Re: [Xen-ia64-devel] [PATCH][RFC] Introduce xen specific gate page.

[Alex Williamson <alex.williamson@xxxxxx>]

Hi Isaku,

   This looks like a good idea, a few questions:

      * Is there still a need to keep the CONFIG_XEN_IA64_VDSO_PARAVIRT
        sub config option?  Would we actually support this not set, or
        should we merge it into CONFIG_XEN?
      * If I understand correctly, instead of creating a single, dynamic
        bare metal/paravirt gate page, this is creating two static pages
        and the appropriate one is installed once at boot.  Is the other
        one freed?
      * The calculated padding using the .skip looks like a bit of a
        maintenance issue (not that these files change often), could it
        be calculated at build time?
      * Does this simplify any aspect of the paravirt_alt proposal?  I
        don't think so, but I'd like to know your plans for that as
        well.

Thanks,

        Alex
