'mem=" option is an easy way to put high pressure on memory during some
test. Hence after applying the memory limit, instead of total mem, the
actual usable memory should be considered when reserving mem for
crashkernel. Otherwise the boot up may experience OOM issue.

E.g. it would reserve 4G prior to the change and 512M afterward, if passing
crashkernel="2G-4G:384M,4G-16G:512M,16G-64G:1G,64G-128G:2G,128G-:4G", and
mem=5G on a 256G machine.

[...]

Applied to powerpc/next.
