Pull parisc updates from Helge Deller:
 "Lots of small enhancements and fixes in this patchset:

   - improved the x86-64 compatibility for PCI cards by returning -1UL
     for timed out MMIO transactions (instead of crashing)

   - fixed HPMC handler for PAT machines: size needs to be multiple of 16

   - prepare machine_power_off() to be able to turn rp3410 and c8000
     machines off via IMPI

   - added code to extract machine info for usage with qemu

   - some init sections fixes

   - lots of fixes for sparse-, ubsan- and uninitalized variables
     warnings"
