Merge tag 'metag-for-v3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/metag
Pull metag architecture changes from James Hogan:
- A change to remove the last dependence on bootloader exception
handlers so that QEMU can more easily boot an SMP Linux/Meta kernel
image directly.
- A fix for a minor off by one error in a BUG_ON condition found by Dan
Carpenter.
* tag 'metag-for-v3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/metag:
metag: off by one in setup_bootmem_node()
metag: handle low level kicks directly
