x86_64: Quicklist support for x86_64
This adds caching of pgds and puds, pmds, pte. That way we can avoid costly
zeroing and initialization of special mappings in the pgd.
A second quicklist is useful to separate out PGD handling. We can carry the
initialized pgds over to the next process needing them.
Also clean up the pgd_list handling to use regular list macros. There is no
need anymore to avoid the lru field.
Move the add/removal of the pgds to the pgdlist into the constructor /
destructor. That way the implementation is congruent with i386.
