[NEUS7920-133]wlbt: allow MAC address file to be in /proc

One customer is placing the MAC address in procfs, and
the current mx140_file reader cannot handle the
zero length virtual files. Fix this and check that
a loaded file contains a valid MAC address.

This is the replacement for conflicting customer code
that appeared upstream.

[NEUS7920-133][9610] wlbt: Use single threaded wq in hip4 bh

We have recently (A50 project) observed several issues to schedule
hip4_wq work, most likely because the kernel is blocked and is not
granting us CPU cycles.

In current implementation the work is added in the systemwq. Systemwq
might be easily affected by other subsystems adding batch works that
might eventually block our pending work.

In order to avoid using systemwq, the patch creates a new singlethread
workqueue and adds the non-napi process context bottom half works in there.

FROMGIT, BACKPORT: mac80211-next: rtnetlink wifi simulation device

This device takes over an existing network device and produces a
new one that appears like a wireless connection, returning enough canned
responses to nl80211 to satisfy a standard connection manager. If
necessary, it can also be set up one step removed from an existing
network device, such as through a vlan/80211Q or macvlan connection to
not disrupt the existing network interface.

To use it to wrap a bare ethernet connection:

ip link add link eth0 name wlan0 type virt_wifi

You may have to rename or otherwise hide the eth0 from your connection
manager, as the original network link will become unusuable and only
the wireless wrapper will be functional. This can also be combined with
vlan or macvlan links on top of eth0 to share the network between
distinct links, but that requires support outside the machine for
accepting vlan-tagged packets or packets from multiple MAC addresses.

This is being used for Google's Remote Android Virtual Device project,
which runs Android devices in virtual machines. The standard network
interfaces provided inside the virtual machines are all ethernet.
However, Android is not interested in ethernet devices and would rather
connect to a wireless interface. This patch allows the virtual machine
guest to treat one of its network connections as wireless rather than
ethernet, satisfying Android's network connection requirements.

We believe this is a generally useful driver for simulating wireless
network connections in other environments where a wireless connection is
desired by some userspace process but is not available.

This is distinct from other testing efforts such as mac80211_hwsim by
being a cfg80211 device instead of mac80211 device, allowing straight
pass-through on the data plane instead of forcing packaging of ethernet
data into mac80211 frames.

[RAMEN9610-14440] UPSTREAM: kasan: support alloca() poisoning

clang's AddressSanitizer implementation adds redzones on either side of
alloca()ed buffers.  These redzones are 32-byte aligned and at least 32
bytes long.

__asan_alloca_poison() is passed the size and address of the allocated
buffer, *excluding* the redzones on either side.  The left redzone will
always be to the immediate left of this buffer; but AddressSanitizer may
need to add padding between the end of the buffer and the right redzone.
If there are any 8-byte chunks inside this padding, we should poison
those too.

__asan_allocas_unpoison() is just passed the top and bottom of the dynamic
stack area, so unpoisoning is simpler.

[RAMEN9610-14440] BACKPORT: kasan: add compiler support for clang
