FYI, we noticed a +1483 bytes kernel size regression due to commit:

commit: db90b3e81ffb6af5d4ae0073f707dc4053d258bb (perf/x86/intel/lbr: Support Architectural LBR)
https://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git perf/core

Details as below (size data is obtained by `nm --size-sort vmlinux`):
