Subject: [PATCH v2 00/14] x86,objtool: Optimize !RETPOLINE
Date: Thu, 18 Mar 2021 18:11:03 +0100 [thread overview]
Message-ID: <20210318171103.577093939@infradead.org> (raw)
Hi,
Respin of the !RETPOLINE optimization patches.
Boris, the first 3 should probably go into tip/x86/core, it's an ungodly tangle
since it relies on the insn decoder patches in tip/x86/core, the NOP patches in
tip/x86/cpu and the alternative patches in tip/x86/alternatives.
Just to make life easy I'd suggest merging everything in x86/core and
forgetting about the other topic branches (that's what I ended up doing locally).
The remaining 11 patches depend on the first 3 as well as on the work in
tip/objtool/core, just to make life more interesting still ;-)
All except the last 4 patches should be fairly uncontroversial (I hope...)
