Merge additional ACPI-related updates for 5.17-rc1:

 - Ignore E820 reservations covering PCI host bridge windows on
   sufficiently recent x86 systems to avoid issues with allocating
   PCI BARs on systems where the E820 reservations cover the entire
   PCI host bridge memory window returned by the _CRS object in the
   system's ACPI tables (Hans de Goede).

 - Add more sanity checking to ACPI SPCR tables parsing (Mark
   Langsdorf).

 - Fix up ACPI APD (AMD Soc) driver initialization (Jiasheng Jiang).

 - Drop unnecessary "static" from the ACPI PCC address space handling
   driver added recently (kernel test robot).

* acpi-x86:
  x86/PCI: Ignore E820 reservations for bridge windows on newer systems

* acpi-tables:

Rename the "out" label in acpi_scan_init() to "unlock", which is
a better match for its purpose, and fix up its alignment.

No functional impact.

It should be perfectly fine to use ACPI if the "fixed" power or sleep
buttons cannot be initialized.  Moreover, running acpi_bus_scan()
successfully on ACPI_ROOT_OBJECT generally causes many devices to
be enumerated and probed, possibly including the entire PCI bus, so
unregistering acpi_root if the registration of the "fixed" buttons
fails is rather unhelpful.

For this reason, do not fail acpi_scan_init() when
acpi_bus_scan_fixed() fails and turn the latter into a void function.

While at it, drop the outdated and misleading comment from
acpi_bus_scan_fixed().

The only caller of acpi_scan_init(), acpi_init(), doesn't check its
return value, so turn it into a void function.

This avoids complaints from the Smatch static checker that the
function should return a negative error code when it fails, which
is not really a problem in this particular case.

No intentional functional impact.

Because devres_alloc() may fail, devm_ioremap() may return NULL.

Then, 'clk_data->base' will be assigned to clkdev->data->base in
platform_device_register_data().

The PTR_ERR_OR_ZERO() check on clk_data does not cover 'base', so
it is better to add an explicit check against NULL after updating
it.

Some BIOS-es contain a bug where they add addresses which map to system
RAM in the PCI host bridge window returned by the ACPI _CRS method, see
commit 4dc2287c ("x86: avoid E820 regions when allocating address
space").

To work around this bug Linux excludes E820 reserved addresses when
allocating addresses from the PCI host bridge window since 2010.

Recently (2019) some systems have shown-up with E820 reservations which
cover the entire _CRS returned PCI bridge memory window, causing all
attempts to assign memory to PCI BARs which have not been setup by the
BIOS to fail. For example here are the relevant dmesg bits from a
Lenovo IdeaPad 3 15IIL 81WE:

 [mem 0x000000004bc50000-0x00000000cfffffff] reserved
 pci_bus 0000:00: root bus resource [mem 0x65400000-0xbfffffff window]

The ACPI specifications appear to allow this new behavior:

The relationship between E820 and ACPI _CRS is not really very clear.
ACPI v6.3, sec 15, table 15-374, says AddressRangeReserved means:

  This range of addresses is in use or reserved by the system and is
  not to be included in the allocatable memory pool of the operating
  system's memory manager.

and it may be used when:

  The address range is in use by a memory-mapped system device.

Furthermore, sec 15.2 says:

  Address ranges defined for baseboard memory-mapped I/O devices, such
  as APICs, are returned as reserved.

A PCI host bridge qualifies as a baseboard memory-mapped I/O device,
and its apertures are in use and certainly should not be included in
the general allocatable pool, so the fact that some BIOS-es reports
the PCI aperture as "reserved" in E820 doesn't seem like a BIOS bug.

So it seems that the excluding of E820 reserved addresses is a mistake.

Ideally Linux would fully stop excluding E820 reserved addresses,
but then the old systems this was added for will regress.
Instead keep the old behavior for old systems, while ignoring
the E820 reservations for any systems from now on.

Old systems are defined here as BIOS year < 2018, this was chosen to make
sure that E820 reservations will not be used on the currently affected
systems, while at the same time also taking into account that the systems
for which the E820 checking was originally added may have received BIOS
updates for quite a while (esp. CVE related ones), giving them a more
recent BIOS year then 2010.

Commit 2c865a8a ("netfilter: nf_tables: add rule blob layout") never
initialized the new 'data_size' variable.

I'm not sure how it ever worked, but it might have worked almost by
accident - gcc seems to occasionally miss these kinds of 'variable used
uninitialized' situations, but I've seen it do so because it ended up
zero-initializing them due to some other simplification.

