Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus
* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus: (51 commits) MIPS: BCM63xx: Add integrated ethernet mac support. MIPS: BCM63xx: Add support for the Broadcom BCM63xx family of SOCs. MIPS: BCM63xx: Add Broadcom 63xx CPU definitions. MIPS: Octeon: Move some platform device registration to its own file. MIPS: Don't corrupt page tables on vmalloc fault. MIPS: Shrink the size of tlb handler MIPS: Alchemy: override loops_per_jiffy detection MIPS: hw_random: Add hardware RNG for Octeon SOCs. MIPS: Octeon: Add hardware RNG platform device. MIPS: Remove useless zero initializations. MIPS: Alchemy: get rid of allow_au1k_wait MIPS: Octeon: Set kernel_uses_llsc to false on non-SMP builds. MIPS: Allow kernel use of LL/SC to be separate from the presence of LL/SC. MIPS: Get rid of CONFIG_CPU_HAS_LLSC MIPS: Malta: Remove pointless use use of CONFIG_CPU_HAS_LLSC MIPS: Rewrite clearing of ll_bit on context switch in C MIPS: Rewrite sysmips(MIPS_ATOMIC_SET, ...) in C with inline assembler MIPS: Consolidate all CONFIG_CPU_HAS_LLSC use in a single C file. MIPS: Clean up linker script using new linker script macros. MIPS: Use PAGE_SIZE in assembly instead of _PAGE_SIZE. ...
