hulk inclusion category: feature bugzilla: 48159 CVE: N/A
------------------------------
reserve_crashkernel or reserve_quick_kexec may find one sutiable memory region and reserves it, which address of the region is not fixed.
As a result, cpu park reserves memory could be failed while specified address used by crashkernel or quickkexec.
So, move reserve_park_mem before reserve_crashkernel and reserve_quick_kexec.
