Message-Id: <1453401286-26966-1-git-send-email-bp@alien8.de> Date: Thu, 21 Jan 2016 19:34:41 +0100 From: Borislav Petkov <bp@...en8.de> To: "H. Peter Anvin" <hpa@...or.com> Cc: Andy Lutomirski <luto@...capital.net>, Brian Gerst <brgerst@...il.com>, X86 ML <x86@...nel.org>, LKML <linux-kernel@...r.kernel.org> Subject: [RFC PATCH 0/5] x86/cpufeature: Cleanups and improvements From: Borislav Petkov <bp@...e.de> So here's the first version of what we talked about. I've ran randbuilds on it for a night because of patch 1 with all the header reorg and we all know how that can be painful. So this version passes all randbuild configs I had generated. In talking about patch 1, it is a bit big but if you look at the diffstat, it basically is fixing a bunch of includes and the meat of it being the carving out of the X86_FEATURE_* things to a separate file. Rest of the patches should be pretty self-explanatory, check the respective commit messages. I haven't tested it functionally yet (booting in kvm doesn't really count) - thus the RFC tag. I thought I should send it out first so that people can doublecheck me on the direction this is going. Thanks!
