Component Type: kbuild config
Description: Allocate 2nd-level pagetables from highmem
More info: The VM uses one page of physical memory for each page table. For systems with a lot of processes, this can use a lot of precious low memory, eventually leading to low memory being consumed by page tables. Setting this option will allow user-space 2nd level page tables to reside in high memory.
