Re: [Xen-devel] PATCH: console.c: use ioremap instead of __va to map vid

No, it got removed as it wasn't used, but it can easily be added back.
It's particularly easy since we probably don't need iounmap().
Hmm, looking at the hg logs, it looks like ioremap() was added for
x86-64 with the current __va() implementation. Can you please point me
at the old version?
If you want the old ioremap(), see for example changeset 1452, and look
for xen/arch/i386/ioremap.c. That implementation would still work even
for x86/64 -- the bit that directly changes page tables should actually
call map_pages_to_xen().
