Subject: [PATCH 0/3] x86, mpx: Fixes for 3.19
Date: Thu, 08 Jan 2015 14:30:18 -0800	[thread overview]
Message-ID: <20150108223018.A57DEE63@viggo.jf.intel.com> (raw)

This is a resend of stuff sent shortly before the holidays,
plus an addition to the prctl() code to make it more strict
about empty arguments.

Thanks for Andi Lutomirski and Michael Kerrisk for noticing
some of this stuff.

 * Explictly disable 32-bit binaries on 64-bit kernels
 * Fix possible performance regression at unmap time
 * Be strict about enforcing empty prctl() arguments
