Maintain back mapping from irqchip/pin to gsi to speedup
interrupt acknowledgment notifications.

Implement KVM_IA64_VCPU_[GS]ET_STACK ioctl calls. This is required
for live migrations.
Patch is based on previous implementation that was part of old
GET/SET_REGS ioctl calls.

This rips out the support for KVM_DEBUG_GUEST and introduces a new IOCTL
instead: KVM_SET_GUEST_DEBUG. The IOCTL payload consists of a generic
part, controlling the "main switch" and the single-step feature. The
arch specific part adds an x86 interface for intercepting both types of
debug exceptions separately and re-injecting them when the host was not
interested. Moveover, the foundation for guest debugging via debug
registers is layed.
To signal breakpoint events properly back to userland, an arch-specific
data block is now returned along KVM_EXIT_DEBUG. For x86, the arch block
contains the PC, the debug exception, and relevant debug registers to
tell debug events properly apart.
The availability of this new interface is signaled by
KVM_CAP_SET_GUEST_DEBUG. Empty stubs for not yet supported archs are
provided.
Note that both SVM and VTX are supported, but only the latter was tested
yet. Based on the experience with all those VTX corner case, I would be
fairly surprised if SVM will work out of the box.

Kconfig symbols are not available in userspace, and are not stripped by
headers-install. Avoid their use by adding #defines in <asm/kvm.h> to
suit each architecture.

fix the following 'make headers_check' warnings:
usr/include/asm-ia64/kvm.h:24: include of <linux/types.h> is preferred over <asm/types.h>
usr/include/asm-ia64/kvm.h:34: found __[us]{8,16,32,64} type without #include <linux/types.h

Fix kvm_arch_vcpu_ioctl_[gs]et_regs() to do something meaningful on
ia64. Old versions could never have worked since they required
pointers to be set in the ioctl payload which were never being set by
the ioctl handler for get_regs.
In addition reserve extra space for future extensions.
The change of layout of struct kvm_regs doesn't require adding a new
CAP since get/set regs never worked on ia64 until now.
This version doesn't support copying the KVM kernel stack in/out of
the kernel. This should be implemented in a seperate ioctl call if
ever needed.

After moving the the include files there were a few clean-ups:
1) Some files used #include <asm-ia64/xyz.h>, changed to <asm/xyz.h>
2) Some comments alerted maintainers to look at various header files to
make matching updates if certain code were to be changed. Updated these
comments to use the new include paths.
3) Some header files mentioned their own names in initial comments. Just
deleted these self references.
