Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus
* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus: (80 commits) [MIPS] tlbex.c: Cleanup __init usage. [MIPS] WRPPMC serial support move to platform device [MIPS] R1: Fix hazard barriers to make kernels work on R2 also. [MIPS] VPE: reimplement ELF loader. [MIPS] cleanup WRPPMC include files [MIPS] Add BUG_ON assertion for attempt to run kernel on the wrong CPU type. [MIPS] SMP: Use ISO C struct initializer for local structs. [MIPS] SMP: Kill useless casts. [MIPS] Kill num_online_cpus() loops. [MIPS] SMP: Implement smp_call_function_mask(). [MIPS] Make facility to convert CPU types to strings generally available. [MIPS] Convert list of CPU types from #define to enum. [MIPS] Optimize get_unaligned / put_unaligned implementations. [MIPS] checkfiles: Fix "need space after that ','" errors. [MIPS] Fix "no space between function name and open parenthesis" warnings. [MIPS] Allow hardwiring of the CPU type to a single type for optimization. [MIPS] tlbex: Size optimize code by declaring a few functions inline. [MIPS] pg-r4k.c: Dump the generated code [MIPS] Cobalt: Remove cobalt_machine_power_off() [MIPS] Cobalt: Move reset port definition to arch/mips/cobalt/reset.c ...
