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()

- * Macros to force memory ordering.  In these descriptions, "previous"
- * and "subsequent" refer to program order; "visible" means that all
- * architecturally visible effects of a memory access have occurred
- * (at a minimum, this means the memory has been read or written).
- *
- *   wmb():	Guarantees that all preceding stores to memory-
- *		like regions are visible before any subsequent
- *		stores and that all following stores will be
- *		visible only after all previous stores.
- *   rmb():	Like wmb(), but for reads.
- *   mb():	wmb()/rmb() combo, i.e., all previous memory
- *		accesses are visible before all subsequent
- *		accesses and vice versa.  This is also known as
- *		a "fence."
- *
- * Note: "mb()" and its variants cannot be used as a fence to order
- * accesses to memory mapped I/O registers.  For that, mf.a needs to
- * be used.  However, we don't want to always use mf.a because (a)
- * it's (presumably) much slower than mf and (b) mf.a is supported for
- * sequential memory pages only.
