When invalidating memory ranges, if we happen to hit the first
entry in a bucket we were never unmapping it. This was harmless
for foreign mappings but now that we're looking to reuse the
mapcache for transient grant mappings, we must unmap entries
when invalidated.

The current check used in fixup_irqs() to decide whether to move around
interrupts is based on the affinity mask, but such mask can have all bits set,
and hence is unlikely to be a subset of the input mask. For example if an
interrupt has an affinity mask of all 1s, any input to fixup_irqs()

When the revision in hardware is newer than anything Xen has to hand,
'microcode_cache' isn't set up. Then, `xen-ucode` initiates the update
because it doesn't know whether the revisions across the system are symmetric
or not. This involves the patch getting all the way into the
From: Petr Beneš
This commit introduces the ability to configure the maximum number of altp2m
views for the domain during its creation. Previously, the limits were hardcoded
to a maximum of 10. This change allows for greater flexibility in environments
that require more or fewer altp2m views.
From: Petr Beneš
Allow developers using the OCaml bindings to set the altp2m_count parameter.
