This series of patches converts the PowerPC ieee1275 memory allocator
for kernel and initrd to use the (PowerPC) regions_claim memory allocator
that takes into account memory regions that are not allowed to be used,
such as the gap between 640MB and 768MB as well as memory regions beyond
an address in case an fadump is present. Otherwise those two could be
loaded into restricted memory regions and either cause a crash or
corruption of the fadump.
I adjusted the kernel and initrd load in loader/powerpc/ieee1275 to use the
new memory allocator only on PowerVM and PowerKVM since this code is shared
with other platforms, such as old PowerMACs.
I have sent you some more comments. Mostly nits. If you take them into
account feel free to add my RB to all patches.
