Subject: [PATCH 0/4] objtool validation of static branches
Date: Mon, 15 Jan 2018 17:44:28 +0100 [thread overview]
Message-ID: <20180115164428.498966552@infradead.org> (raw)
Because dwmw2 is a wee bit paranoid and GCC has a history of being slightly
retarded at times; here are a few patches that validate it will in fact
generate sensible code for static branches.
With this I hope to take away dwmw2's concerns for hard relying on asm-goto.
With that, we can stop sprinkling LFENCE all over the place with the IBRS/IBPB
patches.
