So I think this is a new build warning/failure (config attached),
from objtool:

  arch/x86/boot/startup/sev-startup.o: warning: objtool: vc_check_opcode_bytes+0x53: can't find switch jump table

Note that it's a randconfig.

No such warning triggers on:

  a1b582a3ff61 Merge branch 'x86/urgent' into x86/boot, to merge dependent commit and upstream fixes

which is the base of the commits:

  ff4c0560ab02 x86/asm: Retire RIP_REL_REF()
  681e2901330c x86/boot: Drop RIP_REL_REF() uses from early SEV code
  a3cbbb4717e1 x86/boot: Move SEV startup code into startup/
  234cf67fc3bd x86/sev: Split off startup code from core code
  b66fcee1574e x86/sev: Move noinstr NMI handling code into separate source file
  092071e0f63c vmlinux.lds: Include .data.rel[.local] into .data section
  a1b582a3ff61 Merge branch 'x86/urgent' into x86/boot, to merge dependent commit and upstream fixes

Unsurprisingly:

  starship:~/tip> git bisect bad

  a3cbbb4717e120f9e53fa7685909b310f7e99bf5 is the first bad commit
