Subject: [PATCH v24 18/18] i386: make cpu_load_efer sysemu-only
Date: Fri, 26 Feb 2021 10:49:39 +0100
Message-ID: <20210226094939.11087-19-cfontana@suse.de> (raw)
In-Reply-To: <20210226094939.11087-1-cfontana@suse.de>

cpu_load_efer is now used only for sysemu code.

Therefore, move this function implementation to
sysemu-only section of helper.c
