clean up of xencomm.c. is_phys_contiguous() is arch dependent function that depends on how virtual memory are laid out. So split out the function into arch specific code. Signed-off-by: Isaku Yamahata <yamahata at valinux.co.jp> Cc: "Luck, Tony" <tony.luck at intel.com> --- drivers/xen/xencomm....

On ia64/xen, pointer argument for the hypercall is passed by pseudo physical address (guest physical address.) So it is necessary to convert virtual address into pseudo physical address right before issuing hypercall. The frame work is called xencomm. This patch implements arch specific part.

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...

Hi, taking into account Hollis comments I now submit this patch. IA64 specific stuff will be posted to xen-ia64-unstable after merge. Tristan. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
