Subject: [Qemu-devel] [PATCH 4/5] ppc: Improve a few more helper flags
Date: Sun, 31 Jul 2016 15:13:12 +1000	[thread overview]
Message-ID: <1469941993-27576-4-git-send-email-benh@kernel.crashing.org> (raw)
In-Reply-To: <1469941993-27576-1-git-send-email-benh@kernel.crashing.org>

Mostly turn "store" type of helpers into TCG_CALL_NO_WG because
they can take exceptions. Also fixup_thrm doesn't read nor write
the tracked environment.
