It may be desirable to change Xen's PAT for various reasons. This
requires changes to several _PAGE_* macros as well. Add static
assertions to check that XEN_MSR_PAT is consistent with the _PAGE_*
macros, and that _PAGE_WB is 0 as required by Linux.

Changes since v2:
get_page_from_l1e() relied on Xen's choice of PAT, which is brittle in
the face of future PAT changes. Instead, compute the actual cacheability
used by the CPU and switch on that, as this will work no matter what PAT
Xen uses.
No functional change intended. This code is itself questionable and
These are not currently used, so there is no functional change. Future
patches will use these constants.

This is a preparatory step in order to do earlier microcode loading on
the boot CPU when the domain heap has not been initialized yet and
xmalloc still unavailable.
Add make_copy argument which will allow to load microcode directly from
the blob bypassing microcode_cache.

Call early_microcode_init() straight after multiboot modules become

populating microcode_cache because xmalloc is still not available at
that point during Xen boot.
Introduce early_microcode_init_cache() for populating

At the moment, for dom0less domUs, we do not have a way to specify
per domain grant table related limits (unlike when using xl), namely
max version, max number of grant frames, max number of maptrack frames.
This means that such domains always use the values specified by the Xen
command line
