Revision 887349f69f37e71e2a8bfbd743831625a0b2ff51 authored by Michael S. Tsirkin on 28 February 2016, 15:35:59 UTC, committed by Ralf Baechle on 29 February 2016, 14:52:20 UTC
Calling return copy_to_user(...) or return copy_from_user in an ioctl will not do the right thing if there's a pagefault: copy_to_user/copy_from_user return the number of bytes not copied in this case. Fix up kvm on mips to do return copy_to_user(...)) ? -EFAULT : 0; and return copy_from_user(...)) ? -EFAULT : 0; everywhere. Signed-off-by: Michael S.
