To make it easier, I made a branch called
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/bug-fixes-for-rc6
that has all the right magic sauce in it:
Konrad Rzeszutek Wilk (1):
Revert "xen/mmu: Add workaround "x86-64, mm: Put early page table high""
Sedat Dilek (1):
x86/mm: Fix section mismatch derived from native_pagetable_reserve()
Stefano Stabellini (1):
x86,xen: introduce x86_init.mapping.pagetable_reserve
