Subject[PATCH v4 00/11] Hyper-V: Support PAGE_SIZE larger than 4K
Date
This patchset add the necessary changes to support guests whose page
size is larger than 4K. And the main architecture which we develop this
for is ARM64 (also it's the architecture that I use to test this
feature).

Previous version:
v1: https://lore.kernel.org/lkml/20200721014135.84140-1-boqun.feng@gmail.com/
v2: https://lore.kernel.org/lkml/20200902030107.33380-1-boqun.feng@gmail.com
v3: https://lore.kernel.org/lkml/20200910143455.109293-1-boqun.feng@gmail.com/

Changes since v3:

* Fix a bug that ringbuffer sizes are not page-aligned when
PAGE_SIZE = 16k. Drop the Acked-by and Reviewed-by tags for
those patches accordingly.

* Code improvement as per suggestion from Michael Kelley.

I've done some tests with PAGE_SIZE=64k and PAGE_SIZE=16k configurations
on ARM64 guests (with Michael's patchset[1] for ARM64 Hyper-V guest
support), everything worked fine ;-)

Looking forwards to comments and suggestions!

Regards,
Boqun
