      Pull parisc updates from Helge Deller:
       "Lots of small fixes and enhancements, most noteably:
      
         - Many TLB and cache flush optimizations (Dave)
      
         - Fixed HPMC/crash handler on 64-bit kernel (Dave and myself)
      
         - Added alternative infrastructre. The kernel now live-patches itself
           for various situations, e.g. replace SMP code when running on one
           CPU only or drop cache flushes when system has no cache installed.
      
         - vmlinuz now contains a full copy of the compressed vmlinux file.
           This simplifies debugging the currently booted kernel.
      
         - Unused driver removal (Christoph)
      
         - Reduced warnings of Dino PCI bridge when running in qemu
      
         - Removed gcc version check (Masahiro)"