But clang is very unhappy about it all, and correctly reports

    net/netfilter/nf_tables_api.c:8278:4: error: variable 'data_size' is uninitialized when used here [-Werror,-Wuninitialized]
                            data_size += sizeof(*prule) + rule->dlen;
                            ^~~~~~~~~
    net/netfilter/nf_tables_api.c:8263:30: note: initialize the variable 'data_size' to silence this warning
            unsigned int size, data_size;
                                        ^
                                         = 0
    1 error generated.

and this fix just initializes 'data_size' to zero before the loop.

This reverts commit a896f870.

It causes odd flickering on my Radeon RX580 (PCI ID 1002:67df rev e7,
subsystem ID 1da2:e353).

Bisected right to this commit, and reverting it fixes things.

Pull slab updates from Vlastimil Babka:

 - Separate struct slab from struct page - an offshot of the page folio
   work.

   Struct page fields used by slab allocators are moved from struct page
   to a new struct slab, that uses the same physical storage. Similar to
   struct folio, it always is a head page. This brings better type
   safety, separation of large kmalloc allocations from true slabs, and
   cleanup of related objcg code.

 - A SLAB_MERGE_DEFAULT config optimization.

Pull random number generator updates from Jason Donenfeld:
 "These a bit more numerous than usual for the RNG, due to folks
  resubmitting patches that had been pending prior and generally renewed
  interest.

  There are a few categories of patches in here:

   1) Dominik Brodowski and I traded a series back and forth for a some
      weeks that fixed numerous issues related to seeds being provided
      at extremely early boot by the firmware, before other parts of the
      kernel or of the RNG have been initialized, both fixing some
      crashes and addressing correctness around early boot randomness.
      One of these is marked for stable.

   2) I replaced the RNG's usage of SHA-1 with BLAKE2s in the entropy
      extractor, and made the construction a bit safer and more
      standard. This was sort of a long overdue low hanging fruit, as we
      were supposed to have phased out SHA-1 usage quite some time ago
      (even if all we needed here was non-invertibility). Along the way
      it also made extraction 131% faster. This required a bit of
      Kconfig and symbol plumbing to make things work well with the
      crypto libraries, which is one of the reasons why I'm sending you
      this pull early in the cycle.

   3) I got rid of a truly superfluous call to RDRAND in the hot path,
      which resulted in a whopping 370% increase in performance.

   4) Sebastian Andrzej Siewior sent some patches regarding PREEMPT_RT,
      the full series of which wasn't ready yet, but the first two
      preparatory cleanups were good on their own. One of them touches
      files in kernel/irq/, which is the other reason why I'm sending
      you this pull early in the cycle.

   5) Other assorted correctness fixes from Eric Biggers, Jann Horn,
      Mark Brown, Dominik Brodowski, and myself"

Pull s390 updates from Heiko Carstens:
 "Besides all the small improvements and cleanups the most notable part
  is the fast vector/SIMD implementation of the ChaCha20 stream cipher,
  which is an adaptation of Andy Polyakov's code for the kernel.

  Summary:

   - add fast vector/SIMD implementation of the ChaCha20 stream cipher,
     which mainly adapts Andy Polyakov's code for the kernel

   - add status attribute to AP queue device so users can easily figure
     out its status

   - fix race in page table release code, and and lots of documentation

   - remove uevent suppress from cio device driver, since it turned out
     that it generated more problems than it solved problems

   - quite a lot of virtual vs physical address confusion fixes

   - various other small improvements and cleanups all over the place"

Pull arm64 updates from Catalin Marinas:

 - KCSAN enabled for arm64.

 - Additional kselftests to exercise the syscall ABI w.r.t. SVE/FPSIMD.

 - Some more SVE clean-ups and refactoring in preparation for SME
   support (scalable matrix extensions).

 - BTI clean-ups (SYM_FUNC macros etc.)

 - arm64 atomics clean-up and codegen improvements.

 - HWCAPs for FEAT_AFP (alternate floating point behaviour) and
   FEAT_RPRESS (increased precision of reciprocal estimate and
   reciprocal square root estimate).

 - Use SHA3 instructions to speed-up XOR.

 - arm64 unwind code refactoring/unification.

 - Avoid DC (data cache maintenance) instructions when DCZID_EL0.DZP ==
   1 (potentially set by a hypervisor; user-space already does this).

 - Perf updates for arm64: support for CI-700, HiSilicon PCIe PMU,
   Marvell CN10K LLC-TAD PMU, miscellaneous clean-ups.

 - Other fixes and clean-ups; highlights: fix the handling of erratum
   1418040, correct the calculation of the nomap region boundaries,
   introduce io_stop_wc() mapped to the new DGH instruction (data
   gathering hint).
