Both ceph_sync_direct_write and ceph_sync_read iterate iovec elements
one by one, send one OSD request for each iovec. This is sub-optimal,
We can combine serveral iovec into one page vector, and send an OSD
request for the whole page vector.

create_request_message() computes the maximum length of a message,
but uses the wrong type for the time stamp: sizeof(struct timespec)
may be 8 or 16 depending on the architecture, while sizeof(struct
ceph_timespec) is always 8, and that is what gets put into the
message.
Found while auditing the uses of timespec for y2038 problems.

Pull memremap fix from Dan Williams:
"The new memremap() api introduced in the 4.3 cycle to unify/replace
ioremap_cache() and ioremap_wt() is mishandling the highmem case.
This patch has received a build success notification from a
0day-kbuild-robot run and has received an ack from Ard"

"The impact of this bug is low for now since the pmem driver is the
only user of memremap(), but this is important to fix before more

The only affected users are SCSI multi-path via device handler

accounting. The mvsas bug manifests as a null deref oops but only on

This reverts commit 7eb418851f.
This commit is poorly justified, I can find not discusison in email,
and it clearly causes a problem.
If a device which is being recovered fails and is subsequently
re-added to an array, there could easily have been changes to the
array *before* the point where the recovery was up to. So the
recovery must start again from the beginning.
If a spare is being recovered and fails, then when it is re-added we
really should do a bitmap-based recovery up to the recovery-offset,
and then a full recovery from there. Before this reversion, we only
did the "full recovery from there" which is not corect. After this
reversion with will do a full recovery from the start, which is safer
but not ideal.
It will be left to a future patch to arrange the two different styles
of recovery.

Fixes: 7eb418851f ("md: allow a partially recovered device to be hot-added to an array.")
The size here comes from the user via the ioctl, it is a number between
1-u32max so the addition here could overflow on 32 bit systems.
