Hi Linus,
please pull fixes and enhancements for the parisc architecture for kernel 4.12 from:
git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-4.12-1
We added initial support for the Page Deallocation Table (PDT) which is
maintained by firmware and holds the list of memory addresses which have
physical errors. By checking that list we can instruct Linux to not include
such bad memory regions into the free memory list.
Additionally we improved the detection of CPUs where the internal cr16
cycle clocks are synchronous and as such can be used as high-resolution
clock sources.
The third enhancement is that we shut down secondary CPUs via firmware before
entering system shutdown or reboot.
The last two patches are trivial and drop unused code and simplify code.
Thanks,
Helge
