Merge tag 'powerpc-4.11-6' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull more powerpc fixes from Michael Ellerman:
"These are all pretty minor. The fix for idle wakeup would be a bad bug
but has not been observed in practice.
The update to the gcc-plugins docs was Cc'ed to Kees and Jon, Kees
OK'ed it going via powerpc and I didn't hear from Jon.
- cxl: Route eeh events to all slices for pci_channel_io_perm_failure state
- powerpc/64s: Fix idle wakeup potential to clobber registers
- Revert "powerpc/64: Disable use of radix under a hypervisor"
- gcc-plugins: update architecture list in documentation
Thanks to: Andrew Donnellan, Nicholas Piggin, Paul Mackerras, Vaibhav
Jain"
