Subject: [GIT PULL] parisc architecture fixes for 4.9
Date: Thu, 8 Dec 2016 22:58:36 +0100 [thread overview]
Message-ID: <20161208215836.GA23993@ls3530> (raw)
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
