Since 0 is a valid DMA address, we cannot use the physical address to
check whether a TX descriptor is valid and is holding a DMA mapping.
Use the "cntrl" member of the descriptor to make this decision, as it
contains at least the length of the buffer, so 0 points to an
uninitialised buffer.

When axienet_dma_bd_init() bails out during the initialisation process,
it might do so with parts of the structure already allocated and
initialised, while other parts have not been touched yet. Before
returning in this case, we call axienet_dma_bd_release(), which does not
take care of this corner case.
This is most obvious by the first loop happily dereferencing
lp->rx_bd_v, which we actually check to be non NULL *afterwards*.
Make sure we only unmap or free already allocated structures, by:
- directly returning with -ENOMEM if nothing has been allocated at all
- checking for lp->rx_bd_v to be non-NULL *before* using it
- only unmapping allocated DMA RX regions
This avoids NULL pointer dereferences when initialisation fails.

When we fail allocating the DMA buffers in axienet_dma_bd_init(), we
report this error, but carry on with initialisation nevertheless.
This leads to a kernel panic when the driver later wants to send a
packet, as it uses uninitialised data structures.
Make the axienet_device_reset() routine return an error value, as it
contains the DMA buffer initialisation. Make sure we propagate the error
up the chain and eventually fail the driver initialisation, to avoid
relying on non-initialised buffers.

The DMA error handler routine is currently a tasklet, scheduled to run
after the DMA error IRQ was handled.
However it needs to take the MDIO mutex, which is not allowed to do in a
tasklet. A kernel (with debug options) complains consequently:

Similar to axienet, the temac driver is now architecture agnostic, and
can be at least compiled for several architectures.
Especially the fact that this is a soft IP for implementing in FPGAs
makes the current restriction rather pointless, as it could literally
appear on any architecture, as long as an FPGA is connected to the bus.
The driver hasn't been actually tried on any hardware, it is just a
drive-by patch when doing the same for axienet (a similar patch for
axienet is already merged).
This (temac and axienet) have been compile-tested for:
alpha hppa64 microblaze mips64 powerpc powerpc64 riscv64 s390 sparc64
(using kernel.org cross compilers).

Kalle Valo says:
====================
wireless-drivers-next patches for v5.7
Second set of patches for v5.7. Lots of cleanup patches this time, but
of course various new features as well fixes.
When merging with wireless-drivers this pull request has a conflict in:
drivers/net/wireless/intel/iwlwifi/pcie/drv.c
To solve that just drop the changes from commit cf52c8a776d1 in
wireless-drivers and take the hunk from wireless-drivers-next as is.
The list of specific subsystem device IDs are not necessary after
commit d6f2134a3831 (in wireless-drivers-next) anymore, the detection
is based on other characteristics of the devices.
Major changes:
qtnfmac
* support WPA3 SAE and OWE in AP mode
ath10k
* support for getting btcoex settings from Device Tree
* support QCA9377 SDIO device
ath11k
* add HE rate accounting
* add thermal sensor and cooling devices
mt76
* MT7663 support for the MT7615 driver

The following modify sequence (loosely based on ipoib) will lose a pkey
modifcation:
- Modify (pkey index, port)
- Modify (new pkey index, NO port)
After the first modify, the qp_pps list will have saved the pkey and the
unit on the main list.
During the second modify, get_new_pps() will fetch the port from qp_pps
and read the new pkey index from qp_attr->pkey_index. The state will
still be zero, or IB_PORT_PKEY_NOT_VALID. Because of the invalid state,
the new values will never replace the one in the qp pps list, losing the
new pkey.
This happens because the following if statements will never correct the
state because the first term will be false. If the code had been executed,
it would incorrectly overwrite valid values.
if ((qp_attr_mask & IB_QP_PKEY_INDEX) && (qp_attr_mask & IB_QP_PORT))
new_pps->main.state = IB_PORT_PKEY_VALID;
if (!(qp_attr_mask & (IB_QP_PKEY_INDEX | IB_QP_PORT)) && qp_pps) {
new_pps->main.port_num = qp_pps->main.port_num;
new_pps->main.pkey_index = qp_pps->main.pkey_index;
if (qp_pps->main.state != IB_PORT_PKEY_NOT_VALID)
new_pps->main.state = IB_PORT_PKEY_VALID;
}
Fix by joining the two if statements with an or test to see if qp_pps is
non-NULL and in the correct state.

For non-fatal syndromes like LOCAL_LENGTH_ERR, recovery shouldn't be

This misleads the recovery flow which assumes that the RQ is really in

In striding RQ mode, the buffers of an RX WQE are first
prepared and posted to the HW using a UMR WQEs via the ICOSQ.
We maintain the state of these in-progress WQEs in the RQ
SW struct.
In the flow of ICOSQ recovery, the corresponding RQ is not
in error state, hence:
- The buffers of the in-progress WQEs must be released
and the RQ metadata should reflect it.
- Existing RX WQEs in the RQ should not be affected.
For this, wrap the dealloc of the in-progress WQEs in
a function, and use it in the ICOSQ recovery flow
instead of mlx5e_free_rx_descs().

The new macro set has a consistent namespace and uses C99 initializers
instead of the grufty C89 ones.
Get rid the of most local macro wrappers for consistency. The ones which
make sense for readability are renamed to X86_MATCH*.
In the centrino driver this also removes the two extra duplicates of family
6 model 13 which have no value at all.

get_mode() is used to retrieve the active mode state. Settings-A
config is used during active state, whilst Settings-B is for
suspend. This means we only need to check the sleep field of each
buck and LDO as that field solely relates to Settings-A config.
This change is a clone of the get_mode() update which was committed
as part of:

Commit 54ff4a1d1732 ("MIPS: Alchemy: pata_platform for DB1200")
from year 2014 converted the only user of au1xxx-ide IDE host
driver (MIPS Alchemy DB1200 platform) to use pata_platform
libata host driver instead. This patch removes dead au1xxx-ide
driver code.

struct partition is the on-disk format of a MSDOS partition table entry.
Move it out of genhd.h into a new msdos_partition.h header and give it
a msdos_ prefix to avoid confusion.
Also move the magic number from block/partitions/msdos.h to the new
header so that it can be used by the SCSI drivers looking at the DOS
partition tables.

There is no good reason for __bdevname to exist. Just open code
printing the string in the callers. For three of them the format
string can be trivially merged into existing printk statements,
and in init/do_mounts.c we can at least do the scnprintf once at
the start of the function, and unconditional of CONFIG_BLOCK to
make the output for tiny configfs a little more helpful.
