![]() - Shrink 'struct instruction', to improve objtool performance & memory footprint. - Other maximum memory usage reductions - this makes the build both faster, and fixes kernel build OOM failures on allyesconfig and similar configs when they try to build the final (large) vmlinux.o. - Fix ORC unwinding when a kprobe (INT3) is set on a stack-modifying single-byte instruction (PUSH/POP or LEAVE). This requires the extension of the ORC metadata structure with a 'signal' field. - Misc fixes & cleanups.
