// Library support to remap process executable elf segment with hugepages.
// InitHugepagesAndMlockSelf() will search for an ELF executable segment,
// and remap it using hugepage.

// This function will scan ELF segments and attempt to do two things:
// - Reload some of .text into hugepages
// - Lock some of .text into memory, so it can't be swapped out.
// When this function returns, text segments that are naturally aligned on
// hugepage size will be backed by hugepages.
// Any and all errors encountered by this function are soft errors; Chrome
// should still be able to run.
