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

[Julien Grall]

Hi all,

This is a follow-up on the previous discussion [1] related to guest using 64KB
page granularity not booting with backend using non-indirect grant.

This has been successly tested on ARM64 with both 64KB and 4KB page granularity
guests and QEMU as the backend. Indeed QEMU is not supported indirect.

For a summary of the previous discussion see patch #2.

This series is based on top of my 64KB page granularity support [2].

Comments are welcomed.

Sincerely yours,
