Subject: [GIT PULL tip/x86/mm] xen/x86 fixes

Hello,
recently we had a couple of long discussions with Yinghai about boot
crashes on xen, related to pagetable initialization.
As a result we came up with three patches, two of them fix the first [1]
boot crash and provide a nice cleanup on native:


Stefano Stabellini (1):
      xen: set max_pfn_mapped to the last pfn mapped
Yinghai Lu (1):
      x86: Cleanup highmap after brk is concluded


The third is a xen patch that fixes the other boot crash [2], indirectly
caused by the new initial kernel pagetable allocation strategy:


Stefano Stabellini (1):
      xen: update mask_rw_pte after kernel page tables init changes


I have put together a branch with these three patches, based on
tip/x86/mm:

git://xenbits.xen.org/people/sstabellini/linux-pvhvm.git 2.6.38-tip-fixes

Could you please pull from it?
