Hi Linus,

Please pull three important fixes for the parisc architecture for v4.9 from
git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-4.9-5

Dave provided two patches: One which purges the TLB before setting a PTE entry
and a second one which drops unnecessary TLB flushes. Both patches have been
tested for one week on the debian buildd servers and prevent random
segmentation faults.

The patch from me fixes a crash at boot inside the TLB measuring code on SMP
machines with PA8000-PA8700 CPUs (specifically A500-44 and J5000 servers).


Helge Deller (1):
parisc: Fix TLB related boot crash on SMP machines

John David Anglin (2):
parisc: Purge TLB before setting PTE
parisc: Remove unnecessary TLB purges from flush_dcache_page_asm and flush_icache_page_asm
