455f3e76cf brcmfmac: fix P2P_DEVICE ethernet address generation
The firmware has a requirement that the P2P_DEVICE address should
be different from the address of the primary interface. When not
specified by user-space, the driver generates the MAC address for
the P2P_DEVICE interface using the MAC address of the primary
interface and setting the locally administered bit. However, the MAC
address of the primary interface may already have that bit set causing
the creation of the P2P_DEVICE interface to fail with -EBUSY. Fix this
by using a random address instead to determine the P2P_DEVICE address.

933897342d brcmfmac: add possibility to obtain firmware error
The feature module needs to evaluate the actual firmware error return
upon a control command. This adds a flag to struct brcmf_if that the
caller can set. This flag is checked to determine the error code that
needs to be returned.

6508de0305 iwlwifi: mvm: Correctly set the tid for mcast queue
In the scheduler config command, the meaning of tid == 0xf was intended
to indicate the configuration is for management frames. However,
tid == 0xf was also used for the multicast queue that was meant only
for multicast data frames, which resulted with the FW not encrypting
multicast data frames.

As multicast frames do not have a QoS header, fix this by setting
tid == 0, to indicate that this is a data queue and not management
one.

When the GTK is installed, we install it to HW with the

Mac80211 will try to remove it only after the AP sta is

This is a valid situation, but a previous commit removed
the early return and added a return with error value, which
resulted in an error message that is confusing to users.

8745f12a66 iwlwifi: avoid collecting firmware dump if not loaded
Trying to collect firmware debug data while firmware
is not loaded causes various errors (e.g. failing NIC access).
This causes even a bigger issue if at that time the
HW radio is off.
In that case, when later turning the radio on, the Driver
fails to read the HW (registers contain garbage values).
(It may be that the CSR_GP_CNTRL_REG_FLAG_RFKILL_WAKE_L1A_EN
bit is cleared on faulty NIC access - since the same behavior
was seen in HW RFKILL toggling before setting that bit.)

63dd5d022f iwlwifi: mvm: fix assert 0x2B00 on older FWs
We should add the multicast station before adding the
broadcast station.

However, in older FW, the firmware will start beaconing
when we add the multicast station, and since the broadcast
station is not added at this point so the transmission
of the beacon will fail on assert 0x2b00.

This is fixed in later firmware, so make the order

In AP mode, when a new station associates, rs is initialized immediately
upon association completion, before the phy context is updated with the
association parameters, so the sta bandwidth might be wider than the phy
context allows.
To avoid this issue, always initialize rs with 20mhz bandwidth rate, and
after authorization, when the phy context is already up-to-date, re-init
rs with the correct bw.

4437ba7ee7 iwlwifi: pcie: don't warn if we use all the transmit pointers
Our Transmit Frame Descriptor (TFD) is a DMA descriptor that
includes several pointers to be able to transmit a packet
which is not physically contiguous.

Depending on the hardware being use, we can have 20 or 25
pointers in a single TFD. In both cases, it is more than
enough and it is quite hard to hit this limit.
It has been reported that when using specific applications
(Ktorrent), we can actually use all the pointers and then
a long standing bug showed up.

When we free the TFD, we check its number of valid pointers
and make sure it doesn't exceed the number of pointers the
hardware support.
This check had an off by one bug: it is perfectly valid to
free the 20 pointers if the TFD has 20 pointers.

Fix that.

In IBSS, the mac80211 sets the cab_queue to be invalid.

API, instead of being applied for all paths.

In addition, add a missing NL80211_IFTYPE_ADHOC to the initialization

This however is bogus since we cannot assume the last frame will be

we will end up not incrementing the PN and possibly let the next
packet to have the same PN and pass through.

Change the logic instead to driver explicitly indicate for the second
sub frame and on to be allowed to have the same PN as the first
subframe. Indicate it to mac80211 as well for the fallback queue.

7ac8ff95f4 mvpp2: fix multicast address filter
IPv6 doesn't work on the MacchiatoBIN board. It is caused by broken
multicast address filter in the mvpp2 driver.

The driver loads doesn't load any multicast entries if "allmulti" is not
set. This condition should be reversed.

The condition !netdev_mc_empty(dev) is useless (because
netdev_for_each_mc_addr is nop if the list is empty).

This patch also fixes a possible overflow of the multicast list - if
mvpp2_prs_mac_da_accept fails, we set the allmulti flag and retry.

a9a08845e9 vfs: do bulk POLL* -> EPOLL* replacement
This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:

        L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
        for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
    done

with de-mangling cleanups yet to come.

NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do.  But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.

The next patch from Al will sort out the final differences, and we
should be all done.

f8d0cbf28d xtensa: fix build with KASAN
The commit 917538e212 ("kasan: clean up KASAN_SHADOW_SCALE_SHIFT
usage") removed KASAN_SHADOW_SCALE_SHIFT definition from
include/linux/kasan.h and added it to architecture-specific headers,
except for xtensa. This broke the xtensa build with KASAN enabled.
Define KASAN_SHADOW_SCALE_SHIFT in arch/xtensa/include/asm/kasan.h

5d13c73179 nios2: dts: Remove leading 0x and 0s from bindings notation
Improve the DTS files by removing all the leading "0x" and zeros to fix the
following dtc warnings:

Warning (unit_address_format): Node /XXX unit name should not have leading "0x"

and

Warning (unit_address_format): Node /XXX unit name should not have leading 0s

Converted using the following command:

find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -E -i -e "s/@0x([0-9a-fA-F\.]+)\s?\{/@\L\1 \{/g" -e "s/@0+([0-9a-fA-F\.]+)\s?\{/@\L\1 \{/g" {} +

For simplicity, two sed expressions were used to solve each warnings separately.

To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before the
the opening curly brace:

c591c2e36c powerpc/pci: Fix broken INTx configuration via OF
59f47eff03 ("powerpc/pci: Use of_irq_parse_and_map_pci() helper")
replaced of_irq_parse_pci() + irq_create_of_mapping() with
of_irq_parse_and_map_pci(), but neglected to capture the virq
returned by irq_create_of_mapping(), so virq remained zero, which
caused INTx configuration to fail.

Save the virq value returned by of_irq_parse_and_map_pci() and correct
the virq declaration to match the of_irq_parse_and_map_pci() signature.

523ca58b7d kconfig: remove const qualifier from sym_expand_string_value()
This function returns realloc'ed memory, so the returned pointer
must be passed to free() when done.  So, 'const' qualifier is odd.
It is allowed to modify the expanded string.
