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 Kcon

If we add to an empty lmb region with a non-zero base we will not coalesce
the number of regions done to one. This causes problems on ppc32 for the
memory region as its assumed to only have one region.
We can fix this be easily specially casing the initial add to just replace
the dummy region.

This patch adds kdump support to the ehea driver. As the firmware doesn't free
resource handles automatically, the driver has to run an as simple as possible
free resource function in case of a crash shutdown. The function iterates over
two arrays freeing all resource handles which are stored there

Hi,
the following two patches prevent kernel from crashing on powerpc.
The surrounding ifdefs will be obsolete, if check_legacy_ioport becomes
generic code.

This patch adds a check_legacy_ioports to read_port and write_port.
It will now return ENXIO, instead of oopsing.

when probing i2c-pca-isa writes to legacy ioports, which crashes the kernel
if there is no device at that port.
This patch adds a check_legacy_ioport call, so probe failes gracefully
and thus prevents the oops.

Publish the devices listed in dts under SOC as of_device for mpc85xx_cds
platforms.
The memory controller, L2 cache-controller, and the PCI controller(s) are
published as of_device so the mpc85xx EDAC driver can claim them for usage.

Convert the lmb code to use phys_addr_t instead of unsigned long for

2) Fix potential build errors wrt. asm/prom.h dependencies.
arch/powerpc/platforms/cell/ras.c still has DEBUG #defined, which is no
longer neccessary. Disable it, this disables to pr_debugs().
