two commands are for native DSI panels without a bridge
chip. However,AUTO platform has adv7533 bridge chip,which
is controlled by I2C instead of the above two commands.
In addition,the two command will cause extra wait for about
210ms in dsi_panel_tx_cmd_set() for dsi_display_enbale().
This make drmAtomicCommit() in libdrm a little slower,
so total boot time will be longer.

Section mapping is good for TLB. But sometimes, when
system is low on physically continuous memory, this can
cause memory allocation failures. Add a fallback option to
allocate vmemmap pages from discontinuous pages.

This is a second and improved version of the patch previously released
in [3].
It builds on the work by Scott Branden [2] and, henceforth,
it needs to be applied on top of Scott's patches [2].
Comments are very welcome.
Changes from the original patchset and known issues:
- Compared to Scott's original patchset, this work adds the mapping of
the new hotplugged pages into the kernel page tables. This is done by
copying the old swapper_pg_dir over a new page, adding the new mappings,
and then switching to the newly built pg_dir (see `hotplug_paging` in
arch/arm64/mmu.c). There might be better ways to to this: suggestions
are more than welcome.
- The stub function for `arch_remove_memory` has been removed for now; we
are working in parallel on memory hot remove, and we plan to contribute
it as a separate patch.
- Corresponding Kconfig flags have been added;
- Note that this patch does not work when NUMA is enabled; in fact,
the function `memory_add_physaddr_to_nid` does not have an
implementation when the NUMA flag is on: this function is supposed to
return the nid the hotplugged memory should be associated with. However
it is not really clear to us yet what the semantics of this function
in the context of a NUMA system should be. A quick and dirty fix would
be to always attach to the first available NUMA node.
- In arch/arm64/mm/init.c `arch_add_memory`, we are doing a hack with the
nomap memory block flags to satisfy preconditions and postconditions of
`__add_pages` and postconditions of `arch_add_memory`. Compared to
memory hotplug implementation for other architectures, the "issue"
seems to be in the implemenation of `pfn_valid`. Suggestions on how
to cleanly avoid this hack are welcome.
This patchset can be tested by starting the kernel with the `mem=X` flag, where
X is less than the total available physical memory and has to be multiple of
MIN_MEMORY_BLOCK_SIZE. We also tested it on a customised version of QEMU
capable to emulate physical hotplug on arm64 platform.
To enable the feature the CONFIG_MEMORY_HOTPLUG compilation flag
needs to be set to true. Then, after memory is physically hotplugged,
the standard two steps to make it available (as also documented in
Documentation/memory-hotplug.txt) are:
(1) Notify memory hot-add
echo '0xYY000000' > /sys/devices/system/memory/probe
where 0xYY000000 is the first physical address of the new memory section.
(2) Online new memory block(s)
echo online > /sys/devices/system/memory/memoryXXX/state
-- or --
echo online_movable > /sys/devices/system/memory/memoryXXX/state
where XXX corresponds to the ids of newly added blocks.
Onlining can optionally be automatic at hot-add notification by enabling
the global flag:
echo online > /sys/devices/system/memory/auto_online_blocks
or by setting the corresponding config flag in the kernel build.
Again, any comment is highly appreciated.

This can be avoided if we disable tasha codec from dts.
Similarly sdm660-qrd has only tasha as codec.

commit 374b3bf8e8b519f61eb9775888074c6e46b3bf0c upstream.
As discussed on the debian-hppa list, double-wordcompare and exchange
operations fail on 32-bit kernels. Looking at the code, I realized that
the ",ma" completer does the wrong thing in the "ldw,ma 4(%r26), %r29"
instruction. This increments %r26 and causes the following store to
write to the wrong location.
Note by Helge Deller:
The patch applies cleanly to stable kernel series if this upstream
commit is merged in advance:

commit f4125cfdb3008363137f744c101e5d76ead760ba upstream.
There is no need to trash sr2 and sr3 in the Light-weight syscall (LWS). sr2
already points to kernel space (it's zero in userspace, otherwise syscalls
wouldn't work), and since the LWS code is executed in userspace, we can simply
ignore to preload sr3.

The linker routines that we rely on to produce a relocatable PIE binary
treat it as a shared ELF object in some ways, i.e., it emits symbol based
R_AARCH64_ABS64 relocations into the final binary since doing so would be
appropriate when linking a shared library that is subject to symbol
preemption. (This means that an executable can override certain symbols
that are exported by a shared library it is linked with, and that the
shared library *must* update all its internal references as well, and point
them to the version provided by the executable.)
Symbol preemption does not occur for OS hosted PIE executables, let alone
for vmlinux, and so we would prefer to get rid of these symbol based
relocations. This would allow us to simplify the relocation routines, and
to strip the .dynsym, .dynstr and .hash sections from the binary. (Note
that these are tiny, and are placed in the .init segment, but they clutter
up the vmlinux binary.)
Note that these R_AARCH64_ABS64 relocations are only emitted for absolute
references to symbols defined in the linker script, all other relocatable
quantities are covered by anonymous R_AARCH64_RELATIVE relocations that
simply list the offsets to all 64-bit values in the binary that need to be
fixed up based on the offset between the link time and run time addresses.
Fortunately, GNU ld has a -Bsymbolic option, which is intended for shared
libraries to allow them to ignore symbol preemption, and unconditionally
bind all internal symbol references to its own definitions. So set it for
our PIE binary as well, and get rid of the asoociated sections and the
relocation code that processes them.

Signed-off-by: Will Deacon <will.deacon@arm.com>
Note: This backport only adds -Bsymbolic to LDFLAGS_vmlinux, but doesn't
remove R_AARCH64_ABS64 relocation handling, because those changes depend
on later refactoring of the code that we don't need in android-4.4.

Commit a1d5ebaf8ccd ("arm64: big-endian: don't treat code as data when
copying sigret code") moved the 32-bit sigreturn trampoline code from
the aarch32_sigret_code array to kuser32.S. The commit removed the
array definition from signal32.c, but not its declaration in
signal32.h. Remove the leftover declaration.
