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] N32 needs to use the compat version of sys_nfsservctl.
  [MIPS] irq_cpu: use handle_percpu_irq handler to avoid dropping interrupts.
  [MIPS] Sibyte: Fix name of clocksource.
  [MIPS] SNI: s/achknowledge/acknowledge/
  [MIPS] Makefile: Fix canonical system names
  [MIPS] vpe: handle halting TCs in an errata safe way.
  [MIPS] Sibyte: Stop timers before programming next even.
  [MIPS] Sibyte: Increase minimum oneshot timer interval to two ticks.
  [MIPS] Lasat: Fix overlap of interrupt number ranges.
  [MIPS] SNI PCIT CPLUS: workaround for b0rked irq wiring of onboard PCI bus 1
  [MIPS] Fix shadow register support.
  [MIPS] Change get_cycles to always return 0.
  [MIPS] Fix typo in R3000 TRACE_IRQFLAGS code
  [MIPS] Sibyte: Replace use of removed IO_SPACE_BASE with IOADDR.
  [MIPS] iounmap if in vr41xx_pciu_init() pci clock is over 33MHz
  [MIPS] BCM1480: Remove duplicate acknowledge of timer interrupt.
  [MIPS] Sibyte: pin timer interrupt to their cores.
  [MIPS] Qemu: Add early printk, your friend in a cold night.
  [MIPS] Convert reference to mem_map to pfn_to_page().
  [MIPS] Sibyte: resurrect old cache hack.
