Some drivers like i2c-gpio do not have dedicated pinctrl states. They
broke when error checking for pinctrl was added. Detect them now, and in
their case, simply skip over pinctrl configuration.

osdc->last_linger_id is a counter for lreq->linger_id, which is used
for watch cookies. Starting with a large integer should ease the task
of telling apart kernel and userspace clients.

If your data pool was pool 0, ceph_file_layout_from_legacy()
transform that to -1 unconditionally, which broke upgrades.
We only want do that for a fully zeroed ceph_file_layout,
so that it still maps to a file_layout_t. If any fields
are set, though, we trust the fl_pgpool to be a valid pool.

Splice read/write implementation changed recently. When using
generic_file_splice_read(), iov_iter with type == ITER_PIPE is
passed to filesystem's read_iter callback. But ceph_sync_read()
can't serve ITER_PIPE iov_iter correctly (ITER_PIPE iov_iter
expects pages from page cache).
Fixing ceph_sync_read() requires a big patch. So use default
splice read callback for now.

mlxsw: Couple of router fixes

====================
Signed-off-by: David S. Miller <davem@davemloft.net>

Since now, the table with same id in multiple netnamespaces were squashed
to a single virtual router. That is not only incorrect, it also causes
error messages when trying to use RALUE register to do double remove
of FIB entries, like this one:
mlxsw_spectrum 0000:03:00.0: EMAD reg access failed (tid=facb831c00007b20,reg_id=8013(ralue),type=write,status=7(bad parameter))
Since we don't allow ports to change namespaces (NETIF_F_NETNS_LOCAL),
and the infrastructure is not yet prepared to handle netnamespaces, just
ignore FIB notification events for non-init namespaces. That is clear to
do since we don't need to offload them.

__neigh_create function works in a different way than assumed.
It passes "n" as a parameter to ndo_neigh_construct. But this "n" might
be destroyed right away before __neigh_create() returns in case there is
already another neighbour struct in the hashtable with the same dev and
primary key. That is not expected by mlxsw_sp_router_neigh_construct()
and the stored "n" points to freed memory, eventually leading to crash.
Fix this by doing tight 1:1 coupling between neighbour struct and
internal driver neigh_entry. That allows to narrow down the key in
internal driver hashtable to do lookups by "n" only.

pm_rst, aclk_rst, pclk_rst was controlled by ROM code so the software
wasn't needed to control it again in theory. But it didn't work properly,
so we do need to do it again and add enough delay between the assert of
pm_rst and the deassert of pm_rst. The Soc intergrated with this
controller, rk3399, is still under MP test internally, so the backward
compatibility won't be a big deal.

When a LOCALINV WR is flushed, the frmr is marked STALE, then
frwr_op_unmap_sync DMA-unmaps the frmr's SGL. These STALE frmrs
are then recovered when frwr_op_map hunts for an INVALID frmr to
use.
All other cases that need frmr recovery leave that SGL DMA-mapped.
The FRMR recovery path unconditionally DMA-unmaps the frmr's SGL.
To avoid DMA unmapping the SGL twice for flushed LOCAL_INV WRs,
alter the recovery logic (rather than the hot frwr_op_unmap_sync
path) to distinguish among these cases. This solution also takes
care of the case where multiple LOCAL_INV WRs are issued for the
same rpcrdma_req, some complete successfully, but some are flushed.

The TIOCMIWAIT implementation would return -EINVAL if any of the three
supported signals were included in the mask.
Instead of returning an error in case TIOCM_CTS is included, simply
drop the mask check completely, which is in accordance with how other
drivers implement this ioctl.

At the moment we allocate enough sg table entries assuming we
will not be able to do any coalescing. But since in practice
we most often can, and more so very effectively, this ends up
wasting a lot of memory.
A simple and effective way of trimming the over-allocated
entries is to copy the table over to a new one allocated to the
exact size.
Experiments on my freshly logged and idle desktop (KDE) showed
that by doing this we can save approximately 1 MiB of RAM, or
when running a typical benchmark like gl_manhattan I have
even seen a 6 MiB saving.
More complicated techniques such as only copying the last used
page and freeing the rest are left to the reader.
v2:
* Update commit message.
* Use temporary sg_table on stack. (Chris Wilson)
v3:
* Commit message update.
* Comment added.
* Replace memcpy with copy assignment.
