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
include/linux/bpf.h
