Subject: [PATCH 0/3] objtool: Constify most of the instruction decoding loop
Date: Wed, 22 Apr 2020 12:32:02 +0200	[thread overview]
Message-ID: <20200422103205.61900-1-mingo@kernel.org> (raw)

Constify some of the decoding primitives, to ascertain and enforce that
arch_decode_instructions() is a read-only consumer of the various ELF data
structures. (Which it is.)

This is in preparation to parallelize the most expensive parts of objtool,
but makes sense independently as well.

These bits can also be found at:

  git git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git WIP.core/objtool

(Subject to rebasing.)

Thanks,

     Ingo
