+ debug_pagealloc=
+ [KNL] When CONFIG_DEBUG_PAGEALLOC is set, this

+ chunk of memory for debug pagealloc if we don't enable
+ it at boot time and the system will work mostly same

huge pages of different sizes. Valid pages sizes on
x86-64 are 2M (when the CPU supports "pse") and 1G

- Note that 1GB pages can only be allocated at boot time
- using hugepages= and not freed afterwards.
