Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc
Pull sparc fixes from David Miller:
1) Fix section mismatches in some builds, from Paul Gortmaker.
2) Need to count huge zero page mappings when doing TSB sizing, from
Mike Kravetz.
3) Fix handing of cpu_possible_mask when nr_cpus module option is
specified, from Atish Patra.
4) Don't allocate irq stacks until nr_irqs has been processed, also
from Atish Patra.
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
sparc64: Fix non-SMP build.
sparc64: Fix irq stack bootmem allocation.
sparc64: Fix cpu_possible_mask if nr_cpus is set
sparc64 mm: Fix more TSB sizing issues
sparc64: fix section mismatch in find_numa_latencies_for_group
