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

Pull MIPS update from Ralf Baechle:
 "To avoid unnecessary risk and work the preemption fixes are combined
  with some preparatory work that isn't strictly required.  So it's
  really just 3 fixes:

   - Get is_compat_task() to do the right thing while simplifying it.
     The unnecessary complexity hid a rarely striking bug which could be
     triggered by ext3/ext4 under certain circumstances.
   - Resolve a preemption issue in the irqflags.h functions for kernels
     built to support pre-MIPS32 / pre-MIPS64 Release 2 processors.
   - Fix the interrupt number of the MIPS Malta's CBUS UART."

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
  MIPS: Malta: Fix interupt number of CBUS UART.
  MIPS: Make irqflags.h functions preempt-safe for non-mipsr2 cpus
  MIPS: Remove irqflags.h dependency from bitops.h
  MIPS: bitops.h: Change use of 'unsigned short' to 'int'
  MIPS: compat: Delete now unused TIF_32BIT.
  MIPS: compat: Implement is_compat_task() by testing for 32-bit address space.
  MIPS: compat: Fix use of TIF_32BIT_ADDR vs _TIF_32BIT_ADDR
