[PATCH] paravirt_ops x86_64 , take 2
...places in which macros were replaced by functions, and
the arguments happened to mismatch types.
* calling paravirt_ops functions from .S files (I lacked this last time)
* addition of the startup_paravirt function, to kick off guests (not
tested)
* fixed problems with patching
* added a new field, vsyscall_page in the paravirt_ops struct, which
allows the kernel to map a vsyscall_page on its own
* fixed vsyscall functions to avoid calling paravirt_ops functions.
__vsyscall_0 is the page to be mapped for the host. (set and get cpu not
yet tested.)
* fixed cpuid calls.
* added substitute for the swapgs ins...
