Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus
* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus: (22 commits) MIPS: Ignore vmlinux.* MIPS: Move vmlinux.ecoff to arch/mips/boot MIPS: cpumask_of_node() should handle -1 as a node MIPS: Octeon: Use non-overflowing arithmetic in sched_clock MIPS: Malta, PowerTV: Remove unnecessary "Linux started" MIPS: BCM63xx: Remove duplicate CONFIG_CMDLINE. MIPS: AR7: Remove unused prom_getchar() MIPS: PowerTV: Remove extra r4k_clockevent_init() call MIPS: Cobalt use strlcat() for the command line arguments MIPS: Octeon: Add sched_clock() to csrc-octeon.c MIPS: TXx9: Cleanup builtin-cmdline processing MIPS: PowerTV: simplify prom_init_cmdline() and merge into prom_init() MIPS: PowerTV: Remove unused platform_die() MIPS: PowerTV: Remove mips_machine_halt() MIPS: PowerTV: Remove unused ptv_memsize MIPS: PowerTV: Remove unused prom_getcmdline() MIPS: AR7: Remove kgdb_enabled MIPS: Alchemy: Correct code taking the size of a pointer MIPS: BCM63xx: Fix whitespace damaged board_bcm963xx.c MIPS: VR41xx: Use strlcat() for the command line arguments ...
