We have been enforcing host page alignment for the non-R
fallback of MAX_RESERVED_VA, but failing to enforce for -R.

Pass the address of the last byte to be changed, rather than
the first address past the last byte. This avoids overflow
when the last page of the address space is involved.

Fixes a bug in the loop comparision where "<= end" would lock
one more page than required.

In addition to the rename, change the semantics to be the
last byte of the guest va, rather than the following byte.
This avoids some overflow conditions.

The primary issue is that of overflow, where "end" for the last
page of the 32-bit address space overflows to 0. The fix is to
use "last" instead, which can always be represented.

Unfortunately a bug in older versions of gdb means that they will
crash if QEMU sends them the aarch64-pauth.xml. This bug is fixed in
gdb commit 1ba3a3222039eb25, and there are plans to backport that to

The dependencies between the CRS entries and bus numbers due to
PCI eXpander Bridges taking resources from the primary bus make this
a slightly complex dance.
The rules we have to fit into are:
1) FACP is first table in RSDT and points to the DSDT.
