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] Count timer interrupts correctly.
  [MIPS] SMTC and non-SMTC kernel and modules are incompatible
  [MIPS] EMMA2RH: Disable GEN_RTC, it can't possibly work.
  [MIPS] Remove a duplicated local variable in test_and_clear_bit()
  [MIPS] use compat_siginfo in rt_sigframe_n32
  [MIPS] 20K: Handle WAIT related bugs according to errata information
  [MIPS] AP/SP requires shadow registers, auto enable support.
  [MIPS] Fix pb1500 reg B access
  [MIPS] Alchemy: Fix wrong cast
  [MIPS] remove "support for" from system type entry
  [MIPS] add io_map_base to pci_controller on Cobalt
  [MIPS] __ucmpdi2 arguments are unsigned long long.
