Merge branch 'parisc-4.4-4' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc system call restart fix from Helge Deller:
"The architectural design of parisc always uses two instructions to
call kernel syscalls (delayed branch feature). This means that the
instruction following the branch (located in the delay slot of the
branch instruction) is executed before control passes to the branch
destination.
Depending on which assembler instruction and how it is used in
usersapce in the delay slot, this sometimes made restarted syscalls
like futex() and poll() failing with -ENOSYS"
