Subject: [GIT PULL] parisc architecture fixes for v6.7-rc1

Hi Linus,

please pull the fixes and updates for the parisc architecture for 6.7-rc1:

Usual fixes and updates:
* Add up to 12 nops after TLB inserts for PA8x00 CPUs as the specification
  requires (Dave Anglin)
* Simplify the parisc smp_prepare_boot_cpu() code (Russell King)
* Use 64-bit little-endian values in SBA IOMMU PDIR table for AGP

Since there is upcoming support for booting a 64-bit kernel on QEMU,
some corner cases were fixed and improvements added:
* Fix 64-bit kernel crash in STI (graphics console) font setup code
* Support building an uncompressed Linux kernel
* Add support for soft power-off in qemu

Thanks,
Helge

  fbdev: stifb: Make the STI next font pointer a 32-bit signed offset (2023-10-30 14:54:41 +0100)

----------------------------------------------------------------
parisc architecture fixes and updates for kernel v6.7-rc1:

- Add nop instructions after TLB inserts for PA8x00 CPUs
- Fix a 64-bit kernel crash in STI font routines which miscalculates
  the font start address as it gets signed vs unsigned offsets wrong
- Support building an uncompressed Linux kernel
- Simplify smp_prepare_boot_cpu() function
- Support for soft power-off in qemu
- Use 64-bit little-endian values in SBA IOMMU PDIR table for AGP

----------------------------------------------------------------

      parisc: sba-iommu: Fix comment when calculating IOC number
      parisc: Add some missing PDC functions and constants
      parisc: Allow building uncompressed Linux kernel
      parisc/power: Add power soft-off when running on qemu
      parisc/power: Trivial whitespace cleanups and license update
      parisc: Move parisc_narrow_firmware variable to header file
      parisc/firmware: Use PDC constants for narrow/wide firmware
      parisc/agp: Use 64-bit LE values in SBA IOMMU PDIR table
