[PATCH v3] Clear IRQ_GUEST in irq_desc->status when setting action to NULL.
Looking more closely at usage of action field with relation to
IRQ_GUEST flag. It appears that set IRQ_GUEST implies that action
is not NULL. As result it is not safe to set action to NULL and
leave IRQ_GUEST set.
Hence IRQ_GUEST should be cleared in dynamic_irq_cleanup where
action is set to NULL.
An addition remove BUGON at __pirq_guest_unbind that appears to be
bogus and not needed anymore.
Thanks Paolo Bonzini for NACKing previous patch, and pointing at the
correct solution.
Please review.

[PATCH 0 of 4] Prune outdated/impossible preprocessor symbols, and update VIOAPIC emulation
Patch 1 removes CONFIG_SMP
Patch 2 removes separate smp_{,r,w}mb()s as a result of patch 1
Patch 4 removes __ia64__ defines from the x86 arch tree
Patch 3 is related to patch 4 and changes the VIOAPIC to emulate
version 0x20 as a performance gain. It preceeds Patch 4 so as to be
more clear about the functional change.

[PATCH 00 of 38] xen: add more Xen dom0 support
Hi Ingo,
Here''s the chunk of patches to add Xen Dom0 support (it''s probably
worth creating a new xen/dom0 topic branch for it).
A dom0 Xen domain is basically the same as a normal domU domain, but
it has extra privileges to directly access hardware. There are two
issues to deal with:
- translating to and from the domain''s pseudo-physical addresses and
real machine
