Xen crash on dom0 shutdown
There is a BUG_ON() at xen/arch/x86/physdev.c:169 which appears to
be dependent upon guest behavior (should close event channel before
un-mapping pirq), rather than on internal hypervisor state. In 2.6.18,
this likely goes unnoticed because pci_device_shutdown() only calls all
the driver shutdown routines. In newer kernels, however, it also calls
pci_msi_shutdown() and pci_msix_shutdown(), which

[PATCH 0/3] x86: adjust entry frame generation
This set of patches converts the way frames gets created from
using PUSHes/POPs to using MOVes, thus allowing (in certain
cases) to avoid saving/restoring part of the register set.
While the place where the (small) win from this comes from varies
between CPUs, the net effect is a 1 to 2% reduction on a
combined interruption entry and exit when the full state save
can be avoided.
