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.
