As I mentioned to a few ppc folks at LCA08 I plan to use
the LMB code from powerpc as a basis for NUMA support on
sparc64.
There are two changes.
1) Move arch/powerpc/mm/lmb.c to lib/lmb.c, put the main
interface bits in include/linux/lmb.h, put arch-specific
bits in asm/lmb.h and add Kconfig machinery to build this
stuff on sparc64.
2) Fix a bug in lmb_alloc() wherein the size was not aligned
so we could easily run out of reserve blocks because
every aligned allocation would create a tiny hole, and
secondly the lmb_reserve() call there did not have it's
return value checked.
Powerpc folks, if there are no objections please pull, thanks!
The following changes since commit 96b5a46e2a72dc1829370c87053e0cd558d58bc0:
Linus Torvalds (1):
WMI: initialize wmi_blocks.list even if ACPI is disabled
are available in the git repository at:
master.kernel.org:/pub/scm/linux/kernel/git/davem/lmb-2.6.git master
David S. Miller (2):
[LIB]: Make PowerPC LMB code generic so sparc64 can use it too.
[LMB]: Fix bug in __lmb_alloc_base().
