Sven Schnelle 6a483e56c1 parisc: entry: set W bit for !compat tasks in syscall_restore_rfi() 
commit 5fb1d3ce3e upstream.

When the kernel leaves to userspace via syscall_restore_rfi(), the
W bit is not set in the new PSW. This doesn't cause any problems
because there's no 64 bit userspace for parisc. Simple static binaries
are usually loaded at addresses way below the 32 bit limit so the W bit
doesn't matter.

Fix this by setting the W bit when TIF_32BIT is not set.
