[GIT PULL] x86/kdump for 7.4-rc1

[Dave Hansen]

Hi Linus,

Please pull some x86/kdump changes for 7.4-rc1. Some kdump code is
using NR_CPUS_DEFAULT as if it were the actual, in-use max number of
CPUs. Move it over to use NR_CPUS instead.

I suspect this one being in-tree for a few years means that the vast
majority of kdump users are on distro kernels that don't drop NR_CPUS
below the defaults.
