* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus:
  [MIPS] vpe: Add missing "space"
  [MIPS] Compliment va_start() with va_end().
  [MIPS] IP22: Fix broken eeprom access by using __raw_readl/__raw_writel
  [MIPS] IP22: Fix broken EISA interrupt setup by switching to generic i8259
  [MIPS] 64-bit Sibyte kernels need DMA32.
  [MIPS] Only build r4k clocksource for systems that work ok with it.
  [MIPS] Handle R4000/R4400 mfc0 from count register.
  [MIPS] Fix possible hang in LL/SC futex loops.
  [MIPS] Fix context DSP context / TLS pointer switching bug for new threads.
  [MIPS] IP32: More interrupt renumbering fixes.
  [MIPS] time: MIPSsim's plat_time_init doesn't need to be irq safe.
  [MIPS] time: Fix negated condition in cevt-r4k driver.
  [MIPS] Fix pcspeaker build.
