Message-ID: <20210805212616.2641017-1-farosas@linux.ibm.com> (raw)

This series contains the fix for __kvmhv_copy_tofrom_guest_radix plus
a couple of changes.

- Patch 1: The fix itself. I thought a smaller fix upfront would be
           better to facilitate any backports.

- Patch 2: Adds a sanity check to the low level function. Since the
           hcall API already enforces that the effective address must
           be on quadrant 0, moving the checks from the high level
           function would only add overhead to the hcall path, so I
           opted for a lightweight check at the low level.

- Patch 3: Cleans up the EXPORT_SYMBOL_GPL tags. I don't see how they
           would be needed since the functions are contained within
           kvm-hv.ko.
