please check updated for-x86-mm branch.
[PATCH -v4 00/15] x86: Use BRK to pre mapping page table to make xen happy
on top of current linus/master and tip/x86/mm2, but please zap last
patch in that branch.
1. use brk to mapping first PMD_SIZE range.
2. top down to initialize page table range by range.
3. get rid of calculate page table, and find_early_page_table.
4. remove early_ioremap in page table accessing.
v2: changes, update xen interface about pagetable_reserve, so not
use pgt_buf_* in xen code directly.
v3: use range top-down to initialize page table, so will not use
calculating/find early table anymore.
also reorder the patches sequence.
v4: add mapping_mark_page_ro to fix xen, also move pgt_buf_* to init.c
and merge alloc_low_page()
