equal to mem=nn[KMG], update it too here.
And for memmap=nn[KMG]$ss[KMG], escape character need be added before
'$' for some bootloaders. E.g in grub2, if specified memmap=100M$5G,
actually it passed memmap=100MG to kernel.

am not very sure why this is introduced, number of possible cpu is
decided by the min value of nr_cpus= and possible_cpus=.
nr_cpus and maxcpus might not be very clear to people which are
described in Documentation/kernel-parameters.txt.
Hi Jon, do you think change as below is OK to you?

This patch is clearly related to kdump. The prefix of subject should be
changed to kdump. Kexec doesn't need to handle vmcore things.
And patches realted to kexec/kdump should be CCed to Andrew, he usually
picks up and add them into akpm tree.
Hi Pratyush,
Could you please help tell why arm
