well there are context dependencies so i've put them into x86/xen-64bit.

i picked up these four and merged them into tip/master:

Jeremy Fitzhardinge (4):
      x86_64/setup: unconditionally populate the pgd
      x86: always set _PAGE_GLOBAL in _PAGE_KERNEL* flags
      x86_32: remove __PAGE_KERNEL(_EXEC)
      x86/cpa: use an undefined PTE bit for testing CPA

the others were either already applied or didnt apply.

i'm still testing tip/master but i've pushed out these updates to 
x86/xen-64bit - you should be able to get the tree i'm testing by doing:

   git-checkout tip/master
   git-merge tip/x86/xen-64bit
