Commit 46571909 authored by Linus Torvalds's avatar Linus Torvalds

Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus

* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus:
  [MIPS] SB1: Check for -mno-sched-prolog if building corelis debug kernel.
  [MIPS] Sibyte: Fix race in sb1250_gettimeoffset().
  [MIPS] Sibyte: Fix interrupt timer off by one bug.
  [MIPS] Sibyte: Fix M_SCD_TIMER_INIT and M_SCD_TIMER_CNT wrong field width.
  [MIPS] Protect more of timer_interrupt() by xtime_lock.
  [MIPS] Work around bad code generation for <asm/io.h>.
  [MIPS] Simple patch to power off DBAU1200
  [MIPS] Fix DBAu1550 software power off.
  [MIPS] local_r4k_flush_cache_page fix
  [MIPS] SB1: Fix interrupt disable hazard.
  [MIPS] Get rid of the IP22-specific code in arclib.
  Update MAINTAINERS entry for MIPS.
