Fix buggy-looking code which unnecessarily adjusts the file offset
fields read from /proc/*/maps.
This may have gone unnoticed since the offset is usually 0 (and the
logic in util/symbol.c may work incorrectly for other offset values).
Commiter note:
This fixes a bug introduced in 4af8b35, there is no need to shift pgoff
twice, the show_map_vma routine in fs/proc/task_mmu.c already converts
it from the number of pages to the size in bytes, and that is what
appears in /proc/PID/map.

Below you will find an updated version from the original series bunching all patches into one big patch
updating broken web addresses that are located in Documentation/*
Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult,
the best way to deal with these is to use web.archive.org to locate these addresses that are outdated.
Now there are also some addresses pointing to .spec files some are located, but some(after searching
on the companies site)where still no where to be found. In this case I just changed the address
to the company site this way the users can contact the company and they can locate them for the users.

We saw a report of a NULL dereference in xprt_autoclose:
https://bugzilla.redhat.com/show_bug.cgi?id=611938
This appears to be the result of an xprt's task_cleanup running after
the xprt is destroyed. Nothing in the current code appears to prevent
that.

Now that rpc_run_task() is the sole entry point for RPC calls, we can move
the remaining rpc_client-related initialisation of struct rpc_task from
sched.c into clnt.c.
Also move rpc_killall_tasks() into the same file, since that too is
relative to the rpc_clnt.

With this patch, you'll get the following sysfs directories. This
structure implies that a single platform device, "omap2-mailbox" holds
multiple logical mbox instances. This could be the base to add sysfs
files for each logical mboxes. Then userland application can access a
mbox through sysfs entries if necessary(ex: setting kfifo size
dynamically)
~# tree -d -L 2 /sys/devices/platform/omap2-mailbox/
/sys/devices/platform/omap2-mailbox/
|-- driver -> ../../../bus/platform/drivers/omap2-mailbox
|-- mbox
| |-- dsp <- they are each instances of logical mailbox.

The underlying buffering implementation of mailbox
is converted from block API to kfifo due to the simplicity
and speed of kfifo.
The default size of the kfifo buffer is set to 256 bytes.
This value is configurable at compile time (via
CONFIG_OMAP_MBOX_KFIFO_SIZE), and can be changed at
runtime (via the mbox_kfifo_size module parameter).

when blk_get_request fails to get the request it is returning
without read the message from the mailbox fifo, then when it
leaves the isr and interruption is trigger again and again and
the workqueue which get elements from the request queue is never
executed and the kernel is stuck and shows a softlockup message.
Now the mailbox interrupt is disabled when request queue is full
and enabled when it pop a elememt form the request queue.
