[PATCH 0/3] blktap: various clean up and ia64 support

[Isaku Yamahata]

Hi. This patch set is for blktap support on IA64.
I'm aware of zap_page_range() discussion, but I didn't
address it at this time.

Xen/IA64 adopts VP (Virtual Physical) model(i.e. it fully virtualize MMU)
so that GNTMAP_application_map and GNTMAP_contains_pte doesn't make sense.
Instead, blktap driver calls vm_insert_pages() and zap_page_range().
I used "if (xen_feature(XENFEAT_auto_translated_physmap))" instead of
"#ifdef __ia64__" like blkback, netback.

[PATCH 1/3] blktap various clean up
[PATCH 2/3] blktap mb fixes
[PATCH 3/3] blktap ia64 support


Thanks

Hi Isaku,

I tested this today on rx2600 (2x Madison).  It's working very well!
Thanks a lot for working on this.

Also, here is the patch to enable blktap by default in the xen/ia64
buildconfigs.

Regards,
Aron

Hi Keir,

Is something keeping Isaku's blktap/ia64 patches from xen-unstable?
We need these in RHEL5 but I'd like to see them merged into
xen-unstable before patching the distro.

Thanks,
Aron

I'm not really blktap maintainer. Andy or Julian should probably look at the
patches.
