Subject: Re: [PATCH 4/4] x86 paravirt_ops: binary patching infrastructure

And a trivial warning fix on that last one when !CONFIG_PARAVIRT.

struct paravirt_patch is only defined for CONFIG_PARAVIRT, so we
declare the (unused) __start and __stop section markers as char, which
causes a warning when we pass them to the dummy apply_paravirt.
