[Xen-devel] [PATCH v4 7/7] x86: expose CONFIG_HVM

[Wei Liu <wei.liu2@xxxxxxxxxx>]

v4: remove a blank line
v3: longer text
v2: use tab to indent

Haven't added a dependency on PV_SHIM_EXCLUSIVE because agreement is
not yet reached.

CC more people for opinions.

I don't have an opinion here, that's why I didn't reply to previous
threads.

Maybe

  def_bool y if !PV_SHIM_EXCLUSIVE

is a good compromise?
