x86: remove redundancy of MSR_P6_{PERFCTR,EVNTSEL} definitions

Not only did the EVNTSEL ones get defined twice, we can also easily
abstract out the numbers previously attached to them.

While at it also remove an unused Geode-related define.

xen: vnuma topology and subop hypercalls

Define interface, structures and hypercalls for toolstack to
build vnuma topology and for guests that wish to retrieve it.
Two subop hypercalls introduced by patch:
XEN_DOMCTL_setvnumainfo to define vNUMA domain topology per domain
and XENMEM_get_vnumainfo to retrieve that topology by guest.

libxc: Introduce xc_domain_setvnuma to set vNUMA

With the introduction of the XEN_DOMCTL_setvnumainfo
in patch titled: "xen: vnuma topology and subop hypercalls"
we put in the plumbing here to use from the toolstack. The user
is allowed to call this multiple times if they wish so.
It will error out if the nr_vnodes or nr_vcpus is zero.

xl: convert vcpuid to signed in main_vcpupin()

As it needs to be, considering that we assign -1 to it (and

While at it, fix a coding style nit and improve error reporting.

tools/libxl: Fix build of libxl with ./configure --disable-blktap2

Autoconf already has appropriate Linux/non-Linux logic for CONFIG_BLKTAP2.

Let LIBXL_BLKTAP inherit directly from CONFIG_BLKTAP2, rather than requiring a
further LIBXL_BLKTAP=n in addition to ./configure --disable-blktap2 to get
libxl to successfully link under Linux.
