- adds a few missing slashes at the end of URLs.
- adds a few references to additional documentation.
- adds "make config" to the list of possible configuration targets.
- makes a few other minor changes.

Here's a patch that cleans up the "make help" output a bit for the
documentation targets.
Currently the documentation targets are listed completely different than
all the other targets :
Documentation targets:
Linux kernel internal documentation in different formats:
xmldocs (XML DocBook), psdocs (Postscript), pdfdocs (PDF)
htmldocs (HTML), mandocs (man pages, use installmandocs to install)
with this patch they are more in line with the rest of the output :
Documentation targets:
Linux kernel internal documentation in different formats:
htmldocs - HTML
installmandocs - install man pages generated by mandocs
mandocs - man pages
pdfdocs - PDF

Any code that relies on the volatile would be a bug waiting to happen
anyway.
Don't encourage people to think that putting 'volatile' on data
structures somehow fixes problems. We should always use proper locking
(and other serialization) techniques.

This is a resubmission of patches originally created by Ingo Molnar.
The link below is the initial (?) posting of the patch.
http://marc.theaimsgroup.com/?l=linux-kernel&m=115217423929806&w=2
Remove 'volatile' from spinlock_types as it causes GCC to generate bad
code (see link) and locking should be used on kernel data.

__do_IRQ() is needed only by irq handlers that can't use
default handlers defined in kernel/irq/chip.c.
For others platforms there's no need to compile this function
since it won't be used. For those platforms this patch defines
GENERIC_HARDIRQS_NO__DO_IRQ symbol which is used exactly for
this purpose.
Futhermore for platforms which do not use __do_IRQ(), end()
method which is part of the 'irq_chip' structure is not used.
This patch simply removes this method in this case.

I was playing with blackfin when i hit a neat bug ... doing an open() on a
directory and then passing that fd to mmap() would cause the kernel to hang
after poking into the code a bit more, i found that
mm/nommu.c:validate_mmap_request() checks the length and if it is 0, just
returns the address ... this is in stark contrast to mmu's
mm/mmap.c:do_mmap_pgoff() where it returns -EINVAL for 0 length requests ...
i then noticed that some other parts of the logic is out of date between the
two funcs, so perhaps that's the easy fix ?

The following moves the creation of IPR interupts into setup-7750.c
and updates a few other things to make it all work after the "Drop
CPU subtype IRQ headers" commit. It boots and runs fine on my titan
board.
- adds an ipr_idx to the ipr_data and uses a function in the subtype
code to calculate the address of the IPR registers
- adds a function to enable individual interrupt mode for externals
in the subtype code and calls that from the titan board code
instead of doing it directly.
- I changed the shift in the ipr_data to be the actual # of bits to
shift, instead of the numnber / 4 - made it easier to match with
the manual.

gcc4 gets a bit pissy about the outputs:

include/asm/atomic.h:37: error: invalid lvalue in asm statement

Since all of the sys_timer sources currently do this on their own
within the ->get_offset() path, it's more sensible to just have
the caller take care of it when grabbing xtime_lock. Incidentally,
this is more in line with what others (ie, ARM) are doing already.

Previously this was using a static pgd shift in the reporting
code, simply flip this to PGDIR_SHIFT which does the right
thing depending on varying PTE magnitudes on the SH-X2 MMU.
While we're at it, and since it's been recently added, use
get_TTB() for fetching the TTB, rather than the open coded
instructions.

The end of the store queue bitmap is miscalculated when searching
for a free range in sq_remap(), missing the PAGE_SHIFT shift that's
done in sq_api_init(). This runs in to workloads where we can scan
beyond the end of the bitmap.

This makes the early printk support somewhat more flexible,
moving the port definition to a config option, and making the
port initialization configurable for sh-ipl+g users.
At the same time, this allows us to trivially wire up the
SH7780 SCIF0, so that's thrown in too more or less for free.

There were a number of places that made evil PAGE_SIZE == 4k
assumptions that ended up breaking when trying to play with
8k and 64k page sizes, this fixes those up.
The most significant change is the way we load THREAD_SIZE,
previously this was done via:
mov #(THREAD_SIZE >> 8), reg
shll8 reg
to avoid a memory access and allow the immediate load. With
a 64k PAGE_SIZE, we're out of range for the immediate load
size without resorting to special instructions available in
later ISAs (movi20s and so on). The "workaround" for this is
to bump up the shift to 10 and insert a shll2, which gives a
bit more flexibility while still being much cheaper than a
memory access.

This extends the SH DMA API for allowing handling of DMA
channels based off of their respective capabilities.
A couple of functions are added to the existing API,
the core bits are register_chan_caps() for registering

a channel dynamically based off of a capability set.

Pass along the dev_id from request_dma() all the way down,
