MISC_DEVICES option alone does not select any kernel code and can cause dependency build warnings, such as:
warning: (KS8851 && AX88796_93CX6 && RTL8180 && RTL8187 && ADM8211 && RT2400PCI && RT2500PCI && RT61PCI && RT2800PCI && R8187SE) selects EEPROM_93CX6 which has unmet direct dependencies (MISC_DEVICES)
As the current drivers/misc/Kconfig stands, it is only possible to select the drivers below if MISC_DEVICES option is selected:
source "drivers/misc/c2port/Kconfig"
source "drivers/misc/eeprom/Kconfig"
source "drivers/misc/cb710/Kconfig"
source "drivers/misc/iwmc3200top/Kconfig"
source "drivers/misc/ti-st/Kconfig"
source "drivers/misc/lis3lv02d/Kconfig"
source "drivers/misc/carma/Kconfig"
source "drivers/misc/altera-stapl/Kconfig"
So remove MISC_DEVICES option so that nothing is dependant on it.

When an interrupt comes in, we read the reason
bits and collect them into "trans_pcie->inta".
This happens with the spinlock held. However,
there's a bug resetting this variable -- that
happens after the spinlock has been released.
This means that it is possible for interrupts
to be missed if the reset happens after some
other interrupt reasons were already added to
the variable.
I found this by code inspection, looking for a
reason that we sometimes see random commands
time out. It seems possible that this causes
such behaviour, but I can't say for sure right
now since it happens extremely infrequently on
my test systems.

bond_alb_init_slave() is called from bond_enslave() and sets the slave's MAC
address. This is done differently for TLB and ALB modes.
bond->alb_info.rlb_enabled is used to discriminate between the two modes but
this flag may be uninitialized if the slave is being enslaved prior to calling
bond_open() -> bond_alb_initialize() on the master.
It turns out all the callers of alb_set_slave_mac_addr() pass
bond->alb_info.rlb_enabled as the hw parameter.
This patch cleans up the unnecessary parameter of alb_set_slave_mac_addr() and
makes the function decide based on the bonding mode instead, which fixes the
above problem.

If the MAC is invalid or not implemented, do not abort the probe. Issue
a warning and prevent bringing the interface up until a MAC is set manually
(via ifconfig $IFACE hw ether $MAC).
Tested on two platforms, one with a valid MAC, the other without a MAC. The real
MAC is used if present, the interface fails to come up until the MAC is set on
the other. They successfully get an IP over DHCP and pass a simple ping and
login over ssh test.
This is meant to allow the Inforce SYS940X development board:
http://www.inforcecomputing.com/SYS940X_ECX.html
(and others suffering from a missing MAC) to work with the mainline kernel.
Without this patch, the probe will fail and the interface will not be created,
preventing the user from configuring the MAC manually.
This does not make any attempt to address a missing or invalid MAC for the
pch_phub driver.

Kdump kernels leave MSI-X interrupts (as setup by the crashed kernel)
enabled. However, kdump only enables one CPU in the new environment,
thus causing tg3 to abort MSI-X setup. When the driver attempts to
enable INTA or MSI interrupt modes on a kdump kernel, interrupt
delivery fails.
This patch attempts to workaround the problem by forcing the driver
to enable a single MSI-X interrupt. In such a configuration, the
device's multivector interrupt mode must be disabled.

Documentation states that the KeyMiss flag is only valid if RxFrameOK is
unset, however empirical evidence has shown that this is false.
When KeyMiss is set (and RxFrameOK is 1), the hardware passes a valid frame
which has not been decrypted. The driver then falsely marks the frame
as decrypted, and when using CCMP this corrupts the rx CCMP PN, leading
to connection hangs.

Same devices can generate interrupt without properly setting bit in
INT_SOURCE_CSR register (spurious interrupt), what will cause IRQ line
will be disabled by interrupts controller driver.
We discovered that clearing INT_MASK_CSR stops such behaviour. We
previously first read that register, and then clear all know interrupt
sources bits and do not touch reserved bits. After this patch, we write
to all register content (I believe writing to reserved bits on that
register will not cause any problems, I tested that on my rt2800pci
device).
This fix very bad performance problem, practically making device
unusable (since worked without interrupts), reported in:
https://bugzilla.redhat.com/show_bug.cgi?id=658451
We previously tried to workaround that issue in commit
4ba7d99978 "rt2800pci: handle spurious
interrupts", but it was reverted in commit
82e5fc2a34
as thing, that will prevent to detect real spurious interrupts.

This is basically just a cleanup. Large positive numbers get counted as
negative but then get implicitly cast to positive again for the checks
that matter.
This does make a small difference in ipw_handle_promiscuous_rx() when we
test "if (unlikely((len + IPW_RX_FRAME_SIZE) > skb_tailroom(rxb->skb)))"
It should return there, but we don't return until a couple lines later
when we test "if (len > IPW_RX_BUF_SIZE - sizeof(struct ipw_rt_hdr)) {".
The difference is that in the second test the sizeof() means that there
is an implied cast to unsigned.

When TX time stamping for PTP messages is enabled on a socket, a time
stamp is returned on the socket error queue to the user space application
after the frame was transmitted. The transmitted frame is also returned on
the error queue so that an application knows to which frame the time stamp
belongs.
In the current implementation the TxFCB is immediately followed by the
frame. Since the eTSEC inserts the TX time stamp 8 bytes after the TxFCB,
parts of the frame have been overwritten and an invalid frame was returned
on the socket error queue.
This patch fixes the described problem by adding additional 16 padding
bytes between the TxFCB and the frame for all messages sent from a time
stamping enabled socket (other sockets are not affected).

