The conversion did not make use of the new chip flag which signals the
core code to mask the chip before calling the set_type callback. Sigh.
Use the new lockdep helper as well.

Currently there is one irq_chip per gpio_chip with the only difference
being the name. Since the information whether the irq belong to GPIO
bank A, B, C or D is not that important rewrite the code to simply use
a single irq_chip for all gpio_chips.

Fix the deadlock in set_type() while at it:
The code called set_irq_chip_and_handler_name() resp. set_irq_chip()
from the set_type() callback. That only works on UP and lock debugging
disabled. Otherwise it would dead lock on desc->lock.
__irq_set_chip_handler_name_locked() avoids that.

Some of MSP family SoC's come with legacy 100Mbps mspeth while some comes
with newer Gigabit TSMAC.Following patch adds platform support for both
types of MAC's.
If TSMAC is not selected assume platform having legacy mspeth. Add
gpio_macros as well which is required for resetting the PHY.

is per irq and not per chip. Allow them to provide a chip callback to
print the chip name and the extra information.
PowerPC wants to print the LEVEL/EDGE type information. Make it configurable.

When the queue work handler was converted to delayed work, the
stopping was inadvertently made sync as well. Change this back
to being async stop, using __cancel_delayed_work() instead of

With the introduction of the on-stack plugging, we would assume
that any request being inserted was a normal file system request.
As flush/fua requires a special insert mode, this caused problems.
Fix this up by checking for this in flush_plug_list() and use
the appropriate insert mechanism.
Big thanks goes to Markus Tripplesdorf for tirelessly testing
patches, and to Sergey Senozhatsky for helping find the real
issue.

An update of the futex code had a
WARN_ON(!spin_is_locked(q->lock_ptr))
But on UP, spin_is_locked() is always false, and will
trigger this warning, and even worse, it will exit the function
without doing the necessary work.
Converting this to a WARN_ON_SMP() fixes the problem.

Both WARN_ON() and WARN_ON_SMP() should be able to be used in
an if statement.
if (WARN_ON_SMP(foo)) { ... }
Because WARN_ON_SMP() is defined as a do { } while (0) on UP,
it can not be used this way.
Convert it to the same form that WARN_ON() is, even when
CONFIG_SMP is off.

Eric Dumazet reported that hardware PMU events do not work on his
system, due to the BIOS corrupting PMU state:
Performance Events: PEBS fmt0+, Core2 events, Broken BIOS detected, using software events only.
[Firmware Bug]: the BIOS has corrupted hw-PMU resources (MSR 186 is 43003c)
Linus suggested that we continue in the face of such BIOS-induced CPU
state corruption:
http://lkml.org/lkml/2011/3/24/608
Such BIOSes will have to be fixed - Linux developers rely on a working and
fully capable PMU and the BIOS interfering with the CPU's PMU state is simply
not acceptable.
So this patch changes perf to continue when it detects such BIOS
interaction, some hardware events may be unreliable due to the BIOS
writing and re-writing them - there's not much the kernel can do
about that but to detect the corruption and report it.

There is a lot of common code that could be shared between the m68k
and m68knommu arch branches. It makes sense to merge the two branches
into a single directory structure so that we can more easily share
that common code.
This is a brute force merge, based on a script from Stephen King
<sfking@fdwdc.com>, which was originally written by Arnd Bergmann
<arnd@arndb.de>.
> The script was inspired by the script Sam Ravnborg used to merge the

On top of this file merge I have done a simplistic merge of m68k and
m68knommu Kconfig, which primarily attempts to keep existing options and
menus in place. Other than a handful of options being moved it produces
identical .config outputs on m68k and m68knommu targets I tested it on.
With this in place there is now quite a bit of scope for merge cleanups
in future patches.
