Subject: [Qemu-devel] [PATCH v2 02/18] linux-user: arm: pass env to get_user_code_*
Date: Tue,  1 Mar 2016 22:56:06 -0800	[thread overview]
Message-ID: <d8be93661b4d95074485e362b50358362f8ca28d.1456901522.git.crosthwaite.peter@gmail.com> (raw)
In-Reply-To: <cover.1456901522.git.crosthwaite.peter@gmail.com>
In-Reply-To: <cover.1456901522.git.crosthwaite.peter@gmail.com>

From: Paolo Bonzini <pbonzini@redhat.com>

This matches the idiom used by get_user_data_* later in the series,
and will help when bswap_code will be replaced by SCTLR.B.
