My tests are still running, but just an initial result for you,
x86_64 defconfig fails with: arch/x86/kernel/cpu/bugs.c: In function 'spectre_v2_select_mitigation': arch/x86/kernel/cpu/bugs.c:973:41: error: implicit declaration of function 'unprivileged_ebpf_enabled' [-Werror=implicit-function-declaration] 973 | if (mode == SPECTRE_V2_EIBRS && unprivileged_ebpf_enabled())
And, lots of failures in arm builds also.

All clang builds for arm are known to fail, and some arm64 clang builds will also fail. I have seen initial patches for arm64, will let the clang developers come up with the arm fix as I have no idea how to handle that. This just mirrors Linus's tree right now :)
Unless this is gcc?
thanks,
