Pull ARM updates from Russell King:
 "First ARM push of this merge window, post me coming back from holiday.
  This is what has been in linux-next for the last few weeks.  Not much
  to say which isn't described by the commit summaries."

Perform tests of kprobes API and instruction set simulation.
config PID_IN_CONTEXTIDR
bool "Write the current PID to the CONTEXTIDR register"
depends on CPU_COPY_V6
help
Enabling this option causes the kernel to write the current PID to
the PROCID field of the CONTEXTIDR register, at the expense of some
additional instructions during context switch. Say Y here only if you
are planning to use hardware trace tools with this kernel.
