pKVM modules may need to be notified in case of unexpected same-level
EL2 exceptions, which result in a hyp panic. To do so, introduce a new
notifier on the hyp_panic path.

pKVM modules may need to temporarily map large-ish physically contiguous
regions of memory when bootstrapping themselves. In order to support
this use-case, introduce two new APIs in the module_ops struct allowing
to map and unmap pages in pKVM's linear map range. Since pKVM's page
ownership infrastructure relies on linear map PTEs, this needs to be
done with special care. To avoid any problem, let's count the number of
pages mapped by modules and unsure they have been unmapped before
reaching the point of deprivilege.

It comes with the commit efbb82d3b0db ("ANDROID: Add a vendor hook
that allow a module to modify the wake flag"). A vendor who want to
hook sock_def_readable can set this vendor-specific wake flag.
sock_def_readable ->
(vendor hook will call __wake_up_sync_key with a custom mode) ->
__wake_up_sync_key ->
(vendor hook changes wake_flags per the custom mode) ->
__wake_up_common -> default_wake_function
It is an Android-specific since it works with a vendor hook.

The new sysctl sched_pelt_multiplier allows a user to set a clock
multiplier to x2 or x4 (x1 being the default). This clock multiplier
artificially speeds up PELT ramp up/down similarly to use a faster
half-life than the default 32ms.
- x1: 32ms half-life
- x2: 16ms half-life
- x4: 8ms half-life
Internally, a new clock is created: rq->clock_task_mult. It sits in the
clock hierarchy between rq->clock_task and rq->clock_pelt.

(https://lore.kernel.org/r/20211021181608.54127-4-ebiggers@kernel.org)
I've since made several updates to that patch and it is now at v7.
This commit brings in the updates from v3 to v7, to the extent possible
while retaining compatibility with the UAPI and on-disk format used for
this feature in Android. This mainly includes some improved log
messages, and compatibility with the blk-crypto updates.

I've since made several updates to that patch and it is now at v7.
This commit brings in the updates from v3 to v7. The main change is
making blk_crypto_derive_sw_secret() operate on a struct block_device,
and adding blk_crypto_hw_wrapped_keys_compatible(). This aligns with
changes upstream in v6.1 and v6.2 that removed block-layer internal
structures from the API that blk-crypto exposes to upper layers.
There's also a slight change in prototype for ->derive_sw_secret, so a
couple out-of-tree drivers will need to be updated, but people
maintaining out-of-tree drivers know what they are dealing with anyway.

a) If kthread_run() fails in f2fs_create_flush_cmd_control(), it will
release SM_I(sbi)->fcc_info,
- mount -o noflush_merge /dev/vda /mnt/f2fs
- mount -o remount,flush_merge /dev/vda /mnt/f2fs -- kthread_run() fails
- dd if=/dev/zero of=/mnt/f2fs/file bs=4k count=1 conv=fsync
b) we will never allocate memory for SM_I(sbi)->fcc_info w/ below

- mount -o ro /dev/vda /mnt/f2fs
- mount -o rw,remount /dev/vda /mnt/f2fs
- dd if=/dev/zero of=/mnt/f2fs/file bs=4k count=1 conv=fsync

- allocate SM_I(sbi)->fcc_info even if readonly is on.

Reverse migration is used to do the balancing the occupancy of memory
zones in a node in the system whose imabalance may be caused by
migration of pages to other zones by an operation, eg: hotremove and
then hotadding the same memory. In this case there is a lot of free
memory in newly hotadd memory which can be filled up by the previous
migrated pages(as part of offline/hotremove) thus may free up some
pressure in other zones of the node.

These old unused definitions were originally left around to prevent the
same mode numbers from being reused. However, we've now decided to
reuse the mode numbers anyway. So let's completely remove these old
unused definitions to avoid confusion. There is no reason for any code
to be using these constants in any way; and indeed, Debian Code Search
shows no uses of them (other than in copies or translations of the
header). So this should be perfectly safe.
