Emmanuel Ackaouy 81665f8e30 [XEN] [TOOLS] 32on64 compat save/restore: unadjust L3E flags at save time 
Get rid of USER|RW|ACCESSED L3 PTE flags which may be present
in a PAE guest when running on a 64bit hypervisor at save time.
This prevents the restore operation from getting confused by
these flags.
Reset disallowed L3E flags to match PAE case.

kfraser@localhost.localdomain 6a20532c7b alloc_boot_pages() allocates downwards from high memory. 
This conserves low memory.

Provide new function alloc_boot_low_pages() for those callers who
actually require lowmem pages (e.g., below 4GB).

kfraser@localhost.localdomain 92eb4bd779 x86: Detect shadow-emulate write to stack from inside the write 
handler, where we can quite conveniently check whether the access
segment is SS. This will only give a false positive for non-stack
writes that override the destination segment to SS, which it is
probably safe to assume will never happen when the destination is a
legitimate page table!

For now, instead of bailing and unshadowing just increment a perfctr
and we'll see if that increases fast under any reasonable workload.
