Merge tag 'asm-generic-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic

Pull ia64 removal and asm-generic updates from Arnd Bergmann:

 - The ia64 architecture gets its well-earned retirement as planned,
   now that there is one last (mostly) working release that will be
   maintained as an LTS kernel.

 - The architecture specific system call tables are updated for the
   added map_shadow_stack() syscall and to remove references to the
   long-gone sys_lookup_dcookie() syscall.

* tag 'asm-generic-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic:
  hexagon: Remove unusable symbols from the ptrace.h uapi
  asm-generic: Fix spelling of architecture
  arch: Reserve map_shadow_stack() syscall number for all architectures
  syscalls: Cleanup references to sys_lookup_dcookie()
  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

-	help
-	  If your firmware supplies the PCDP table, and you want to
-	  automatically use the primary console device it describes
-	  as the Linux console, say Y here.
-
-	  If your firmware supplies the HCDP table, and you want to
-	  use the first serial port it describes as the Linux console,
-	  say Y here.  If your EFI ConOut path contains only a UART
-	  device, it will become the console automatically.  Otherwise,
-	  you must specify the "console=hcdp" kernel boot argument.
-
-	  Neither the PCDP nor the HCDP affects naming of serial devices,
-	  so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending
-	  on how the driver discovers devices.
-
-	  You must also enable the appropriate drivers (serial, VGA, etc.)
