When xm block-detach command was done on PV-ON-HVM, the response of
other disks was lost. It is because a wrong event channel was
invalidated when detaching it. Not the evtchn number but the irq
number is invalidated specifying it.

- The adjustments to README and overrides.mk are generic.
- The removal of explicit linux/config.h inclusion should also not
cause any issues.
- The introduction of irq_handler_t should eliminiate warnings on
2.6.19+ kernels (I didn't check they're there, but since the
request_irq prototype changed, I'm sure there's at least
one. However, as a result changes to the Linux tree are expected to
be required.
- The change setup_xen_features -> xen_setup_features follows the
naming in mainline 2.6.23 but would apparently also require changes
to the Linux tree.
- The changes SA_* -> IRQF_ and pci_module_init ->
pci_register_driver should also not cause issues.

smp_call_function() compiles to nothing on non-SMP, so we had a
defined-but-not-used static function.

This patch adds missing includes that currently work through indirect
inclusions. This cannot be relied on and indeed does break on older
kernels (2.4 for PV-on-HVM).

after balloon operations in an HVM guest.
This removes the I/O port hack from the guest OS, and from ioemu.
Also we flush on reservation *increases* as well as decreases. This is
necessary until qemu-dm can demand-fault page mappings into existing
valid buckets.

The HVM guest did not respond when PV-on-HVM driver was tested on
the following conditions.
1. RHEL4u4
2. vcpu 4
3. irqbalance on
4. pv-on-hvm driver used.
Eventhandler did not work because IRQ was delivered to another vcpu by
irqbalance.

Add a ctrl_alt_del() implemenation to the PV on HVM compatibility
layer since ctrl_alt_del() is not exported on native kernels.

- some cleanup to mkbuildtree
- adjustment to the fake __supported_pte_mask definition (removing the
export for x86-64 in native Linux is being discussed, so this shouldn't be
i386 specific)
- remove odd/unused defines (mostly CONFIG_*) in overrides.mk

kasprintf has been merged upstream with a slightly different protoype
