Merge tag 'v6.1-rc6' into x86/core, to resolve conflicts

Resolve conflicts between these commits in arch/x86/kernel/asm-offsets.c:

 # upstream:
 debc5a1ec0d1 ("KVM: x86: use a separate asm-offsets.c file")

 # retbleed work in x86/core:
 5d8213864ade ("x86/retbleed: Add SKL return thunk")

... and these commits in include/linux/bpf.h:

  # upstram:
  18acb7fac22f ("bpf: Revert ("Fix dispatcher patchable function entry to 5 bytes nop")")

  # x86/core commits:
  931ab63664f0 ("x86/ibt: Implement FineIBT")
  bea75b33895f ("x86/Kconfig: Introduce function padding")

The latter two modify BPF_DISPATCHER_ATTRIBUTES(), which was removed upstream.

 Conflicts:
	arch/x86/kernel/asm-offsets.c
