To prevent keys from being compromised if an attacker acquires read
access to kernel memory, some inline encryption hardware can accept keys
which are wrapped by a per-boot hardware-internal key. This avoids
needing to keep the plaintext keys in kernel memory, without restricting
the number of keys that can be used. Such keys can be initially
generated either by software (in which case they must be imported to
hardware to be wrapped) or directly by the hardware. There is also a
mechanism to derive a "software secret" for cryptographic tasks that
can't be handled by inline encryption.
To support this hardware, allow struct blk_crypto_key to represent a
hardware-wrapped key as an alternative to a standard key, and make
drivers set flags in struct blk_crypto_profile to indicate which types
of keys they support. Also add the derive_sw_secret() low-level
operation, which drivers supporting wrapped keys must implement.
For more information, see the detailed documentation which this patch
adds to Documentation/block/inline-encryption.rst.
This is a reworked version of a patch which was temporily reverted by
https://android-review.googlesource.com/c/kernel/common/+/1867367, and
which originated from several ANDROID patches that were consolidated by
https://android-review.googlesource.com/c/kernel/common-patches/+/1350782.
This version of the patch matches the patch in the below "Link:" tag
that was sent upstream as an RFC. However, due to its history as
ANDROID, it remains tagged as ANDROID rather than FROMLIST.

Add UFSHCD_QUIRK_CUSTOM_CRYPTO_PROFILE which tells ufshcd-core that the
host controller supports inline encryption, but it needs to initialize
the crypto capabilities in a nonstandard way and/or it needs to override
blk_crypto_ll_ops. If enabled, the standard code won't initialize the
blk_crypto_profile; ufs_hba_variant_ops::init() must do it instead.
Note that it is permitted that the blk_crypto_profile has no keyslots.
This is needed for FMP support, as well as for wrapped key support.

TEO governor was implemented in android12-5.10, however CONFIG_CPU_IDLE_GOV_TEO
was not enabled in gki_defconfig and vendor can not select TEO governor.
This commit enable TEO and MENU governors in gki_defconfig, and vendors can
select the governor they wanted, e.g. in rc file:
write /sys/devices/system/cpu/cpuidle/current_governor "teo"
Besides, MENU governor's rating is 20, and higher than TEO governor,
so MENU governor is still the default governor if vendors not select the governor manually.

When KBUILD_MIXED_TREE points to the output folder of another kernel's
build output, Kbuild can compile a complete kernel tree's modules
against that other kernel tree's vmlinux. This is useful when two
kernel trees exist: a "Generic Kernel Image" tree and a "device kernel"
tree. Both trees are complete kernel source trees, and the "Generic
Kernel Image" should provide the kernel Image and device kernel tree
provides device driver modules.
To accomplish this, references to vmlinux in the device kernel
should point to the generic kernel's vmlinux and the device
kernel should skip compilation of built-in files.
Change ee1b16e80d
adds support for KBUILD_MIXED_TREE
in Makefile and Makefile.modpost. This change adds support for
KBUILD_MIXED_TREE in Makefile.modfinal, where vmlinux is referenced.

searches and locking
- speed up bulk insertion of items into a b-tree, which is used when

- greedy block group reclaim, pick the ones with least usable
space first
- preparatory work for send protocol updates

Commit ccaa66c8dd reinstated the kmap/kunmap that had been dropped in
commit 8c945d32e6 ("btrfs: compression: drop kmap/kunmap from lzo").
However, it seems to have done so incorrectly due to the change not
reverting cleanly, and lzo_decompress_bio() ended up not having a
matching "kunmap()" to the "kmap()" that was put back.
Also, any assert that the page pointer is not NULL should be before the
kmap() of said pointer, since otherwise you'd just oops in the kmap()
before the assert would even trigger.
I noticed this when trying to verify my btrfs merge, and things not
adding up. I'm doing this fixup before re-doing my merge, because this
commit needs to also be backported to 5.15 (after verification from the
btrfs people).

Pull erofs updates from Gao Xiang:
"There are some new features available for this cycle. Firstly, EROFS
LZMA algorithm support, specifically called MicroLZMA, is available as
an option for embedded devices, LiveCDs and/or as the secondary
auxiliary compression algorithm besides the primary algorithm in one
file.
In order to better support the LZMA fixed-sized output compression,
especially for 4KiB pcluster size (which has lowest memory pressure
thus useful for memory-sensitive scenarios), Lasse introduced a new
LZMA header/container format called MicroLZMA to minimize the original
LZMA1 header (for example, we don't need to waste 4-byte dictionary
size and another 8-byte uncompressed size, which can be calculated by
fs directly, for each pcluster) and enable EROFS fixed-sized output
compression.
Note that MicroLZMA can also be later used by other things in addition
to EROFS too where wasting minimal amount of space for headers is
important and it can be only compiled by enabling XZ_DEC_MICROLZMA.
MicroLZMA has been supported by the latest upstream XZ embedded [1] &
XZ utils [2], apply the latest related XZ embedded upstream patches by
the XZ author Lasse here.
Secondly, multiple device is also supported in this cycle, which is
designed for multi-layer container images. By working together with
inter-layer data deduplication and compression, we can achieve the
next high-performance container image solution. Our team will announce
the new Nydus container image service [3] implementation with new RAFS
v6 (EROFS-compatible) format in Open Source Summit 2021 China [4]
soon.
Besides, the secondary compression head support and readmore
decompression strategy are also included in this cycle. There are also
some minor bugfixes and cleanups, as always.

This reverts ANDROID-fscrypt-add-support-for-hardware-wrapped-keys.patch
because it is part of the hardware-wrapped keys feature, which conflicts
heavily with upstream refactoring in 5.16. I've also reworked the
hardware-wrapped key patches when proposing them upstream
(https://lore.kernel.org/linux-block/20210916174928.65529-1-ebiggers@kernel.org).
To unblock the 5.16 merge, revert the hardware-wrapped key patches for
now. I'll apply a new version of them after the 5.16 merge.

uses res as expected for the async interface"
