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 ] * git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next: (110 commits) sparc32: use flushi when run-time patching in per_cpu_patch sparc32: fix cpuid_patch run-time patching sparc32: drop unused inline functions in srmmu.c sparc32: drop unused functions in pgtsrmmu.h sparc32,leon: move leon mmu functions to leon_mm.c sparc32,leon: remove duplicate definitions in leon.h sparc32,leon: remove duplicate UART register definitions sparc32,leon: move leon ASI definitions to asi.h sparc32: move trap table to a separate file sparc64: renamed ttable.S to ttable_64.S sparc32: Remove asm/sysen.h header. sparc32: Delete asm/smpprim.h sparc32: Remove unused empty_bad_page{,_table} declarations. sparc32: Kill boot_cpu_id4 sparc32: Move GET_PROCESSOR*_ID() out of asm/asmmacro.h sparc32: Remove completely unused code from asm/cache.h sparc32: Add ucmpdi2.o to obj-y instead of lib-y. sparc32: add ucmpdi2 sparc: introduce arch/sparc/Kbuild sparc: remove obsolete documentation ...
