This reverts commit 91fa97e1e5c001d52f6c993d37be08d1e84f47b7.
This patch is no longer valid. There are no users for this status irq and
callback in android-4.x. The Qcom platform (mach-msm/qsd8x50, HTC Dream..)
and SDCC controller (msm_sdcc) using this status IRQ and callback are
dropped from mainline sometime back.

Allows FUSE to report to inotify that it is acting
as a layered filesystem. The userspace component
returns a string representing the location of the
underlying file. If the string cannot be resolved
into a path, the top level path is returned instead.

Attempts to build sdcardfs as module fail with
fs/sdcardfs/lookup.c: In function '__sdcardfs_lookup':
fs/sdcardfs/lookup.c:243:5: error: 'LOOKUP_CASE_INSENSITIVE' undeclared
This occurs because the define is enclosed with #ifdef
CONFIG_SDCARD_FS_CI_SEARCH. If SDCARD_FS_CI_SEARCH is configured to be
built as module, this does not work. Alternatives would be to use #if
IS_ENABLED(CONFIG_SDCARD_FS_CI_SEARCH), or to declare SDCARD_FS_CI_SEARCH
as bool, but that does not work because the define is used unconditionally
in the source.
Note that LOOKUP_CASE_INSENSITIVE is only set but not evaluated in the
current source code, so setting the flag has no real effect.

Inotify does not currently know when a filesystem
is acting as a wrapper around another fs. This means
that inotify watchers will miss any modifications to
the base file, as well as any made in a separate
stacked fs that points to the same file.
d_canonical_path solves this problem by allowing the fs
to map a dentry to a path in the lower fs. Inotify
can use it to find the appropriate place to watch to
be informed of all changes to a file.

(cherry picked from commit https://lkml.org/lkml/2016/2/4/831)
d07e22597d1d355 ("mm: mmap: add new /proc tunable for mmap_base ASLR")
added the ability to choose from a range of values to use for entropy
count in generating the random offset to the mmap_base address. The
maximum value on this range was set to 32 bits for 64-bit x86 systems, but
this value could be increased further, requiring more than the 32 bits of
randomness provided by get_random_int(), as is already possible for arm64.
Add a new function: get_random_long() which more naturally fits with the
mmap usage of get_random_int() but operates exactly the same as
get_random_int().
Also, fix the shifting constant in mmap_rnd() to be an unsigned long so
that values greater than 31 bits generate an appropriate mask without
overflow. This is especially important on x86, as its shift instruction
uses a 5-bit mask for the shift operand, which meant that any value for
mmap_rnd_bits over 31 acts as a no-op and effectively disables mmap_base
randomization.
Finally, replace calls to get_random_int() with get_random_long() where
appropriate.

The API to log the suspend reason was introduced with commit 57caa2ad5ce3
("power: Adds functionality to log the last suspend abort reason.").
It is called from functions enabled with PM_SLEEP and from functions
enabled with SUSPEND, but only available if SUSPEND is enabled.
This can result in build failures such as the following if PM_SLEEP
is enabled, but SUSPEND is not.
kernel/built-in.o: In function `try_to_freeze_tasks':
process.c:(.text+0x30928): undefined reference to `log_suspend_abort_reason'
drivers/built-in.o: In function `syscore_suspend':

Commit 1af89c1ef3b6 ("Hack: net: PPPoPNS and PPPoLAC build fixes for 4.1")
fixed the build for PPPoPNS and PPPoLAC by re-introducing a field in
struct msghdr which was removed upstream. Re-introducing the field doesn't
get it used, so it is quite likely that the code never worked. Fix it up for
good.

Robust context attempts to perform a rendering that takes too long
whether due to an infinite loop in a shader or even just a rendering
operation that takes too long on the given hardware. This type of
attempts can result into GPU faults. Robust context expect driver
to replay IB instead skip IB and if it fails on replay context has
to be invalidated.
KGSL_CONTEXT_INVALIDATE_ON_FAULT flag allows draw context to execute
only replay policy on GPU fault recovery instead of going to default
recovery policy. User space has to set this flag during the context
creation.

Add a check for cpu unbound deferrable timer expiry and raise
softirq for handling the expired timers so that the CPU can
process the cpu unbound deferrable times as early as possible
when a cpu tries to enter/exit idle loop.

Add Minidump support for clients to get minimum required data
at the time of system crash. The Minidump table resides in SMEM,
BOOT(SBL) will iterate the table entries and dumps out (to USB/Flash)
the data in address location.
Any client can register to this table with static or known addresses,
as currently Minidump doesn't support dumping of dynamic data structures.
To simplify post processing, we create an ELF header, where each entry in
the minidump table is a section in elf header.
If Memory dump table enabled, Dump all data entries registered with MDT.
Enable Minidump:

Currently the hotplug notifier calls cpu_pmu_enable_percpu_irq

Change the code to follow what was done in 3.18 including
tracking whether the PMU is active and the IRQ number in use.

Allow clients to specify the IOVA range for fastmap clients
via the DOMAIN_ATTR_GEOMETRY domain attribute.
Presently fastmap only allocates page tables for the IOVA
range specified during the create mapping call. However
clients may want to use IOVA addresses outside this range,
such as for their calls to iommu_map.
So allow clients to extend the available IOVA space by setting
the DOMAIN_ATTR_GEOMETRY domain attribute's
iommu_domain_geometry.aperture_start to
the new start address of the IOVA space and by setting
iommu_domain_geometry.aperture_end to the new end address of the
IOVA space.
The new IOVA space created by iommu_domain_geometry.aperture_start
and iommu_domain_geometry.aperture_end will be a superset of the
IOVA range which was created through the create mapping call.
The DOMAIN_ATTR_GEOMETRY domain attribute can only be set before
attaching.
Calls to set the DOMAIN_ATTR_GEOMETRY domain attribute can only
be used to extend the IOVA space, it cannot shrink the range.
Note that extending the IOVA range will not change the range of
IOVA addresses which will be available to the DMA APIs.

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.

Refactor the fs readpage/write tracepoints to move the
inode->path lookup outside the tracepoint code, and pass a pointer
to the path into the tracepoint code instead. This is necessary
because the tracepoint code runs non-preemptible. Thanks to
Trilok Soni for catching this in 4.4.

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.
