Here're a couple of patches that introduce a Kconfig control for user to be
able to remove nested HVM code from the build and hence to tune their system
in case nested VMs aren't required.
The first two patches are minor fixes and not directly related to nested HVM,
but since they also modify the same code I've decided to include them too.

x86:svm: use nsvm_efer_svm_enabled() to check guest's EFER.SVME
x86:svm: rename svm/nestedhvm.h -> svm/nestedsvm.h
x86:hvm: guard calls to nestedhvm routines
x86:hvm: make nestedhvm support optional
