[Xen-devel] RFC: xencomm in common

[Tristan Gingold <Tristan.Gingold@xxxxxxxx>]

Hi,

xencomm is the ppc infrastructure to do hypercalls with guest physical 
addresses instead of virtual address.

Because ia64 should also use physicall address, I think it's better to re-use 
the ppc code and to put into common code.

I'd propose to submit this patch is every part is OK (ie no NAK).

This patch creates include/xen/xencomm_access.h which is to be included by 
asm/guest_access.h.  It also creates common/xencomm.c which is compiled only 
if HAS_XENCOMM is y in Rules.mk.

Arch using xencomm should defines a few arch-specific macros and function.

I will submit the linux side soon.

Tristan.
