The number of interrupts lacks an upper bound, thus assuming one,
causing properly grouped "interrupts-extended" properties to be flagged
as an error by "make dtbs_check".

Fix this by adding the missing "maxItems", using the architectural
maximum of 15872 interrupts.

A recent bug report outlined that the way GICv4.1 is handled across
kexec is pretty bad. We can end-up in a situation where ITSs share
memory (this is the case when SVPET==1) and reprogram the base
registers, creating a situation where ITSs that are part of a given
affinity group see different pointers. Which is illegal. Boo.

In order to restore some sanity, reset the BASERn registers to 0
*before* probing any ITS. Although this isn't optimised at all,
this is only a once-per-boot cost, which shouldn't show up on
anyone's radar.

This is an old driver that has seen a lot of different eras of kernel
coding style. In an effort to make it easier to code for, unify the
coding style around the current norm, by accepting some of -- but
certainly not all of -- the suggestions from clang-format. This should
remove ambiguity in coding style, especially with regards to spacing,
when code is being changed or amended. Consequently it also makes code

several.

This gets rid of another abstraction we no longer need. It would be nice
if we could instead make pool an array rather than a pointer, but the
latent entropy plugin won't be able to do its magic in that case. So
instead we put all accesses to the input pool's actual data through the
input_pool_data array directly.

We no longer have an output pool. Rather, we have just a wakeup bits
threshold for /dev/random reads, presumably so that processes don't
hang. This value, random_write_wakeup_bits, is configurable anyway. So
all the no longer usefully named OUTPUT_POOL constants were doing was
setting a reasonable default for random_write_wakeup_bits. This commit
gets rid of the constants and just puts it all in the default value of
random_write_wakeup_bits.

Originally, the RNG used several pools, so having things abstracted out
over a generic entropy_store object made sense. These days, there's only
one input pool, and then an uneven mix of usage via the abstraction and
usage via &input_pool. Rather than this uneasy mixture, just get rid of
the abstraction entirely and have things always use the global. This
simplifies the code and makes reading it a bit easier.

With SHA-1 no longer being used for anything performance oriented, and
also soon to be phased out entirely, we can make up for the space added
by unrolled BLAKE2s by simply re-rolling SHA-1. Since SHA-1 is so much
more complex, re-rolling it more or less takes care of the code size
added by BLAKE2s. And eventually, hopefully we'll see SHA-1 removed

The "PAGE_SIZE - 2 - size" calculation in legacy_parse_param() is an
unsigned type so a large value of "size" results in a high positive
value instead of a negative value as expected.  Fix this by getting rid
of the subtraction.

Pull more ACPI updates from Rafael Wysocki:
 "The most significant item here is the Platform Firmware Runtime Update
  and Telemetry (PFRUT) support designed to allow certain pieces of the
  platform firmware to be updated on the fly, among other things.

  Also important is the e820 handling change on x86 that should work
  around PCI BAR allocation issues on some systems shipping since 2019.

  The rest is just a handful of assorted fixes and cleanups on top of
  the ACPI material merged previously.

  Specifics:

   - Add support for the the Platform Firmware Runtime Update and
     Telemetry (PFRUT) interface based on ACPI to allow certain pieces
     of the platform firmware to be updated without restarting the
     system and to provide a mechanism for collecting platform firmware
     telemetry data (Chen Yu, Dan Carpenter, Yang Yingliang).

   - 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).

   - Fix and clean up acpi_scan_init() (Rafael Wysocki).

   - 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)"

Pull more slab updates from Vlastimil Babka:
 "Finish the conversion to struct slab by removing slab-specific fields
  from struct page.

  The first slab update (see merge commit ca1a46d6) did most of the
  conversion, but there was also series in iommu tree removing the
  iommu's usage of struct page 'freelist' field, blocking the final
  struct page cleanup.

  Now that the iommu changes have been merged, we can finish the job"
