[ Upstream commit 2b16b71a05a7f056221751b906c13f8809656b1f ]

The logic there which adds a dependency note to Sphinx cache
is not taking into account that the build dir may not be
the source dir. This causes a performance regression:

$ time make O=/tmp/foo SPHINXDIRS=admin-guide htmldocs

	[OUTDATED]
	Added: set()
	Changed: {'abi-obsolete', 'abi-removed', 'abi-stable-files', 'abi-obsolete-files', 'abi-stable', 'abi', 'abi-removed-files', 'abi-testing-files', 'abi-testing', 'gpio/index', 'gpio/obsolete'}
	Removed: set()
	All docs count: 385
	Found docs count: 385

	real    0m11,324s
	user    0m15,783s
	sys     0m1,164s

To get the root cause of the problem (ABI files reported as changed),
I used this changeset:

commit e65cb011349e653ded541dddd6469c2ca813edcf upstream.

The _CRS resources in many cases want to have ResourceSource field
to be a type of ACPI String. This means that to compile properly
we need to enclosure the name path into double quotes. This will
in practice defer the interpretation to a run-time stage, However,
this may be interpreted differently on different OSes and ACPI
interpreter implementations. In particular ACPICA might not correctly
recognize the leading '^' (caret) character and will not resolve
the relative name path properly. On top of that, this piece may be
used in SSDTs which are loaded after the DSDT and on itself may also
not resolve relative name paths outside of their own scopes.
With this all said, fix documentation to use fully-qualified name
paths always to avoid any misinterpretations, which is proven to
work.

<title>fscrypt: Don't use problematic non-inline crypto engines</title>

commit b41c1d8d07906786c60893980d52688f31d114a6 upstream.

Make fscrypt no longer use Crypto API drivers for non-inline crypto
engines, even when the Crypto API prioritizes them over CPU-based code
(which unfortunately it often does).  These drivers tend to be really
problematic, especially for fscrypt's workload.  This commit has no
effect on inline crypto engines, which are different and do work well.

Specifically, exclude drivers that have CRYPTO_ALG_KERN_DRIVER_ONLY or
CRYPTO_ALG_ALLOCATES_MEMORY set.  (Later, CRYPTO_ALG_ASYNC should be
excluded too.  That's omitted for now to keep this commit backportable,
since until recently some CPU-based code had CRYPTO_ALG_ASYNC set.)

There are two major issues with these drivers: bugs and performance.

First, these drivers tend to be buggy.  They're fundamentally much more
error-prone and harder to test than the CPU-based code.  They often
don't get tested before kernel releases, and even if they do, the crypto
self-tests don't properly test these drivers.  Released drivers have
en/decrypted or hashed data incorrectly.  These bugs cause issues for
fscrypt users who often didn't even want to use these drivers, e.g.:

- https://github.com/google/fscryptctl/issues/32
- https://github.com/google/fscryptctl/issues/9
- https://lore.kernel.org/r/PH0PR02MB731916ECDB6C613665863B6CFFAA2@PH0PR02MB7319.namprd02.prod.outlook.com

These drivers have also similarly caused issues for dm-crypt users,
including data corruption and deadlocks.  Since Linux v5.10, dm-crypt
has disabled most of them by excluding CRYPTO_ALG_ALLOCATES_MEMORY.

Second, these drivers tend to be *much* slower than the CPU-based code.
This may seem counterintuitive, but benchmarks clearly show it.  There's
a *lot* of overhead associated with going to a hardware driver, off the
CPU, and back again.  To prove this, I gathered as many systems with
this type of crypto engine as I could, and I measured synchronous
encryption of 4096-byte messages (which matches fscrypt's workload):

Intel Emerald Rapids server:
   AES-256-XTS:
      xts-aes-vaes-avx512   16171 MB/s  [CPU-based, Vector AES]
      qat_aes_xts             289 MB/s  [Offload, Intel QuickAssist]

