All of the rtlwifi family of drivers have a similar routine that acquires
the hardware info from efuse and initializes a number of variables in the
driver's private area. A common routine is created for all drivers to use.

As interrupt is read in interrupt handler as well as interrupt processing
thread, we observed a corner case issue for MSI in which interrupt gets
processed twice.
This patch moves interrupt reading code for MSI mode from
mwifiex_interrupt_status() to mwifiex_pcie_process_int() to avoid the
issue.

The PCIe driver didn't mask the host interrupts before trying to tear
down. This causes lockups at reboot or rmmod when using MSI-X on 8997,
since the MSI handler gets confused and locks up the system.
Also tested on 8897, which does not support MSI-X (and wasn't
experiencing this same bug). No regressions seen there.

The two members min_scan_time and max_scan_time of structure
"mwifiex_ie_types_btcoex_scan_time" are of two bytes each. The values
are assigned directtly from firmware without endian conversion handling.
So, wrong datas will get saved in big-endian systems.
This patch converts the values into cpu's byte order before assigning them
into the local members.

New firmwares (e.g. 10.10.69.36 for BCM4366) support "interface_remove"
for removing interfaces. Try to use this method on cfg80211 request. In
case of older firmwares (e.g. 7.35.177.56 for BCM43602 as I tested) this
will just result in firmware rejecting command and this won't change any
behavior.

So far when receiving event about in-firmware-interface removal our
event worker was notifying listener and afterwards it was removing Linux
interface.
First of all it was resulting in slightly unexpected order. The listener
(del_virtual_intf callback) was (usually) returning with success before
we even called unregister_netdev(ice).
Please note this couldn't be simply fixed by changing order of calls in
brcmf_fweh_handle_if_event as unregistering interface earlier could free
struct brcmf_if.
Another problem of current implementation are possible lockups. Focus on
the time slot between calling event handler and removing Linux
interface. During that time original caller may leave (unlocking rtnl
semaphore) *and* another call to the same code may be done (locking it
again). If that happens our event handler will stuck at removing Linux
interface, it won't handle another event and will block process holding
rtnl lock.
This can be simply solved by unregistering interface in a proper
callback, right after receiving confirmation event from firmware. This
only required modifying worker to don't unregister on its own if there
is someone waiting for the event.

scan_block flag is used to block scan operation when 4 way handshake
is in progress. Sometimes it doesn't get cleared due to incomplete
association. An example is assoc request/response is done, but add key
operation get canceled in some corner cases. As a result, further
association/scan operations are blocked.
This patch fixes the problem by clearing scan_block flag.

arch/arm64/kernel/{vdso,signal}.c include generated/vdso-offsets.h, and
therefore the symbol offsets must be generated before these files are
compiled.
The current rules in arm64/kernel/Makefile do not actually enforce
this, because even though $(obj)/vdso is listed as a prerequisite for
vdso-offsets.h, this does not result in the intended effect of
building the vdso subdirectory (before all the other objects). As a
consequence, depending on the order in which the rules are followed,
vdso-offsets.h is updated or not before arm64/kernel/{vdso,signal}.o
are built. The current rules also impose an unnecessary dependency on
vdso-offsets.h for all arm64/kernel/*.o, resulting in unnecessary
rebuilds.
This patch removes the arch/arm64/kernel/vdso/vdso-offsets.h file
generation, leaving only the include/generated/vdso-offsets.h one. It
adds a forced dependency check of the vdso-offsets.h file in
arch/arm64/kernel/Makefile which, if not up to date according to the
arch/arm64/kernel/vdso/Makefile rules (depending on vdso.so.dbg), will
trigger the vdso/ subdirectory build and vdso-offsets.h re-generation.
Automatic kbuild dependency rules between kernel/{vdso,signal}.c rules
and vdso-offsets.h will guarantee that the vDSO object is built first,
followed by the generated symbol offsets header file.

Re-organize the GUID table so that every GUID takes a single line.
This makes each line super long, but if you have a large enough terminal
(or zoom out of a small terminal) then you can see the structure at

multi-line layout.

The kernel-include directive is needed to include the auto generated rst
content from a build (pre-) process. E.g. the linux_tv Makefile
generates intermediate reST-files from header files. Since there is a O=
option:
make O=dir [targets] Locate all output files in "dir"
We need to include intermediate reST files from arbitrary (O=/tmp/foo)
locations:
The 'kernel-include' reST-directive is a replacement for the 'include'
directive. The 'kernel-include' directive expand environment variables
in the path name and allows to include files from arbitrary locations.
.. hint::
Including files from arbitrary locations (e.g. from '/etc') is a
security risk for builders. This is why the 'include' directive from
docutils *prohibit* pathnames pointing to locations *above* the
filesystem tree where the reST document with the include directive is
placed.
Substrings of the form $name or ${name} are replaced by the value of
environment variable name. Malformed variable names and references to
non-existing variables are left unchanged.

Add possibility for 32-bit user-space applications to move
the vDSO mapping.
Previously, when a user-space app called mremap() for the vDSO
address, in the syscall return path it would land on the previous
address of the vDSOpage, resulting in segmentation violation.
Now it lands fine and returns to userspace with a remapped vDSO.
This will also fix the context.vdso pointer for 64-bit, which does
not affect the user of vDSO after mremap() currently, but this
may change in the future.
As suggested by Andy, return -EINVAL for mremap() that would
split the vDSO image: that operation cannot possibly result in
a working system so reject it.
Renamed and moved the text_mapping structure declaration inside
map_vdso(), as it used only there and now it complements the
vvar_mapping variable.
There is still a problem for remapping the vDSO in glibc
applications: the linker relocates addresses for syscalls
on the vDSO page, so you need to relink with the new
addresses.
Without that the next syscall through glibc may fail:
Program received signal SIGSEGV, Segmentation fault.
