On some actitectures the physical memory can be 64 bits, therefore
the code that reads proc entries needs to take into account it could
read either a 32 bit or 64bit value for the physical addresses.

This fixes --reuseinitrd and --ramdisk option for ppc32 on
uImage-ppc and Elf. It works for normal kexec as well as for
kdump.
When using --reuseinitrd you need to specifify retain_initrd
on the command line. Also, if you are doing kdump you need to make
sure your initrd lives in the crashdump reg
Currently, the device tree is passed as is. You can optionally
update the command line and specifically listed nodes but nothing
is updated automatically.
This patch updates the memreserve regions, memory node, initrd
nodes and attempts to make the device tree look as it should. Some
code is borro

Hello All,
I'm trying to bring up a Marvell board [db644xx] with dual CPU[7447A]
with kernel 2.6.33.5-rt23[Ingo's RT patch]. For conveniance I have
registered IPI interrupt with IRQF_NODELAY flag, all other interrupts are
threaded. I'm able to boot up the system fine, however after few hours I

Update the memory sysfs code that each sysfs memory directory is now
considered a memory block that can contain multiple memory sections per
memory block. The default size of each memory block is SECTION_SIZE_BITS
to maintain the current behavior of having a single memory section per
memory block
Add a section count property to the memory_block struct to track the number
of memory sections that have been added/removed from a memory block. Updated
to use atomic_dec_and_test().

Update the 'phys_index' properties of a memory block to include a
'start_phys_index' which is the same as the current 'phys_index' property.
This also adds an 'end_phys_index' property to indicate the id of the
last section in th memory block.
Patch updated to keep the name of the phys_index prope
