Subject: [PATCH 01/13] target/mips: Remove access_type argument from map_address() handler
Date: Thu, 28 Jan 2021 15:41:13 +0100 [thread overview]
Message-ID: <20210128144125.3696119-2-f4bug@amsat.org> (raw)
In-Reply-To: <20210128144125.3696119-1-f4bug@amsat.org>
TLB map_address() handlers don't use the 'access_type' argument,
remove it to simplify.
