IB/srp: Skip host settle delay
The SRP initiator implements host reset by reconnecting to the SRP
target. That means that communication with the target is possible as
soon as host reset finished. Hence skip the host settle delay.

IB/srp: Avoid skipping srp_reset_host() after a transport error
The SCSI error handler assumes that the transport layer is operational
if an eh_abort_handler() returns SUCCESS. Hence srp_abort() only
should return SUCCESS if sending the ABORT TASK task management
function succeeded. This patch avoids the SCSI error handler skipping
the srp_reset_host() call after a transport layer error.

drm: add hotspot support for cursors.
So it looks like for virtual hw cursors on QXL we need to inform
the "hw" device what the cursor hotspot parameters are. This
makes sense if you think the host has to draw the cursor and interpret
clicks from it. However the current modesetting interface doesn't support
passing the hotspot information from userspace.
This implements a new cursor ioctl, that takes the hotspot info as well,
userspace can try calling the new interface and if it gets -ENOSYS it means
its on an older kernel and can just fallback.
