Pull libata fixlets from Jens Axboe:

 - A fix for PIO highmem (Christoph)

 - Kill HAVE_IDE as it's now unused (Lukas)

* tag 'libata-5.14-2021-07-30' of git://git.kernel.dk/linux-block:
  arch: Kconfig: clean up obsolete use of HAVE_IDE
  libata: fix ata_pio_sector for CONFIG_HIGHMEM

The arch-specific Kconfig files use HAVE_IDE to indicate if IDE is
supported.

As IDE support and the HAVE_IDE config vanishes with commit b7fb14d3ac63
("ide: remove the legacy ide driver"), there is no need to mention
HAVE_IDE in all those arch-specific Kconfig files.

The issue was identified with ./scripts/checkkconfigsymbols.py.

The defconfigs switched Mac from the deprecated CONFIG_BLK_DEV_PLATFORM
to CONFIG_PATA_PLATFORM.  However, the latter depends on
CONFIG_HAVE_PATA_PLATFORM, which thus must be selected first.

Pull asm/unaligned.h unification from Arnd Bergmann:
 "Unify asm/unaligned.h around struct helper

  The get_unaligned()/put_unaligned() helpers are traditionally
  architecture specific, with the two main variants being the
  "access-ok.h" version that assumes unaligned pointer accesses always
  work on a particular architecture, and the "le-struct.h" version that
  casts the data to a byte aligned type before dereferencing, for
  architectures that cannot always do unaligned accesses in hardware.

  Based on the discussion linked below, it appears that the access-ok
  version is not realiable on any architecture, but the struct version
  probably has no downsides. This series changes the code to use the
  same implementation on all architectures, addressing the few
  exceptions separately"
