Pull rdma fixes from Jason Gunthorpe:
"This fixes one major regression with NFS and mlx4 due to the max_sg
rework in this merge window, tidies a few minor error_path
regressions, and various small fixes.
The HFI1 driver is broken this cycle due to a regression caused by a
PCI change, it is looking like Bjorn will merge a fix for this. Also,
the lingering ipoib issue I mentioned earlier still remains unfixed.
Summary:
- Fix possible FD type confusion crash
- Fix a user trigger-able crash in cxgb4
- Fix bad handling of IOMMU resources causing user controlled leaking
in bnxt
- Add missing locking in ipoib to fix a rare 'stuck tx' situation
- Add missing locking in cma

In calculating the global maximum number of the Scatter/Gather elements
supported, the following four maximum parameters must be taken into
consideration: max_sg_rq, max_sg_sq, max_desc_sz_rq and max_desc_sz_sq.
However instead of bringing this complexity to query_device, which still
won't be sufficient anyway (the calculations are dependent on QP type),
the safer approach will be to restore old code, which will give us 32
SGEs.

When AF_IB addresses are used during rdma_resolve_addr() a lock is not
held. A cma device can get removed while list traversal is in progress
which may lead to crash. ie

rdma_resolve_addr()
cma_resolve_ib_dev()
list_for_each() cma_remove_one()
cur_dev->device mutex_lock(&lock)
list_del();
mutex_unlock(&lock);
cma_process_remove();
Therefore, hold a lock while traversing the list which avoids such

Disable interrupts while configuring the transfer and enable them back.
We have below as the programming sequence
1. start and slave address
2. byte count and stop
In some customer platform there was a lot of interrupts between 1 and 2
and after slave address (around 7 clock cyles) if 2 is not executed
then the transaction is nacked.
To fix this case make the 2 writes atomic.

Commit fe8e93504ce8 ("irqchip/gic-v3-its: Use full range of LPIs"), removes
the cap for lpi_id_bits, which causes the following warning to trigger on a
QDF2400 server:
WARNING: CPU: 0 PID: 0 at mm/page_alloc.c:4066 __alloc_pages_nodemask

In its_alloc_lpi_tables(), lpi_id_bits is 24 in QDF2400. The allocation in

Firmware can provide zero as values for sustained performance level and
corresponding sustained frequency in kHz in order to hide the actual

Raydium touchscreen triggers interrupt storm after system-wide suspend:
[ 179.085033] i2c_hid i2c-CUST0000:00: i2c_hid_get_input: incomplete report (58/65535)
According to Raydium, Windows driver does not reset the device after system
resume.
The HID over I2C spec does specify a reset should be used at intialization, but
it doesn't specify if reset is required for system suspend.
Tested this patch on other i2c-hid touchpanels I have and those touchpanels do
work after S3 without doing reset. If any regression happens to other
touchpanel vendors, we can use quirk for Raydium devices.
There's still one device uses I2C_HID_QUIRK_RESEND_REPORT_DESCR so keep it
there.

Commit 12864ff8545f (ACPI / LPSS: Avoid PM quirks on suspend and resume
from hibernation) bypasses lpss quirks for S3 and S4, by setting a flag
for S3/S4 in acpi_lpss_suspend(), and check that flag in
acpi_lpss_resume().
But this overlooks the boot case where acpi_lpss_resume() may get called
without a corresponding acpi_lpss_suspend() having been called.
Thus force setting the flag during boot.

Calling dmi_check_system() early only works on X86. Other
architectures initialize the DMI subsystem later so it's not
ready yet when ACPI itself gets initialized.
In the best case it results in a useless call to a function which
will do nothing. But depending on the dmi implementation, it could
also result in warnings. Best is to not call the function when it
can't work and isn't needed.
Additionally, if anyone ever needs to add non-x86 quirks, it would
surprisingly not work, so document the limitation to avoid confusion.

