Subject: [PATCH 1/2] linux-user: assume __NR_gettid always exists
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The gettid syscall was introduced in Linux 2.4.11. This is old enough
that we can assume it always exists and thus not bother with the
conditional backcompat logic.
