Use the standard WARN_ON instead.
If a small kernel is desired, WARN_ON can be disabled globally.Also remove SSB_DEBUG. Besides WARN_ON it only adds a tiny debug check.
Include this check unconditionally.Signed-off-by: Michael Buesch

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.By default all files without license information are under the default
license of the kernel, which is GPL version 2.Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if

There is code in ssb fetching "invariants" that is basically a set of
board specific data. Every host requires its own implementation of
reading function. In ssb we have support for PCI, PCMCIA & SDIO.
For some (historical?) reason code reading "invariants" for SoC was
placed in arch code and provided by a callback. This is not needed
nowadays, so lets move that into ssb. This way we keep all "invariants"
functions in a single module making code cleaner.Signed-off-by: Rafał Miłecki

ssb bus can be found on various "host" devices like PCI/PCMCIA/SDIO.
Every ssb bus contains cores AKA devices.
The main idea is to have ssb driver scan/initialize bus and register
ready-to-use cores. This way ssb drivers can operate on a single core
mostly ignoring underlaying details.For some reason PCMCIA support was split between ssb and b43. We got
PCMCIA host device probing in b43, then bus scanning in ssb and then
wireless core probing back in b43. The truth is it's very unlikely we
will ever see PCMCIA ssb device with no 802.11 core but I still don't
see any advantage of the current architecture.With proposed change we get the same functionality with a simpler
architecture, less Kconfig symbols, one killed EXPORT and hopefully
cleaner b43. Since b43 supports both: ssb & bcma I prefer to keep ssb
specific code in ssb driver.This mostly moves code from b43's pcmcia.c to bridge_pcmcia_80211.c. We
already use similar solution with b43_pci_bridge.c. I didn't use "b43"
in name of this new file as in theory any driver can operate on wireless
core.Signed-off-by: Rafał Miłecki

Pull MIPS updates from Ralf Baechle:
"The MIPS bits for 3.8. This also includes a bunch fixes that were
sitting in the linux-mips.org git tree for a long time. This pull
request contains updates to several OCTEON drivers and the board

updates to the SSB bus support, MIPS kexec code and adds support for
kdump.When pulling this, there are two expected merge conflicts in
include/linux/bcma/bcma_driver_chipcommon.h which are trivial to
resolve, just remove the conflict markers and keep both alternatives."* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (90 commits)

Some embedded devices like the Netgear WNDR3300 have two SSB based cards
without an own sprom on the pci bus. We have to provide two different
fallback sproms for these and this was not possible with the old solution.
In the bcm47xx architecture the sprom data is stored in the nvram in the
main flash storage. The architecture code will be able to fill the sprom
with the stored data based on the bus where the device was found.The bcm63xx code should do the same thing as before, just using the new
API.Acked-by: Michael Buesch

SSB is an SoC bus used in a number of embedded devices. The most
well-known of these devices is probably the Linksys WRT54G, but there
are others as well. The bus is also used internally on the BCM43xx
and BCM44xx devices from Broadcom.This patch also includes support for SSB ID tables in modules, so
that SSB drivers can be loaded automatically.Signed-off-by: Michael Buesch
