Merge tag 'm68k-for-v6.13-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k
Pull m68k updates from Geert Uytterhoeven:
- Revive SCSI and early console support on MVME147
- Fix early kernel parameters using static keys
- Prevent and improve handling of kernel configurations that lack
specific platform, CPU, or MMU support, to avoid build failures
- Miscellaneous fixes and improvements
- Defconfig updates
* tag 'm68k-for-v6.13-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k:
m68k: defconfig: Update defconfigs for v6.12-rc1
m68k: mvme147: Reinstate early console
m68k: Make sure NR_IRQS is never zero
m68k: Select M68020 as fallback for classic
m68k: Move Sun 3 into a top-level platform option
m68k: kernel: Use str_read_write() helper function
m68k: Initialize jump labels early during setup_arch()
m68k: mvme147: Fix SCSI controller IRQ numbers
m68k: mvme147: Make mvme147_sched_init() __init