When there is not enough headroom in the skb a private copy will be made.
However, the private copy had no reference to the socket and consequently
no time stamp could be queued on the socket error queue during the
skb_tstamp_tx function. This patch fixes this issue by also stealing the
sock reference from the original skb after making the private copy.

Introduce function mdiobus_alloc_size() as an alternative to mdiobus_alloc().
Most callers of mdiobus_alloc() also allocate a private data structure, and
then manually point bus->priv to this object. mdiobus_alloc_size()
combines the two operations into one, which simplifies memory management.
The original mdiobus_alloc() now just calls mdiobus_alloc_size(0).

It appears that you can only read the sprom contents with aligned 16-bit
reads: anything else causes at least some versions of the broadcom
chipset to abort the PCI transaction, returning 0xff.
This apparently doesn't trigger very often, because most setups don't
use an external srom chip, and the OTP sprom loading doesn't have this
issue. But at least the current 11" Macbook Air does trigger it, and
wireless communications were broken as a result.

The commit "ath9k: Fix invalid noisefloor reading due to channel update"
preserves the current channel noisefloor readings before updating
channel type at the same channel index. It is also updating the curchan
pointer. As survey updation is also referring curchan pointer to fetch
the appropriate index, which might leads to invalid memory access. This
patch partially reverts the change and stores the noise floor history
buffer before updating channel type w/o updating curchan.

- Tx processing is moved from the irq handler to NAPI poll
- link events and obscure event processing is moved to its proper work queue
Locking rules undergo some changes through the driver.
- the driver offers the usual lock-free Tx path
- besides the IRQ handler, the link event task schedules the napi handler.
The driver thus adds some internal locking to prevent a loop when both
must be disabled.
- the reset task keeps being scheduled from the Tx watchdog handler, thus
with implicit Tx queue disabling. It does not need to care about irq,
only napi softirq and competing task.
- it is not worth to add a dedicated lock between {g, s}et_wol and
rhine_shutdown. It should not hurt no narrow it down a bit though.
- rhine_reset_task must keep its huge spin_lock_bh protected section due
to :
- races for the CAM registers (see rhine_vlan_rx_{add, kill}_vid)
- implicit use of napi_enable (see init_registers)
- use of the same lock for stats read / update exclusion between
napi rx processing and rhine_get_stats
- rhine_resume requires a softirq disabled section for the same reason
as rhine_reset_task
- {free, request}_irq have been replaced with IntrEnable actions in
rhine_{suspend, resume}. It is hidden behind init_registers for the
latter.

Commit 4e16d6ebd6 (r6040: define more MCR0
register bits) added #define values for MCR0 register bits and converted
uses of hardcoded magic values to uses of these defines.
However, one of the conversions looks suspicious:
#define MCR0 0x00 /* Control register 0 */
+#define MCR0_RCVEN 0x0002 /* Receive enable */
+#define MCR0_XMTEN 0x1000 /* Transmission enable */
/* Init RDC private data */
- lp->mcr0 = 0x1002;
+ lp->mcr0 = MCR0_XMTEN | MCR0;
I believe what was meant here was MCR0_XMTEN | MCR0_RCVEN, which makes
sense and matches the original values.

When a bnx2x device encounters parity errors, it will not respond to all
SPQ messages. As a result, the shutdown sequence before reset can take
a long time as the ulp drivers (bnx2i/bnx2fc) have to wait for timeout
of all such messages.
To improve this scenario, when bnx2x returns error on the SPQ, we'll send
an immediate response to the ulp drivers to avoid such lengthy timeouts.
Adjust the return code of relevant functions to return error only if
the message cannot be sent on the SPQ so that we'll generate an error
completion to the ulp drivers.

is off and set it up for generating a wakeup event after the link has been
detected again. This feature is disabled by default.
Based on e1000e's runtime PM code.
Changes since v1:
Don't suspend the device when shutting down the interface.
Avoid race between runtime suspending and ethtool operations.

As reported by Steven Rostedt, e1000 has a lockdep splat added
during the recent merge window. The issue is that
cancel_delayed_work is called while holding our private mutex.
There is no reason that I can see to hold the mutex during pci
shutdown, it was more just paranoia that I put the mutex_lock
around the call to e1000_down.
In a quick survey lots of drivers handle locking differently when
being called by the pci layer. The assumption here is that we
don't need the mutexes' protection in this function because
the driver could not be unloaded while in the shutdown handler
which is only called at reboot or poweroff.

The 'name', 'owner', and 'mod_name' members are redundant with the
identically named fields in the 'driver' sub-structure. Rather than
switching each instance to specify these fields explicitly, introduce
a macro to simplify this.
Eliminate further redundancy by allowing the drvname argument to
DEFINE_XENBUS_DRIVER() to be blank (in which case the first entry from
the ID table will be used for .driver.name).
Also eliminate the questionable xenbus_register_{back,front}end()
wrappers - their sole remaining purpose was the checking of the
'owner' field, proper setting of which shouldn't be an issue anymore
when the macro gets used.
v2: Restore DRV_NAME for the driver name in xen-pciback.

When USB driver requires padding at the end of frame or URB it will report
this need by increasing return value of get_tx_data_len callback. Common
USB code uses that return value as desired URB length.
Ensure that appropriate part of skb's tailroom exists and is zeroed.

Older USB drivers does not append end padding to skb but instead report
it in size of data to be transmitted to HW. rt2800usb should follow that
behaviour. Custom write_tx_data callback which was adding pad to skb
is not be needed any more.
Thanks to this patch frames handed back from rt2800usb to mac80211 will
no longer contain end padding.

AR9003 chips read tx status from ring buffer whose max number of
status descriptor is mininal compared to max number of tx buffers.
On a stress condition, it can be easily overflown which might cause
false tx hung detection. Though increasing number of max status
descriptors consumes more memory, it helps to avoid false positive
chip resets.
