Subject: [PATCH v2 0/2] block/xen-blkfront: Support non-indirect grant with 64KB page granularity

Hi all,

This is a follow-up on the previous discussion [1] related to guest using 64KB
page granularity which doesn't boot when the backend isn't using indirect
descriptor.

This has been successfully tested on ARM64 with both 64KB and 4KB page
granularity guests and QEMU as the backend. Indeed QEMU doesn't support
indirect descriptor.

This series is based on xentip/for-linus-4.4 which include the support for
64KB Linux guest.

For all the changes see in each patch.

Sincerely yours,

[1] http://lists.xen.org/archives/html/xen-devel/2015-08/msg01659.html
