[Xen-devel] [PATCH 0 of 4] Prune outdated/impossible preprocessor symbols, and update VIOAPIC emulation

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

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.
