The commit '6b4f77 (mm: vmscan: invoke slab shrinkers from shrink_zone())'
fixed the invocation of shrinkers but resulted in lowmemorykiller shrinker
being called more. Reduce the number of lowmemorykiller shrinker
invocations by separating out the lowmemorykiller shrinker from
shrink_slab. This will make lowmemorykiller invoked only once for all zones
reclaimed in the direct reclaim path, and once for each zone in the kswap
path. As a consequence the eligible pages passed to shrink_slab_lmk is now
the reclaimable pages of all zones. Reducing the number of lowmemorykiller
invocations reduces the unnecessary time spent in lowmemorykiller and thus
contention or failures on lowmemorykiller's scan_mutex.

On SPARSEMEM systems page poisoning is enabled after buddy is up, because
of the dependency on page extension init. This causes the pages released
by free_all_bootmem not to be poisoned. This either delays or misses the
identification of some issues because the pages have to undergo another
cycle of alloc-free-alloc for any corruption to be detected.
Enable page poisoning early by getting rid of the PAGE_EXT_DEBUG_POISON
flag. Since all the free pages will now be poisoned, the flag need not be
verified before checking the poison during an alloc.

By default, page poisoning uses a poison value (0xaa) on free. If this
is changed to 0, the page is not only sanitized but zeroing on alloc
with __GFP_ZERO can be skipped as well. The tradeoff is that detecting
corruption from the poisoning is harder to detect. This feature also
cannot be used with hibernation since pages are not guaranteed to be
zeroed after hibernation.

Page poisoning is currently set up as a feature if architectures don't
have architecture debug page_alloc to allow unmapping of pages. It has
uses apart from that though. Clearing of the pages on free provides an
increase in security as it helps to limit the risk of information leaks.
Allow page poisoning to be enabled as a separate option independent of
kernel_map pages since the two features do separate work. Because of
how hiberanation is implemented, the checks on alloc cannot occur if
hibernation is enabled. The runtime alloc checks can also be enabled
with an option when !HIBERNATION.

Replace unsigned long with __u32 as 4 bytes is the length
of field where as unsigned long could be 8 bytes on 64 bit
machine. Also, replace short and char with u16 and u8
respectively for better readability.

BADD 3.0 devices support three types of topologies;
Basic I/P, Basic O/P, and BASIC I/P. Accordingly, various
units and terminals have to be parsed which are not
exposed by the device and host must be able to figure
out various class-specific descriptors based on the
profile ID of the device. This patch adds this logic
to build various units and terminals of the AudioControl
interface of a BADD device.

BADD(Basic Audio Device Definition) is a subset of UAC3
specifications. It defines standard profiles which provide
specific attributes of class descriptors. BADD audio device
provides profile id and BADD supporting host will infer
attributes from profile-id.
Currently USB Audio Host driver has support for UAC1
and UAC2 devices. To handle BADD 3.0 devices, AudioControl
and AudioStreaming Interfaces have to be properly parsed.
The Host has to derive all class-specific information based
on the profile ID that the device exposes. Add support for
parsing the AudioStreaming interfaces exposed by the device.

This message is currently really useless since it always prints a value
that comes from the printk() we just did, e.g.:
BUG: sleeping function called from invalid context at mm/slab.h:388
in_atomic(): 0, irqs_disabled(): 0, pid: 31996, name: trinity-c1
Preemption disabled at:[<ffffffff8119db33>] down_trylock+0x13/0x80
BUG: sleeping function called from invalid context at include/linux/freezer.h:56
in_atomic(): 0, irqs_disabled(): 0, pid: 31996, name: trinity-c1
Preemption disabled at:[<ffffffff811aaa37>] console_unlock+0x2f7/0x930
Here, both down_trylock() and console_unlock() is somewhere in the
printk() path.
We should save the value before calling printk() and use the saved value
instead. That immediately reveals the offending callsite:
BUG: sleeping function called from invalid context at mm/slab.h:388
in_atomic(): 0, irqs_disabled(): 0, pid: 14971, name: trinity-c2
Preemption disabled at:[<ffffffff819bcd46>] rhashtable_walk_start+0x46/0x150

Add support for HW_CURRENT_MAX property which returns maximum
input current that can be set for an adapter. This property will
be specifically used by parallel charger to cast an initial ICL
vote.

UHS-I SD cards support SDR104 mode which runs the SD card interface
clock upto 208 MHz. But we may see repeated CRC errors in SDR104
with some SDCC controllers. If this happens, this change would
reinit the card to lower speed (SDR50) hoping that CRC error
rate would reduce at lower clock speed (100MHz for SDR50).

On Certain chipsets, SDR104 mode might be unstable causing CRC error on
the interface. So we need a workaround which would skip printing register
dumps on CRC errors and also downgrade bus speed mode to SDR50/DDR50 in
case of continuous CRC errors. This patch adds "qcom,sdr104-wa" property
to enable this workaround if required.

is not being used anywhere. Also it is wrongly
being freed from mmc_remove_card and causing
"double kfree" related issues.
To handle this, remove unused cached_ext_csd variable.

In some cases the hpd call cannot be blocked. For example, in
case of framework restart, both display and audio HALs are not
available, so nobody will notify and unblock hpd call. Another
case is continuous splash in which unblank is delayed till the
first display kickoff, so hpd cannot blocking wait for such a
late notification.

commit 86ef58a4e35e8fa66afb5898cf6dec6a3bb29f67 upstream.
The interleave-set cookie is a sum that sanity checks the composition of
an interleave set has not changed from when the namespace was initially
created. The checksum is calculated by sorting the DIMMs by their
location in the interleave-set. The comparison for the sort must be
64-bit wide, not byte-by-byte as performed by memcmp() in the broken
case.
Fix the implementation to accept correct cookie values in addition to
the Linux "memcmp" order cookies, but only allow correct cookies to be
generated going forward. It does mean that namespaces created by
third-party-tooling, or created by newer kernels with this fix, will not
validate on older kernels. However, there are a couple mitigating
conditions:
1/ platforms with namespace-label capable NVDIMMs are not widely
available.
2/ interleave-sets with a single-dimm are by definition not affected
(nothing to sort). This covers the QEMU-KVM NVDIMM emulation case.
The cookie stored in the namespace label will be fixed by any write the
namespace label, the most straightforward way to achieve this is to
write to the "alt_name" attribute of a namespace in sysfs.

commit d24cdcd3e40a6825135498e11c20c7976b9bf545 upstream.
I ran into this compile warning, which is the result of BUG_ON(1)
not always leading to the compiler treating the code path as
unreachable:
include/linux/ceph/osdmap.h: In function 'ceph_can_shift_osds':
include/linux/ceph/osdmap.h:62:1: error: control reaches end of non-void function [-Werror=return-type]
Using BUG() here avoids the warning.

It is not sufficient to just check that the lock pids match when
granting a callback, we also need to ensure that we're granting
the callback on the right file.

commit aaa59306b0b7e0ca4ba92cc04c5db101cbb1c096 upstream.
