This gets caught by the new sanity check code. Instead of the slash use a
different symbol. This was originally found by Major Lee who proposed a
rather more complex patch which changed the name according to the chip
type.

On the basis that we are in a late -rc and making Linus grumpy isn't always
a good idea (however fun) this is a simple alternative.

Cache ownership must be acquired by reading/writing data from the
cache line to make cache operation have the desired effect on the
SMP MPCore CPU. However, the ownership is never acquired in the
v6_dma_inv_range function when cleaning the first line and
flushing the last one, in case the address is not aligned
to D_CACHE_LINE_SIZE boundary.
Fix this by reading/writing data if needed, before performing
cache operations.
While at it, fix v6_dma_flush_range to prevent RWFO outside
the buffer.

Because the nwfpe support is unlikely to be used on new platforms
and requires CONFIG_OABI_COMPAT, which is not generally used with
ARMv7+, we shouldn't expect to build nwfpe support into a Thumb-2
kernel.

At present, nwfpe contains assembly code which isn't Thumb-2
compatible, and for now it doesn't appear useful to port this
code.

All ARMv7-A/R platforms necessarily have VFPv3 hardware floating-
point natively, making emulation unnecessary.

This makes sense, because Thumb-2 code can't execute on plain
ARMv6 processors.

This will avoid accidentally configuring a broken kernel where the
config otherwise would allow multiple architecture versions to
coexist in the same kernel.

Not adding !CPU_V5 etc., because the chance of anyone trying to
put v5 and v7 in the same kernel is low, and I'm not aware of
any mach which can do this.  These could be added later if it
matters.

Note that the rules may need to be refined if support for the
ARM1156J(F)-S processor is later added to the kernel, since this
processor supports the rare ARMv6T2 extensions, which add support
for Thumb-2 and a few other ARMv7 features.

Running the annotate branch profiler on three boxes, including my
main box that runs firefox, evolution, xchat, and is part of the distcc farm,
showed this with the likelys in the workqueue code:

 correct incorrect  %        Function                  File              Line
 ------- ---------  -        --------                  ----              ----
      96   996253  99 wq_worker_sleeping             workqueue.c          703
      96   996247  99 wq_worker_waking_up            workqueue.c          677

The likely()s in this case were assuming that WORKER_NOT_RUNNING will
most likely be false. But this is not the case. The reason is
(and shown by adding trace_printks and testing it) that most of the time
WORKER_PREP is set.

In worker_thread() we have:

	worker_clr_flags(worker, WORKER_PREP);

	[ do work stuff ]

	worker_set_flags(worker, WORKER_PREP, false);

(that 'false' means not to wake up an idle worker)

The wq_worker_sleeping() is called from schedule when a worker thread
is putting itself to sleep. Which happens most of the time outside
of that [ do work stuff ].

The wq_worker_waking_up is called by the wakeup worker code, which
is also callod outside that [ do work stuff ].

Thus, the likely and unlikely used by those two functions are actually
backwards.

Remove the annotation and let gcc figure it out.

Refresh rate nearness is not calculated or reset when nearest resolution
changes.

This patch resets the refresh rate differential measurement whenever a
new nearest resolution is discovered.  This fixes two error cases;
first, wherein the first mode's refresh rate differential is never
calculated and second, when the closest refresh rate from a previous
nearest resolution is erroneously preserved.

The commit 111c1823 (kgdboc: reset
input devices (keyboards) when exiting debugger) introduced a
regression in early debugging such that you get a kernel oops on
continue (with the go command) if you boot a kernel with:

    earlyprintk=vga ekgdboc=kbd kgdbwait

The restore kgdboc_restore_input() routine schedules work for the
purpose of sending key release events for any keys that were in the
depressed state prior to entering the kernel debugger.  A simple fix
to the crash is to not invoke the schedule_work() if the kernel
system_state is anything other than SYSTEM_RUNNING.
