Add check of coalescing parameters received through ethtool are within
range of values supported by the HW.
Driver gets the coalescing rx/tx-usecs and rx/tx-frames as set by the
users through ethtool. The ethtool support up to 32 bit value for each.
However, mlx4 modify cq limits the coalescing time parameter and
coalescing frames parameters to 16 bits.
Return out of range error if user tries to set these parameters to
higher values.
Change type of sample-interval and adaptive_rx_coal parameters in mlx4
driver to u32 as the ethtool holds them as u32 and these parameters are
not limited due to mlx4 HW.

When sending packets as fast as possible using "cangen -g 0 -i -x", the
HI-3110 occasionally latches the interrupt pin high on completion of a
packet, but doesn't set the TXCPLT bit in the INTF register. The INTF
register contains 0x00 as if no interrupt has occurred. Even waiting
for a few milliseconds after the interrupt doesn't help.
Work around this apparent erratum by instead checking the TXMTY bit in
the STATF register ("TX FIFO empty"). We know that we've queued up a
packet for transmission if priv->tx_len is nonzero. If the TX FIFO is
empty, transmission of that packet must have completed.
Note that this is congruent with our handling of received packets, which
likewise gleans from the STATF register whether a packet is waiting in
the RX FIFO, instead of looking at the INTF register.

hi3110_get_berr_counter() may run concurrently to the rest of the driver
but neglects to acquire the lock protecting access to the SPI device.
As a result, it and the rest of the driver may clobber each other's tx
and rx buffers.
We became aware of this issue because transmission of packets with
"cangen -g 0 -i -x" frequently hung. It turns out that agetty executes
->do_get_berr_counter every few seconds via the following call stack:
CPU: 2 PID: 1605 Comm: agetty
[<7f3f7500>] (hi3110_get_berr_counter [hi311x])
[<7f130204>] (can_fill_info [can_dev])

[<80661ec0>] (SyS_recvmsg)
[<80108b20>] (ret_fast_syscall+0x0/0x1c)
agetty listens to netlink messages in order to update the login prompt
when IP addresses change (if /etc/issue contains \4 or \6 escape codes):
https://git.kernel.org/pub/scm/utils/util-linux/util-linux.git/commit/?id=e36deb6424e8
It's a useful feature, though it seems questionable that it causes CAN
bit error statistics to be queried.
Be that as it may, if hi3110_get_berr_counter() is invoked while a frame
is sent by hi3110_hw_tx(), bogus SPI transfers like the following may
occur:
=> 12 00 (hi3110_get_berr_counter() wanted to transmit
EC 00 to query the transmit error counter,
but the first byte was overwritten by
hi3110_hw_tx_frame())
=> EA 00 3E 80 01 FB (hi3110_hw_tx_frame() wanted to transmit a
frame, but the first byte was overwritten by
hi3110_get_berr_counter() because it wanted
to query the receive error counter)
This sequence hangs the transmission because the driver believes it has
sent a frame and waits for the interrupt signaling completion, but in
reality the chip has never sent away the frame since the commands it
received were malformed.
Fix by acquiring the SPI lock in hi3110_get_berr_counter().
I've scrutinized the entire driver for further unlocked SPI accesses but
found no others.

Commit 0847684cfc (PCI / PM: Simplify device wakeup settings code)
went too far and dropped the device_may_wakeup() check from
pci_enable_wake() which causes wakeup to be enabled during system
suspend, hibernation or shutdown for some PCI devices that are not
allowed by user space to wake up the system from sleep (or power off).
As a result of this, excessive power is drawn by some of the affected
systems while in sleep states or off.
Restore the device_may_wakeup() check in pci_enable_wake(), but make
sure that the PCI bus type's runtime suspend callback will not call
device_may_wakeup() which is about system wakeup from sleep and not
about device wakeup from runtime suspend.

Set __GFP_KSWAPD_RECLAIM as well, in order for huge pages to be freed

Allocating up to 32 physically contiguous pages can easily fail (and has
failed for me), and isn't necessary anyway.

As per listxattr(2):
On success, a nonnegative number is returned indicating the size
of the extended attribute name list. On failure, -1 is returned
and errno is set appropriately.
In SMB1, when the server returns an empty EA list through a listxattr(),
it will correctly return 0 as there are no EAs for the given file.
However, in SMB2+, it returns -ENODATA in listxattr() which is wrong since
the request and response were sent successfully, although there's no actual
EA for the given file.
This patch fixes listxattr() for SMB2+ by returning 0 in cifs_listxattr()
when the server returns an empty list of EAs.

The data buffer allocated on the stack can't be DMA'ed, ib_dma_map_page will
return an invalid DMA address for a buffer on stack. Even worse, this
incorrect address can't be detected by ib_dma_mapping_error. Sending data
from this address to hardware will not fail, but the remote peer will get
junk data.
Fix this by allocating the request on the heap in smb3_validate_negotiate.
Changes in v2:
Removed duplicated code on freeing buffers on function exit.
(Thanks to Parav Pandit <parav@mellanox.com>)
Fixed typo in the patch title.
Changes in v3:
Added "Fixes" to the patch.
Changed several sizeof() to use *pointer in place of struct.
Changes in v4:
Added detailed comments on the failure through RDMA.
Allocate request buffer using GPF_NOFS.
Fixed possible memory leak.
Changes in v5:
Removed variable ret for checking return value.
Changed to use pneg_inbuf->Dialects[0] to calculate unused space in pneg_inbuf.
