Pull m68k updates from Geert Uytterhoeven:

 - Fix forward secrecy of RNG seed boot record handling

 - Make RNG seed boot record handling generic for all m68k platforms
   using bootinfo

 - defconfig updates

 - Minor fixes and improvements

* tag 'm68k-for-v6.1-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k:
  m68k: Rework BI_VIRT_RNG_SEED as BI_RNG_SEED
  m68k: Process bootinfo records before saving them
  m68k: defconfig: Update defconfigs for v6.0-rc2
  m68k: Allow kexec on M68KCLASSIC with MMU enabled only
  m68k: Move from strlcpy with unused retval to strscpy
