[Xen-devel] [PATCH v2 8/9] x86/HVM: reduce hvm.h include dependencies

[Jan Beulich <jbeulich@xxxxxxxx>]

Drop #include-s not needed by the header itself, and add smaller scope
ones instead. Put the ones needed into whichever other files actually
need them.

Signed-off-by: Jan Beulich <jbeulich@xxxxxxxx>

v2: Also make things build with PV_SHIM_EXCLUSIVE=y.
