Merge tag 'parisc-for-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc updates from Helge Deller: "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 which miscalculated the font start address as it gets signed vs unsigned offsets wrong - Support building an uncompressed Linux kernel - Add support for soft power-off in qemu" * tag 'parisc-for-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: fbdev: stifb: Make the STI next font pointer a 32-bit signed offset parisc: Show default CPU PSW.W setting as reported by PDC parisc/pdc: Add width field to struct pdc_model parisc: Add nop instructions after TLB inserts parisc: simplify smp_prepare_boot_cpu() parisc/agp: Use 64-bit LE values in SBA IOMMU PDIR table parisc/firmware: Use PDC constants for narrow/wide firmware parisc: Move parisc_narrow_firmware variable to header file parisc/power: Trivial whitespace cleanups and license update parisc/power: Add power soft-off when running on qemu parisc: Allow building uncompressed Linux kernel parisc: Add some missing PDC functions and constants parisc: sba-iommu: Fix comment when calculating IOC number
