Introduce kvm_cpuid() to perform the leaf limit check and calculate
register values, and let kvm_emulate_cpuid() just handle reading and
writing the registers from/to the vcpu. This allows us to reuse
kvm_cpuid() in a context where directly reading and writing registers
is not desired.

There were some missing pieces for trying this patch series.
Firstly, the patch is for v3.5-rc4, but that version has an issue
that it cannot passthrough PCI devices because of genirq changes.

A new module named vmcsinfo-intel is used to fill VMCSINFO. And
this module depends on kvm-intel and kvm module. So we should
export some symbols of kvm-intel and kvm module that are needed
by vmcsinfo-intel.

Allow CROSS_COMPILE to be used to prefix CC as is done in the kernel
Makefile. If CROSS_COMPILE is unset it has no effect, and still allows
CC to be overridden.
We need to fix a few places to use ARCH instead of uname_M directly, so
that the overridden setting of ARCH takes effect.
Signed-off-by:
The sed expression for ARCH seems to have been cribbed from the top-level
kernel Makefile, and includes lots of architectures kvmtool doesn't
support - strip it down.
Also call uname -m directly there and get rid of uname_M.

Please also implement a ONE_REG interface while at it. Over time, I'd like to

I think this code was based on an earlier version of the KVM_SET_ONE_REG
API, which at the time was in agraf's tree but not mainline?
Either way it doesn't compile as is, so fix it up.

The SGL memory allocated during vhost_scsi_map_iov_to_sgl() setup was never
getting freed during tv_cmd completion -> release path. Fix this up by
releasing
tv_cmd->tvc_sgl in vhost_scsi_free_cmd() ahead of tv_cmd descriptor free.
