Subject: [Qemu-devel] [PATCH v3 02/11] linux-user: arm: pass env to get_user_code_*
Date: Sat, 21 Jun 2014 14:58:13 +0200	[thread overview]
Message-ID: <1403355502-12288-3-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1403355502-12288-1-git-send-email-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.
