Subject: [Qemu-devel] [PATCH 01/15] softmmu: provide tlb_vaddr_to_host function for user mode
Date: Sat, 13 Jun 2015 00:45:49 +0200 [thread overview]
Message-ID: <1434149163-16639-2-git-send-email-aurelien@aurel32.net> (raw)
In-Reply-To: <1434149163-16639-1-git-send-email-aurelien@aurel32.net>
To avoid to many #ifdef in target code, provide a tlb_vaddr_to_host for
both user and softmmu modes. In the first case the function always
succeed and just call the g2h function.
