Merge tag 'powerpc-4.10-3' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fixes from Michael Ellerman:
"The main change is we're reverting the initial stack protector support
we merged this cycle. It turns out to not work on toolchains built
with libc support, and fixing it will be need to wait for another
release.
And the rest are all fairly minor:
- Some pasemi machines were not booting due to a missing error check
in prom_find_boot_cpu()
- In EEH we were checking a pointer rather than the bool it pointed
to
- The clang build was broken by a BUILD_BUG_ON() we added.
- The radix (Power9 only) version of map_kernel_page() was broken if
our memory size was a multiple of 2MB, which it generally isn't
Thanks to: Darren Stevens, Gavin Shan, Reza Arbab"
