Generally broadcast mac address deauth is followed by stop_ap or start_ap.
In both cases, FW already has provision to send deauth; so there is no
need to handle broadcast mac deauthentication.

Station node entries should be guarded for whole of their reference
instead of just while getting node entry from station list.
It may happen that station node is retrieved may be deleted by

A crash was observed while cfg80211 del_station handler is
called while stopping AP. This was happening because we were
deleting station list and Rx reorder table entries in del_sta
handler. While station entry is being deleted here, it may happen
that station deauth event from FW would also try to delete station
entry.
This patch fixes this crash by not deleting station entries in del_station
handler. Entry would be deleted while processing station deauth event; which
is triggered by del_station command to FW.

This will enable use of physical arch timers on rk3288, where each
core comes out of reset with a different virtual offset. Using
physical timers will help with SMP booting on coreboot and older
u-boot and should also allow suspend-resume and cpu-hotplug to work on
all firmwares.
Firmware which does initialize the cpu registers properly at boot and
cpu-hotplug can remove this property from the device tree.

(kthread+0xa0/0xac) from [<c0105ef8>] (ret_from_fork+0x14/0x3c)
The reason is that f2fs calls radix_tree_insert under enabled preemption.
So, before calling it, we need to call radix_tree_preload.
Otherwise, we should use _GFP_WAIT for the radix tree, and use mutex or
semaphore to cover the radix tree operations.

This patch resolves couple of issues in ixgbevf_probe/remove():
1. Fix a case where adapter->state is tested after free_netdev() this is
same as the patch for ixgbe from Daniel Borkmann <dborkman@redhat.com>:
commit b5b2ffc0574e1f27 ("ixgbe: fix use after free adapter->state test in ixgbe_remove/ixgbe_probe")
2. Move pci_set_drvdata() after all the error checks in ixgbevf_probe() and
then add a check in ixgbevf_probe() to avoid running the cleanup functions
twice in cases where probe failed.

The driver has logic to free up used data in case any of the checks in
ixgbe_probe() fail, however there is a similar set of cleanups that can
occur on driver unload in ixgbe_remove() which can cause the rmmod command
to crash.
This patch aims to fix the logic by moving pci_set_drvdata() after all error
checks and then adds a check in ixgbe_remove() to skip it altogether if
adapter comes up empty.

returns a u16 and cannot return an error code. Unfortunately
a variety of errors can happen that completely prevent the

positive checksum value when there is no error.

The X550 hardware will use more bits in the mask, so change
the prototypes to match. This larger mask will require changes
in callers which use the higher bits. Likewise since X550 will
use different semaphore mask values and will use the lan_id

Accessing the CIAA/D register can block access to the PCI config space.
This patch removes the read/write operations to the CIAA/D registers
and makes use of standard kernel functions for accessing the PCI config
space.
In addition it moves ixgbevf_check_for_bad_vf() into the watchdog subtask
which reduces the frequency of the checks.

This change cleans up the tail writes for the ixgbe descriptor queues. The
current implementation had me confused as I wasn't sure if it was still
making use of the surprise remove logic or not.
It also adds the mmiowb which is needed on ia64, mips, and a couple other
architectures in order to synchronize the MMIO writes with the Tx queue
_xmit_lock spinlock.

This patch cleans up the page reuse code getting it into a state where all
the workarounds needed are in place as well as cleaning up a few minor
oversights such as using __free_pages instead of put_page to drop a locally
allocated page.
It also cleans up how we clear the descriptor status bits. Previously they
were zeroed as a part of clearing the hdr_addr. However the hdr_addr is a
64 bit field and 64 bit writes can be a bit more expensive on on 32 bit
systems. Since we are no longer using the header split feature the upper
32 bits of the address no longer need to be cleared. As a result we can
just clear the status bits and leave the length and VLAN fields as-is which
should provide more information in debugging.

The last time this documentation was accurate was
just over 8 years ago. In this time we've added
support for two new generations of Xbox console
controllers and dozens of third-party controllers.
This patch unifies terminology and makes it explicit
which model of controller a sentence refers to.
It also expands certain sections to address the latest
versions of Xbox controllers.
Thus this documentation should now be useful to
end users and not contain out-right untruths.
This is the patch's second revision. Prior versions
of this patch altered the driver's TODO list. That
change has been pulled out of this documentation

information by calling cpufreq_get(0). However if cpu frequency driver
is not enabled (e.g. due to unsupported DRAM chip/board on sa1110)
cpufreq_get(0) returns 0, causing incorrect timings to be programmed.
