[Blackfin] arch: relocate MAX_SWITCH_{D,I}_CPLBS from the header to the file where it actually gets used.

relocate MAX_SWITCH_{D,I}_CPLBS from the header to the file
where it actually gets used.  this way when we change
CONFIG_MEM_SIZE in our kconfig, we only rebuild one or two files
rather than a whole bunch that implicitly include cplb.h.

this will also remove the ability to clear the swapcount on
the fly, but i really dont think that functionality is important.

ultimate goal is for CONFIG_MEM_SIZE to go away and calculate
this value on the fly based on what u-boot programmed for us.

replace implied numbers with real values so that strace is able to
calculate things automatically ... the numbers are frozen in our ABI,
so having them based off other __NR_xxx values really doesnt matter

Bug: CONFIG_MPU doesn't seem to handle access to ASYNC/IO Memory well

There were a couple of problems with the way the trace buffer state
is saved/restored in assembly.  The DEBUG_HWTRACE_SAVE/RESTORE macros
save a value to the stack, which is not immediately obvious; the CPLB
exception code needed changes to load the correct value of the stack
pointer.  The other problem is that the SAVE/RESTORE macros weren't
pushing and popping the value downwards on the stack, but rather moving
it _upwards_, which is of course completely broken.

We also need to make sure there's a matching DEBUG_HWTRACE_RESTORE in
the error case of the CPLB handler.

Since
  r3658 | vapier | 2007-09-12 16:26:11 +0200 (Wed, 12 Sep 2007) | 1 line

  add more common defines for output sections

we've had a new line, NOTES, in our linker script, which causes upstream
binutils to complain about "missing phdr".  Currently the only other arch
that uses NOTES is i386, and the patch which added it also added
PHDRS {
	text PT_LOAD FLAGS(5);	/* R_E */
	data PT_LOAD FLAGS(7);	/* RWE */
	note PT_NOTE FLAGS(0);	/* ___ */
}
and a few other modifications to use ":text" and ":data" to the linker
script.

It seems that we don't need NOTES at all, so just remove it.

PNP_MAX_IRQ is 2
If a device invokes pnpacpi_parse_allocated_irqresource() 0, 1, or 2 times, we are happy.
The 3rd time, we will fail and print "pnpacpi: exceeded the max number of IRQ resources: 2"
The 4th and subsequent calls (if this ever happened) would silently scribble on
irq_resource[2], which doesn't actualy exist.

The LEDS infrastructure itself does not require anything
that a platform dependant upon HAS_IOMEM.

The individual drivers do, but they are properly guarded
with the necessary platform dependencies.

One can even imagine a hypervisor based LED driver that
a platform without HAS_IOMEM might have.

[mszeredi@suse.cz] rewrite and split big patch into managable chunks

/proc/mounts in its current form lacks important information:

 - propagation state
 - root of mount for bind mounts
 - the st_dev value used within the filesystem
 - identifier for each mount and it's parent

It also suffers from the following problems:

 - not easily extendable
 - ambiguity of mountpoints within a chrooted environment
 - doesn't distinguish between filesystem dependent and independent options
 - doesn't distinguish between per mount and per super block options

This patch introduces /proc/<pid>/mountinfo which attempts to address
all these deficiencies.

Code shared between /proc/<pid>/mounts and /proc/<pid>/mountinfo is
extracted into separate functions.

Thanks to Al Viro for the help in getting the design right.
