- An NVMe pull request from Christoph, with a few select fixes.
One of them fix a polling regression in this series, in which it's
trivial to cause the kernel to disable most of the hardware queue
interrupts.
- Fixup for a blk-mq queue usage imbalance on request allocation,
from Keith.
- A xen block pull request from Konrad, fixing two issues with
xen/xen-blkfront"

Pull rdma fixes from Doug Ledford:
"Fourth set of -rc fixes for 4.13 cycle. This is all of the -rc fixes
that we know of. I suspect this will be the last rc pull request, but
you never know, I could be wrong.
Nothing major here. There are the i40iw patches I mentioned in my last
pull request minus one that I pulled out because it wasn't a fix and
not appropriate for the rc cycle. Then a few other items trickled in
and were added to the pull request. It's fairly small aside from those
five i40iw patches
- Set of five i40iw fixes (the first of these is rather large by line
count consideration, but I decided to send it because if fixes a
legitimate issue and the line count is because it does so by
creating a new function and using it where needed instead of just
patching up a few lines...a smaller fix could probably be done, but
the larger fix is the better code solution)
- One vmw_pvrdma fix
- One hns_roce fix (this silences a checker warning, but can't
actually happen, I expect a patch to remove this from all drivers
that share this same check in for-next)
- One iw_cxgb4 fix

Enables multiple Interrupt vectors. Driver is requesting the max
MSIX vectors based on the number of online cpus and creates upto
9 MSIx vectors (1 for control path and 8 for data path).

list.
4.13 regression fix:
- imx7d-sdb pinctrl support regressed in 4.13 due to an incomplete
patch
DT fixes for recently added devices:
- badly copied DT entries on imx6qdl-nitrogen6_som broke PCI reset
- sama5d2 memory controller had the wrong ID and registers
- imx7 power domains did not work correctly with deferred probing
(driver added in 4.12)
- Allwinner H5 pinctrl (added in 4.12) did not work right with GPIO
interrupts
Fixes for older bugs that just got noticed:
- i.MX25 ADC support (added in 4.6) apparently never worked right due
to a missing 'ranges' property in DT.
- Renesas Salvador Audio support (added in v4.5) was broken for
device repeated bind/unbind due to a naming conflict.
- Various allwinner boards are missing an 'ethernet' alias in DT,
leading to unstable device naming.

replace it with a struct assignment.

Some drivers (specifically the nes IB driver), want to create a lot of
sysfs driver attributes. Instead of open-coding the creation and
removal of these files (and getting it wrong btw), it's a better idea to
let the driver core handle all of this logic for us.
So add a new field to the pci driver structure, **groups, that allows
pci drivers to specify an attribute group list it wishes to have created
when it is registered with the driver core.
Big bonus is now the driver doesn't race with userspace when the sysfs
files are created vs. when the kobject is announced, so any script/tool
that actually wanted to use these files will not have to poll waiting
for them to show up.

====================
s390/net: more updates for 4.14
please apply another batch of qeth patches for net-next.
This reworks the xmit path for L2 OSAs to use skb_cow_head() instead of
skb_realloc_headroom().
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
|

Taking a full copy via skb_realloc_headroom() on every xmit is overkill
and wastes CPU time; all we actually need is to push on the qeth_hdr.
So rework the L2 OSA TX path to avoid the copy.
Minor complications arise because struct qeth_hdr must not cross a page
boundary. So add a new helper qeth_push_hdr() that catches this, and
falls back to the hdr cache that we already use for IQDs.
This change uncovered that qeth's TX completion takes rather long.
Now that we no longer free the original skb straight away and thus call
skb->destructor later than before, throughput regresses significantly.
For now, restore old behaviour by adding an explicit skb_orphan(),
and a big TODO to improve the TX completion time.

For TSO we need to skip the skb's qeth/IP/TCP headers when mapping

The TSO code already calculates the length of its header element,

For IQD we already need to fix up the qeth_hdr's length field, and
future changes will require more flexibility for OSA as well. The
device-specific path knows best what header length it requires, so just
pass it from there.
While at it, remove the unused qeth_card parameter.
No functional change.

l2_hard_start_xmit() actually doesn't contain much shared code,
and having device-specific paths makes isolated changes a lot easier.
So split it into three routines for IQD, OSN and OSD/OSM/OSX.

The dereference before check is wrong and leads to an oops when
p_filter_chain is NULL. The check needs to be done on the pointer to
prevent NULL dereference.

"map" is a valid pointer. We wanted to return "err" instead. Also
let's return a zero literal at the end.

====================
liquidio: initialization fixes for embedded firmware
Fix problems when using an adapter w/embedded f/w (param "fw_type=none").
1. Add support for PF FLR when exiting.
2. Skip some initialization (don't try to load f/w, activate consoles).
3. Issue credits BEFORE enabling DROQs.
