Due to Errata in ThunderX, HOST_IRQ_STAT should be
cleared before leaving the interrupt handler.
The patch attempts to satisfy the need.
Changes from V2:
- removed newfile
- code is now under CONFIG_ARM64
Changes from V1:
- Rebased on top of libata/for-4.6
- Moved ThunderX intr handler to new file
tj: Minor adjustments to comments.

The Parrot NMEA GPS Flight Recorder is a USB composite device
consisting of hub, flash storage, and cp210x usb to serial chip.
It is an accessory to the mass-produced Parrot AR Drone 2.
The device emits standard NMEA messages which make the it compatible
with NMEA compatible software. It was tested using gpsd version 3.11-3
as an NMEA interpreter and using the official Parrot Flight Recorder.

Games with ordering and barriers are way too brittle. Just
bump ->d_seq before and after updating ->d_inode and ->d_flags
type bits, so that verifying ->d_seq would guarantee they are
coherent.

HDSPM driver contains a code issuing zero-division potentially in

Add support for the HDMI PHY/PLL found in MSM8996/APQ8096.
Unlike the previous PHYs supported in the driver, this doesn't need
the powerup/powerdown ops. The PLL prepare/unprepare clock ops

Add a helper to initialize PLL in the PHY driver. HDMI PLLs are going to
have their own mmio base different from that of PHY.
For the clock code in hdmi_phy_8960.c, some changes were needed for it to
work with the updated register offsets. Create a copy of the updated clock
code in hdmi_pll_8960.c, instead of rewriting it in hdmi_phy_8960.c
itself. This removes the need to place CONFIG_COMMON_CLOCK checks all
around, makes the code more legible, and also removes some old checkpatch
warnings with the original code.
The older hdmi pll clock ops in hdmi_phy_8960.c will be removed later. The
driver will use these until the HDMI PHY/PLL register offsets aren't
considered as separate domains (i.e. their offsets start from 0).

Create a PHY device that represents the TX PHY and PLL parts of the HDMI
block.
This makes management of PHY specific resources (regulators and clocks)
much easier, and makes the PHY and PLL usable independently. It also
simplifies the core HDMI driver, which currently assigns phy ops among
many other things.
The PHY driver implementation done here is very similar to the PHY driver
we already have for DSI.
Keep the old hdmi_phy_funcs ops for now. The driver will use these until
the HDMI PHY/PLL register offsets aren't considered as separate
domains (i.e. their offsets start from 0).
The driver doesn't use the common PHY framework for now. This is because
it's hard to map our ops with the ops provided by the framework. The
bindings used for this is the generic phy bindings. So, this can be
adapted to the PHY framework in the future, if possible.

Make gpio allocation and usage iterative by parsing the gpios on a given
platform from a list. This gives us flexibility over what all gpios exist
for a platform, whether they are input or output, and what value they
should be set to.
In particular, this will make HDMI on 8x96 platforms easier to integrate
with the driver, as it doesn't have a HPD gpio input to them. Also, it
cleans things up a bit.
We still use the legacy gpio api here, as we might need to backport this
driver to downstream kernels.

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.

The target independent parts of the LLVM Lexer considers 'fault@function'
to be a single token representing the 'fault' symbol with a 'function'
modifier. However, this is not the case in the .type directive where
'function' refers to STT_FUNC from the ELF standard.
Although GAS accepts it, '.type symbol@function' is an undocumented form of
this directive. The documentation specifies a comma between the symbol and
'@function'.

This issue is caused by commit 02323db17e3a7 ("cifs: fix
cifs_uniqueid_to_ino_t not to ever return 0"), when BITS_PER_LONG
is 64 on s390x, the corresponding cifs_uniqueid_to_ino_t()
function will cast 64-bit fileid to 32-bit by using (ino_t)fileid,
because ino_t (typdefed __kernel_ino_t) is int type.
It's defined in arch/s390/include/uapi/asm/posix_types.h
#ifndef __s390x__
typedef unsigned long __kernel_ino_t;
...
#else /* __s390x__ */
typedef unsigned int __kernel_ino_t;
So the #ifdef condition is wrong for s390x, we can just still use
one cifs_uniqueid_to_ino_t() function with comparing sizeof(ino_t)
and sizeof(u64) to choose the correct execution accordingly.

When opening a file, SMB2_open() attempts to parse the lease state from the

X32 ABI takes the 64bit timespec, thus the timer user status ioctl becomes
incompatible with IA32. This results in NOTTY error when the ioctl is
issued.
Meanwhile, this struct in X32 is essentially identical with the one in
X86-64, so we can just bypassing to the existing code for this
specific compat ioctl.

X32 ABI uses the 64bit timespec in addition to 64bit alignment of

The X32 ABI takes the same alignment like x86-64, and this may result
in the incompatible struct size from ia32. Unfortunately, we hit this
in some control ABI: struct snd_ctl_elem_value differs between them
due to the position of 64bit variable array. This ends up with the
unknown ioctl (ENOTTY) error.
The fix is to add the compat entries for the new aligned struct.

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 vfio to do
return copy_to_user(...)) ?
-EFAULT : 0;
everywhere.

Pull ARM SoC fixes from Olof Johansson:
"We didn't have a batch last week, so this one is slightly larger.
None of them are scary though, a handful of fixes for small DT pieces,
replacing properties with newer conventions.
Highlights:
- N900 fix for setting system revision
- onenand init fix to avoid filesystem corruption
- Clock fix for audio on Beaglebone-x15
- Fixes on shmobile to deal with CONFIG_DEBUG_RODATA (default y in 4.6)
+ misc smaller stuff"

both do_last() and walk_component() risk picking a NULL inode out
of dentry about to become positive, *then* checking its flags and
seeing that it's not negative anymore and using (already stale by
then) value they'd fetched earlier. Usually ends up oopsing soon
after that...

... into returning a positive to path_openat(), which would interpret that
as "symlink had been encountered" and proceed to corrupt memory, etc.
It can only happen due to a bug in some ->open() instance or in some LSM
hook, etc., so we report any such event *and* make sure it doesn't trick
us into further unpleasantness.
