xen_pfn_t? Definitely won't conflict with anyone, and I prefer 'pfn' to
'frameno' as it's more consistent with other names we have in the
interface.
why not xen_mfn_t? Is "p" here for "page" or "physical"? using
"m" makes it a bit more explicit.
Attached is the updated patch, with typos fixed and a couple other
corrections. I've also added the type to arch-x86_64.h and arch-ia64.h,
so I think the patch is ready to be applied.
What about the Linux kernel -- shouldn't that be changed too? At least
where it handles arrays of longs passed to memory_op()?
Inside Xen, does shadow.h really need changing at all? Once entries are
unpacked from an array by a hypercall they could just be passed round as
longs, right?
Sorry about the to'ing-and-fro'ing but we need to make sure interface
changes are complete and correct and this one is inevitably pretty
far-reaching.
