[PATCH v3 49/64] objtool: Unify STACK_FRAME_NON_STANDARD entry sizes
From: Josh Poimboeuf
Date: Thu Jun 26 2025 - 20:05:25 EST
The C implementation of STACK_FRAME_NON_STANDARD emits 8-byte entries,
whereas the asm version's entries are only 4 bytes.
Make them consistent by converting the asm version to 8-byte entries.
This is much easier than converting the C version to 4-bytes, which
would require awkwardly putting inline asm in a dummy function in order
to pass the 'func' pointer to the asm.
