[Qemu-devel] [PATCH v1 2/7] kvm: fix alignment of ram address |
Date: |
Mon, 16 Oct 2017 16:42:57 +0200 |
Fix the wrong calculation of the delta, used to align the ram address.
This only strikes if alignment has to be done.
Reported-by: Joe Clifford <address@hidden>
Fixes: 5ea69c2e3614 ("kvm: factor out alignment of memory section")
