Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next

Pull sparc updates from David Miller:

1) Kill off support for sun4c and Cypress sun4m chips.

   And as a result we were able to also kill off that ugly btfixup thing
   that required multi-stage links of the final vmlinux image in the
   Kbuild system.  This should make the kbuild maintainers really happy.

   Thanks a lot to Sam Ravnborg for his tireless efforts to get this
   going.

2) Convert sparc64 to nobootmem.  I suspect now with sparc32 being a lot
   cleaner, it should be able to fall in line and modernize in this area
   too.

3) Make sparc32 use generic clockevents, from Tkhai Kirill.

[ I fixed up the BPF rules, and tried to clean up the build rules too.
  But I don't have - or want - a sparc cross-build environment, so the
  BPF rule bug and the related build cleanup was all done with just a
  bare "make -n" pseudo-test.      - Linus ]
