Subject: [PATCH 0/11] Another set of nested svm fixes and optimizations

Hi,

here is another set of patches I collected in the last days while trying
to get Hyper-V running with nested svm. I was not successful yet but the
patches in this set make sense anyway :-)
The patches fix coding style issues which annoyed me for some time
because my vim shows all c-space-errors with red color. Other patches in
this set make nested svm more complete (nmi and selective cr0 related).
The vm_cr and hwcr.ignne patches are related to Hyper-V tests. This
hypervisor expects to write to those msrs.
The most interesting thing is patch 11 which reduces the amount of
memory which is touched in the vmrun emulation for merging the msrpms
from 24kb to 48 bytes.  Please review and comment (or apply if
perfect ;-) ) these patches.

Thanks,

	Joerg
