One of:

  c21ac93288f0 (refs/bisect/bad) Merge tag 'v5.2-rc6' into x86/asm, to
refresh the branch
  8dbec27a242c x86/asm: Pin sensitive CR0 bits
  873d50d58f67 x86/asm: Pin sensitive CR4 bits
  7b347ad4938d (HEAD) Merge tag 'v5.2-rc5' into x86/asm, to refresh the branch
  9db9b76767f1 Documentation/x86: Fix path to entry_32.S
  7231d0165df3 x86/asm: Remove unused TASK_TI_flags from asm-offsets.c

and I suspect it's the sensitive bit pinning. But I'll delve all the way.
