Merge tag 'tag-remove-ia64' of git://git.kernel.org/pub/scm/linux/kernel/git/ardb/linux into asm-generic

Remove IA-64 architecture support

Fix the IA-64 build before removing the architecture support completely.
This makes v6.6 LTS the final Linux release with IA-64/Itanium support.

* tag 'tag-remove-ia64' of git://git.kernel.org/pub/scm/linux/kernel/git/ardb/linux:
  Documentation: Drop or replace remaining mentions of IA64
  lib/raid6: Drop IA64 support
  Documentation: Drop IA64 from feature descriptions
  kernel: Drop IA64 support from sig_fault handlers
  arch: Remove Itanium (IA-64) architecture
  acpi: Provide ia64 dummy implementation of acpi_proc_quirk_mwait_check()
