Merge branch 'nmi' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull NMI backtrace update from Russell King:
"These changes convert the x86 NMI handling to be a library
implementation which other architectures can make use of. Thomas
Gleixner has reviewed and tested these changes, and wishes me to send
these rather than taking them through the tip tree.
The final patch in the set adds an initial implementation using this
infrastructure to ARM, even though it doesn't send the IPI at "NMI"
level. Patches are in progress to add the ARM equivalent of NMI, but
we still need the IRQ-level fallback for systems where the "NMI" isn't
available due to secure firmware denying access to it"
* 'nmi' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
ARM: add basic support for on-demand backtrace of other CPUs
nmi: x86: convert to generic nmi handler
nmi: create generic NMI backtrace implementation
