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).
Thanks,
Helge
