Even after disabling interrupts on the module, it could be possible
that irq handlers are still running. System hang is seen during
suspend path. It was found that, there were pending writes on the
HDA bus and clock was disabled by that time.
Above mentioned issue is fixed by clearing any pending irq handlers
before disabling clocks and returning from hda suspend.

The check for special (reserved) inode number checks in __ext4_iget()
was broken by commit 8a363970d1dc: ("ext4: avoid declaring fs
inconsistent due to invalid file handles"). This was caused by a
botched reversal of the sense of the flag now known as
EXT4_IGET_SPECIAL (when it was previously named EXT4_IGET_NORMAL).
Fix the logic appropriately.

Most changes here are to enable new drivers and platforms in the various
configs that affect them. Most of these have been covered and described
in the other branches, we mostly keep defconfig separate to avoid
conflicts between SoC/dt/driver updates that they otherwise would be
grouped with.
One thing worth mentioning here is that OMAP changes from using their
own UART driver, to 8250, for the multi_v7_defconfig shared config on
32-bit. This means that the console is now named ttyS* instead of ttyO*.
This change was already done for omap2_defconfig a while back, so most
users of these configs have either already updated, or can easily follow
the same patterns as they did at that time. This makes platform support
slightly easier for distros, since they no longer need to keep track of
a separate console prefix for these platforms.

As usual, this is where the bulk of our changes end up landing each
merge window.
The individual updates are too many to enumerate, many many platforms
have seen additions of device descriptions such that they are
functionally more complete (in fact, this is often the bulk of updates
we see).
Instead I've mostly focused on highlighting the new platforms below as
they are introduced. Sometimes the introduction is of mostly a fragment,
that later gets filled in on later releases, and in some cases it's
near-complete platform support. The latter is more common for derivative
platforms that already has similar support in-tree.
Two SoCs are slight outliers from the usual range of additions. Allwinner
support for F1C100s, a quite old SoC (ARMv5-based) shipping in the
Lychee Pi Nano platform. At the other end is NXP Layerscape LX2160A,
a 16-core 2.2GHz Cortex-A72 SoC with a large amount of I/O aimed at
infrastructure/networking.
TI updates stick out in the diff stats too, in particular because they
have moved the description of their L4 on-chip interconnect to devicetree,
which opens up for removal of even more of their platform-specific
'hwmod' description tables over the next few releases.
SoCs:
- Qualcomm QCS404 (4x Cortex-A53)
- Allwinner T3 (rebranded R40) and f1c100s (armv5)
- NXP i.MX7ULP (1x Cortex-A7 + 1x Cortex-M4)

Commit 33a48ab105 ("ibmveth: Fix DMA unmap error") fixed an issue in the
normal code path of ibmveth_xmit_start() that was originally introduced by
Commit 6e8ab30ec6 ("ibmveth: Add scatter-gather support"). This original
fix missed the error path where dma_unmap_page is wrongly called on the
header portion in descs[0] which was mapped with dma_map_single. As a
result a failure to DMA map any of the frags results in a dmesg warning
when CONFIG_DMA_API_DEBUG is enabled.

The bcm2835-thermal driver was added with commit ac178e4280
("ARM64: bcm2835: add thermal driver to default config"). Unfortunately
this was accidentally dropped by commit eb1e6716cc
("arm64: defconfig: sync with savedefconfig"). So enable the driver again.

- Rework of the kprobe/uprobe and synthetic events to consolidate all
the dynamic event code. This will make changes in the future easier.
- Partial rewrite of the function graph tracing infrastructure.
This will allow for multiple users of hooking onto functions
to get the callback (return) of the function. This is the ground
work for having kprobes and function graph tracer using one code base.
- Clean up of the histogram code that will facilitate adding more
features to the histograms in the future.
- Addition of str_has_prefix() and a few use cases. There currently
is a similar function strstart() that is used in a few places, but
only returns a bool and not a length. These instances will be
removed in the future to use str_has_prefix() instead.

In this round, we've focused on bug fixes since Pixel devices have been
shipping with f2fs. Some of them were related to hardware encryption support
which are actually not an issue in mainline, but would be better to merge
them in order to avoid potential bugs.
Enhancement:
- do GC sub-sections when the section is large
- add a flag in ioctl(SHUTDOWN) to trigger fsck for QA
- use kvmalloc() in order to give another chance to avoid ENOMEM
Bug fix:
- fix accessing memory boundaries in a malformed iamge
- GC gives stale unencrypted block
- GC counts in large sections
- detect idle time more precisely
- block allocation of DIO writes
- race conditions between write_begin and write_checkpoint
- allow GCs for node segments via ioctl()
There are various clean-ups and minor bug fixes as well.

Merge tag 'f2fs-for-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"In this round, we've focused on bug fixes since Pixel devices have
been shipping with f2fs. Some of them were related to hardware
encryption support which are actually not an issue in mainline, but
would be better to merge them in order to avoid potential bugs.
Enhancements:
- do GC sub-sections when the section is large
- add a flag in ioctl(SHUTDOWN) to trigger fsck for QA
- use kvmalloc() in order to give another chance to avoid ENOMEM
Bug fixes:
- fix accessing memory boundaries in a malformed iamge
- GC gives stale unencrypted block
- GC counts in large sections
- detect idle time more precisely
- block allocation of DIO writes
- race conditions between write_begin and write_checkpoint
- allow GCs for node segments via ioctl()
There are various clean-ups and minor bug fixes as well"

When the block device is opened with FMODE_EXCL, ref_count is set to -1.
This value doesn't get reset when the device is closed which means the
device cannot be opened again. Fix this by checking for refcount <= 0
in the release method.

forget to delete R10000_LLSC_WAR in the if-condition. So fix it.

When gcc with -pg, it'll add _mcount stub in every function. We need
implement the _mcount in kernel and ftrace depends on stackstrace.
To do: call-graph, dynamic ftrace

Trying to register the DSP platform device results in a null pointer
access:
[ 0.124184] CPU 0 Unable to handle kernel paging request at virtual address 00000000, epc == 804e305c, ra == 804e6f20
[ 0.135208] Oops[#1]:
[ 0.137514] CPU: 0 PID: 1 Comm: swapper Not tainted 4.14.87
...
[ 0.197117] epc : 804e305c bcm63xx_dsp_register+0x80/0xa4
[ 0.202838] ra : 804e6f20 board_register_devices+0x258/0x390
...
This happens because it tries to copy the passed platform data over the
platform_device's unpopulated platform_data.
Since this code has been broken since its submission, no driver was ever
submitted for it, and apparently nobody was using it, just remove it
instead of trying to fix it.
