entry: KVM: Allow use of generic KVM entry w/o full generic support

mainline inclusion
from mainline-v5.14
commit e1c6b9e1
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4VZJT
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e1c6b9e1669e44fb7f9688e34e460b759e3b9187



--------------------------------

Some architectures (e.g. arm64) have yet to adopt the generic entry
infrastructure. Despite that, it would be nice to use some common
plumbing for guest entry/exit handling. For example, KVM/arm64 currently
does not handle TIF_NOTIFY_PENDING correctly.

Allow use of only the generic KVM entry code by tightening up the
include list. No functional change intended.
