Message-Id: <3de0ca692fa8bf414c5e3d7afe3e6195d1a10e1f.1454261517.git.luto@kernel.org> Date: Sun, 31 Jan 2016 09:33:28 -0800 From: Andy Lutomirski <luto@...nel.org> To: x86@...nel.org Cc: linux-kernel@...r.kernel.org, Brian Gerst <brgerst@...il.com>, Borislav Petkov <bp@...en8.de>, Andy Lutomirski <luto@...nel.org> Subject: [PATCH 3/3] x86/syscalls/64: Mark sys_iopl as using ptregs sys_iopl both reads and writes pt_regs->flags. Mark it as using ptregs. This isn't strictly necessary, as pt_regs->flags is available even in the fast path, but this is very lightweight now that we have syscall qualifiers and it could avoid some pain down the road.
