Subject: [GIT]: Make LMB code sharable with sparc64.
Date: Wed, 13 Feb 2008 00:41:20 -0800 (PST)	[thread overview]
Message-ID: <20080213.004120.22092044.davem@davemloft.net> (raw)


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().
