[PATCH 0/2] powerpc/kexec: automatically allocating mem for crashkernel=Y

If no start address is specified for crashkernel, the current program hard
code as: crashk_res.start = min(0x8000000ULL, (ppc64_rma_size / 2));
This limits the candidate memory region, and may cause failure while there
is enough mem for crashkernel. This patch suggests to find a suitable mem
chunk by memblock_find_in_range()
