[PATCH -v2 00/10] x86: Use BRK to pre mapping page table to make xen happy

[Yinghai Lu]

on top of tip/x86/mm2

1. use brk to mapping final page table
2. remove early_ioremap in page table accessing.

v1-v2: changes, update xen interface about pagetable_reserve, so not
   use pgt_buf_* in xen code directly.
