Subject: [PATCH] parisc: Use _TIF_USER_WORK_MASK in entry.S
Date: Thu, 29 Oct 2020 22:01:06 +0100 [thread overview]
Message-ID: <20201029210106.GA12104@ls3530> (raw)
The constant _TIF_USER_WORK_MASK will get extended by additional flags
in the future, so check against the bits set in this mask - with the
exception of _TIF_NEED_RESCHED which was tested a few lines above.
