f2fs: flush data when enabling checkpoint back
During checkpoint=disable period, f2fs bypasses all the synchronous IOs such as
sync and fsync. So, when enabling it back, we must flush all of them in order
to keep the data persistent. Otherwise, suddern power-cut right after enabling
checkpoint will cause data loss.

f2fs: checkpoint disabling
Note that, it requires "f2fs: return correct errno in f2fs_gc".
This adds a lightweight non-persistent snapshotting scheme to f2fs.
To use, mount with the option checkpoint=disable, and to return to
normal operation, remount with checkpoint=enable. If the filesystem
is shut down before remounting with checkpoint=enable, it will revert
back to its apparent state when it was first mounted with
checkpoint=disable. This is useful for situations where you wish to be
able to roll back the state of the disk in case of some critical
failure.

ANDROID: usb: gadget: configfs: Support multiple android instances
Some platforms may choose to create more than one gadget ConfigFS
instance, often due to the hardware having multiple USB gadget
controllers which can be used simultaneously. Currently
android_device_create() assumes only one gadget instance is ever
created and creates a single "android0" device under the "android_usb"
class, resulting in a crash if a second gadget is registered since the
global android_device pointer gets overwritten with -EEXIST.
Fix this by properly supporting multiple instances and naming the
devices "android0", "android1", etc. when each instance is created
(via mkdir). For now keep the global singleton android_device pointing
to android0 for ease of use since f_midi and f_audio_source currently
use create_function_device() without any context as to which gadget
they will be bound to.

amlogic: drm/meson: Fix plane state out-of-bounds access
For drm_plane_funcs callbacks, it was fixed to use meson specific
functions except reset callback. Not like other meson specific
callbacks, reset callback allocates drm_plane_state, so accessing
meson_plane_state from drm_plane state in other callbacks causes
out-of-bounds access. Fix plane state out-of-bounds access by using
meson specific reset callback using meson_plane_state based on
drm_atomic_helper_plane_reset().
This removes below kasan warning:

1, slab-out-of-bounds, which is caused by krealloc set shadow
memory out-of-range, since tail of page was freed.
2, use-after-free, which is caused by kasan_free_pages called
after a page freed. Because this function already called in

Solution:

2, remove call of kasan_free_pages.

arm64: alternatives: use tpidr_el2 on VHE hosts
When upstream
6d99b68933fb was back-ported to upstream v4.9.x stable as
eea59020a7f2, the edits to arch/arm64/mm/proc.S were dropped because
proc.S didn't save/restore tpidr_el1 at all. Separately, in android-4.9,
0ec37136b90e ("UPSTREAM: arm64: move sp_el0 and tpidr_el1 into
cpu_suspend_ctx") modified proc.S to save/restore tpidir_el1. These two
paths were later merged together in android-4.9. The missing edits to
proc.S should have been added in during the merge, but were not. This
change restores those edits. The original upstream change description
of
6d99b68933fb follows; this is where the missing code appeared
originally.
Commit
6d99b68933fbcf51f84fcbba49246ce1209ec193 upstream.
Now that KVM uses tpidr_el2 in the same way as Linux's cpu_offset in
tpidr_el1, merge the two. This saves KVM from save/restoring tpidr_el1
on VHE hosts, and allows future code to blindly access per-cpu variables
without triggering world-switch.