Qualcomm SM8650 HDK:
   AES-256-XTS:
      xts-aes-ce             4301 MB/s  [CPU-based, ARMv8 Crypto Extensions]
      xts-aes-qce              73 MB/s  [Offload, Qualcomm Crypto Engine]

i.MX 8M Nano LPDDR4 EVK:
   AES-256-XTS:
      xts-aes-ce              647 MB/s   [CPU-based, ARMv8 Crypto Extensions]
      xts(ecb-aes-caam)        20 MB/s   [Offload, CAAM]
   AES-128-CBC-ESSIV:
      essiv(cbc-aes-caam,sha256-lib) 23 MB/s   [Offload, CAAM]

STM32MP157F-DK2:
   AES-256-XTS:
      xts-aes-neonbs         13.2 MB/s   [CPU-based, ARM NEON]
      xts(stm32-ecb-aes)     3.1 MB/s    [Offload, STM32 crypto engine]
   AES-128-CBC-ESSIV:
      essiv(cbc-aes-neonbs,sha256-lib)
                             14.7 MB/s   [CPU-based, ARM NEON]
      essiv(stm32-cbc-aes,sha256-lib)
                             3.2 MB/s    [Offload, STM32 crypto engine]
   Adiantum:
      adiantum(xchacha12-arm,aes-arm,nhpoly1305-neon)
                             52.8 MB/s   [CPU-based, ARM scalar + NEON]

So, there was no case in which the crypto engine was even *close* to
being faster.  On the first three, which have AES instructions in the
CPU, the CPU was 30 to 55 times faster (!).  Even on STM32MP157F-DK2
which has a Cortex-A7 CPU that doesn't have AES instructions, AES was
over 4 times faster on the CPU.  And Adiantum encryption, which is what
actually should be used on CPUs like that, was over 17 times faster.

Other justifications that have been given for these non-inline crypto
engines (almost always coming from the hardware vendors, not actual
users) don't seem very plausible either:

  - The crypto engine throughput could be improved by processing
    multiple requests concurrently.  Currently irrelevant to fscrypt,
    since it doesn't do that.  This would also be complex, and unhelpful
    in many cases.  2 of the 4 engines I tested even had only one queue.

  - Some of the engines, e.g. STM32, support hardware keys.  Also
    currently irrelevant to fscrypt, since it doesn't support these.
    Interestingly, the STM32 driver itself doesn't support this either.

  - Free up CPU for other tasks and/or reduce energy usage.  Not very
    plausible considering the "short" message length, driver overhead,
    and scheduling overhead.  There's just very little time for the CPU
    to do something else like run another task or enter low-power state,
    before the message finishes and it's time to process the next one.

  - Some of these engines resist power analysis and electromagnetic
    attacks, while the CPU-based crypto generally does not.  In theory,
    this sounds great.  In practice, if this benefit requires the use of
    an off-CPU offload that massively regresses performance and has a
    low-quality, buggy driver, the price for this hardening (which is
    not relevant to most fscrypt users, and tends to be incomplete) is
    just too high.  Inline crypto engines are much more promising here,
    as are on-CPU solutions like RISC-V High Assurance Cryptography.

[ Upstream commit 01051012887329ea78eaca19b1d2eac4c9f601b5 ]

Module (SFP) eeprom GET has a lot of input params, they are all
mistakenly listed as output in the spec. Looks like kernel doesn't
output them at all. Correct what are the inputs and what the outputs.

[ Upstream commit 81b6ecca2f15922e8d653dc037df5871e754be6e ]

We should use "{usr,grp,prj}jquota=" to disable journaled quota,
rather than using off{usr,grp,prj}jquota.

<title>cgroup: Add compatibility option for content of /proc/cgroups</title>

[ Upstream commit 646faf36d7271c597497ca547a59912fcab49be9 ]

/proc/cgroups lists only v1 controllers by default, however, this is
only enforced since the commit af000ce85293b ("cgroup: Do not report
unavailable v1 controllers in /proc/cgroups") and there is software in
the wild that uses content of /proc/cgroups to decide on availability of
v2 (sic) controllers.

Add a boottime param that can bring back the previous behavior for
setups where the check in the software cannot be changed and it causes
e.g. unintended OOMs.

Also, this patch takes out cgrp_v1_visible from cgroup1_subsys_absent()
guard since it's only important to check which hierarchy (v1 vs v2) the
subsys is attached to. This has no effect on the printed message but
the code is cleaner since cgrp_v1_visible is really about mounted
hierarchies, not the content of /proc/cgroups.
