Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc
Pull sparc fixes from David Miller:
1) With modern networking cards we can run out of 32-bit DMA space, so
support 64-bit DMA addressing when possible on sparc64. From Dave
Tushar.
2) Some signal frame validation checks are inverted on sparc32, fix
from Andreas Larsson.
3) Lockdep tables can get too large in some circumstances on sparc64,
add a way to adjust the size a bit. From Babu Moger.
4) Fix NUMA node probing on some sun4v systems, from Thomas Tai.