Inside of start_xmit() the call to check if the connection is up and the
queueing of the packets for later transmission is not atomic which leaves
a window where cm_rep_handler can run, set the connection up, dequeue
pending packets and leave the subsequently queued packets by start_xmit()
sitting on neigh->queue until they're dropped when the connection is torn
down. This only applies to connected mode. These dropped packets can
really upset TCP, for example, and cause multi-minute delays in
transmission for open connections.
Here's the code in start_xmit where we check to see if the connection is
up:
if (ipoib_cm_get(neigh)) {
if (ipoib_cm_up(neigh)) {
ipoib_cm_send(dev, skb, ipoib_cm_get(neigh));
goto unref;
}
}
The race occurs if cm_rep_handler execution occurs after the above
connection check (specifically if it gets to the point where it acquires
priv->lock to dequeue pending skb's) but before the below code snippet in
start_xmit where packets are queued.
if (skb_queue_len(&neigh->queue) < IPOIB_MAX_PATH_REC_QUEUE) {
push_pseudo_header(skb, phdr->hwaddr);
spin_lock_irqsave(&priv->lock, flags);
__skb_queue_tail(&neigh->queue, skb);
spin_unlock_irqrestore(&priv->lock, flags);
} else {
++dev->stats.tx_dropped;
dev_kfree_skb_any(skb);
}
The patch acquires the netif tx lock in cm_rep_handler for the section
where it sets the connection up and dequeues and retransmits deferred
skb's.

Within show_valid_zones() the function test_pages_in_a_zone() should be
called for online memory blocks only.
Otherwise it might lead to the VM_BUG_ON due to uninitialized struct
pages (when CONFIG_DEBUG_VM_PGFLAGS kernel option is set):
page dumped because: VM_BUG_ON_PAGE(PagePoisoned(p))
------------[ cut here ]------------

That VM_BUG_ON was triggered by the page poisoning introduced in
mm/sparse.c with the git commit d0dc12e86b31 ("mm/memory_hotplug:
optimize memory hotplug").
With the same commit the new 'nid' field has been added to the struct
memory_block in order to store and later on derive the node id for
offline pages (instead of accessing struct page which might be
uninitialized). But one reference to nid in show_valid_zones() function
has been overlooked. Fixed with current commit. Also, nr_pages will
not be used any more after test_pages_in_a_zone() call, do not update
it.

The object lock was supposed to always be released during destroy, but
when the destruction retry series was integrated with the destroy series
it created a failure path that missed the unlock.

The current code grabs the private_data of whatever file descriptor
userspace has supplied and implicitly casts it to a `struct ucma_file *`,
potentially causing a type confusion.
This is probably fine in practice because the pointer is only used for
comparisons, it is never actually dereferenced; and even in the
comparisons, it is unlikely that a file from another filesystem would have
a ->private_data pointer that happens to also be valid in this context.
But ->private_data is not always guaranteed to be a valid pointer to an
object owned by the file's filesystem; for example, some filesystems just
cram numbers in there.
Check the type of the supplied file descriptor to be safe, analogous to how
other places in the kernel do it.

commit f07b3c1da92d ("HID: generic: create one input report per
application type") was effectively the same as MULTI_INPUT:
hidinput->report was never set, so hidinput_match_application()
always returned null.
Fix that by testing against the real application.
Note that this breaks some old eGalax touchscreens that expect MULTI_INPUT
instead of HID_QUIRK_INPUT_PER_APP. Enable this quirk for backward
compatibility on all non-Win8 touchscreens.

When implementing commit 7f81c8db5489 ("HID: multitouch: simplify
the settings of the various features"), I wrongly removed a test
that made sure we never try to set the second InputMode feature
to something else than 0.
This broke badly some recent Elan panels that now forget to send the
click button in some area of the touchpad.

Correct the formula for calculating the RQ page remainder,
which should be in byte granularity. The result will be
non-zero only for RQs smaller than PAGE_SIZE, as an RQ size
is a power of 2.
Divide this by the SQ stride (MLX5_SEND_WQE_BB) to get the
SQ offset in strides granularity.

Currently, the driver adjusts the bp->hw_resc.max_cp_rings by the number
of MSIX vectors used by RDMA. There is one code path in open that needs
to check the true max_cp_rings including any used by RDMA. This code
is now checking for the reduced max_cp_rings which will fail when the
number of cp rings is very small.
To fix this in a clean way, we don't adjust max_cp_rings anymore.
Instead, we add a helper bnxt_get_max_func_cp_rings_for_en() to get the
reduced max_cp_rings when appropriate.

When the driver detects that resources have changed during open, it
should reset the rx and tx rings to 0. This will properly setup the
init sequence to initialize the default rings again. We also need
to signal the RDMA driver to stop and clear its interrupts. We then
call the RoCE driver to restart if a new set of default rings is
successfully reserved.
