This is a first cut at making the AT91 code use the generic GPIO calls.

Note that the original AT91 GPIO calls merged the "mux pin as GPIO" and "set
GPIO direction" functionality into one API call, contrary to what's specified
as a cross-platform portable model.  So this involved a few non-inlinable
functions.

This defines a simple and minimalist programming interface for GPIO APIs:

  - Documentation/gpio.txt ... describes things (read it)

  - include/asm-arm/gpio.h ... defines the ARM hook, which just punts
    to <asm/arch/gpio.h> for any implementation

  - include/asm-generic/gpio.h ... implement "can sleep" variants as calling
    the normal ones, for systems that don't handle i2c expanders.

The immediate need for such a cross-architecture API convention is to support
drivers that work the same on AT91 ARM and AVR32 AP7000 chips, which embed many
of the same controllers but have different CPUs.  However, several other users
have been reported, including a driver for a hardware watchdog chip and some
handhelds.org multi-CPU button drivers.

This is an attempt of providing an interface for memory scrubbing control in
EDAC.

This patch modifies the EDAC Core to provide the Interface for memory
controller modules to implment.

The following things are still outstanding:

 - K8 is the first implemenation,

   The patch provide a method of configuring the K8 hardware memory scrubber
   via the 'mcX' sysfs directory.  There should be some fallback to a generic
   scrubber implemented in software if the hardware does not support
   scrubbing.

   Or .. the scrubbing sysfs entry should not be visible at all.

 - Only works with SDRAM, not cache,

   The K8 can scrub cache and l2cache also - but I think this is not so
   useful as the cache is busy all the time (one hopes).

   One would also expect that cache scrubbing requires hardware support.

 - Error Handling,

   I would like that errors are returned to the user in "terms of file
   system".

 - Presentation,

   I chose Bandwidth in Bytes/Second as a representation of the scrubbing
   rate for the following reasons:

   I like that the sysfs entries are sort-of textual, related to something
   that makes sense instead of magical values that must be looked up.

   "My People" wants "% main memory scrubbed per hour" others prefer "%
   memory bandwidth used" as representation, "bandwith used" makes it easy to
   calculate both versions in one-liner scripts.

   If one later wants to scrub cache, the scaling becomes wierd for K8
   changing from "blocks of 64 byte memory" to "blocks of 64 cache lines" to
   "blocks of 64 bit".  Using "bandwidth used" makes sense in all three cases,
   (I.M.O.  anyway ;-).

 - Discovery,

   There is no way to discover the possible settings and what they do
   without reading the code and the documentation.

   *I* do not know how to make that work in a practical way.

 - Bugs(??),

   other tools can set invalid values in the memory scrub control register,
   those will read back as '-1', requiring the user to reset the scrub rate.
   This is how *I* think it should be.

 - Afflicting other areas of code,

   I made changes to edac_mc.c and edac_mc.h which will show up globally -
   this is not nice, it would be better that the memory scrubbing fuctionality
   and interface could be entirely contained within the memory controller it
   applies to.

edac_mc.c and its .h file is a CORE helper module for EDAC
driver modules. This provides the abstraction for device specific
drivers. It is fine to modify this CORE to provide help for
new features of the the drivers

Of kernel subsystems that work with pids the tty layer is probably the largest
consumer.  But it has the nice virtue that the assiation with a session only
lasts until the session leader exits.  Which means that no reference counting
is required.  So using struct pid winds up being a simple optimization to
avoid hash table lookups.

In the long term the use of pid_nr also ensures that when we have multiple pid
spaces mixed everything will work correctly.

Every call to is_orphaned_pgrp passed in process_group(current) which is racy
with respect to another thread changing our process group.  It didn't bite us
because we were dealing with integers and the worse we would get would be a
stale answer.

In switching the checks to use struct pid to be a little more efficient and
prepare the way for pid namespaces this race became apparent.

So I simplified the calls to the more specialized is_current_pgrp_orphaned so
I didn't have to worry about making logic changes to avoid the race.

To properly implement a pid namespace I need to deal exclusively in terms of
struct pid, because pid_t values become ambiguous.

To this end session_of_pgrp is transformed to take and return a struct pid
pointer.  To avoid the need to worry about reference counting I now require my
caller to hold the appropriate locks.  Leaving callers repsonsible for
increasing the reference count if they need access to the result outside of
the locks.

Since session_of_pgrp currently only has one caller and that caller simply
uses only test the result for equality with another process group, the locking
change means I don't actually have to acquire the tasklist_lock at all.

tiocspgrp is also modified to take and release the lock.  The logic there is a
little more complicated but nothing I won't need when I convert pgrp of a tty
to a struct pid pointer.

The aim of this patch set is to start wrapping up the struct pid conversions.
As such this patchset culminates with the removal of kill_pg, kill_pg_info,
__kill_pg_info, do_each_task_pid, and while_each_task_pid.

kill_proc, daemonize, and kernel_thread are still in my sights but there is
still work to get to them.

The first three are basic cleanups around disassociate_ctty, while working on
converting it I found several issues.  tty_old_pgrp can be a tricky concept to
wrap your head around.

 1 tty: Make __proc_set_tty static.
 2 tty: Clarify disassociate_ctty
 3 tty: Fix the locking for signal->session in disassociate_ctty

These just stop using the old helper functions.

 4 signal: Use kill_pgrp not kill_pg in the sunos compatibility code.
 5 signal: Rewrite kill_something_info so it uses newer helpers.

Then the grind to convert the tty layer and all of it's helper functions to
struct pid.

 6 pid: Make session_of_pgrp use struct pid instead of pid_t.
 7 pid: Use struct pid for talking about process groups in exit.c
 8 pid: Replace is_orphaned_pgrp with is_current_pgrp_orphaned
 9 tty: Update the tty layer to work with struct pid.

A final helper function update.

10 pid: Replace do/while_each_task_pid with do/while_each_pid_task

And the removal of the functions that are now unused.
11 pid: Remove now unused do_each_task_pid and while_each_task_pid
12 pid: Remove the now unused kill_pg kill_pg_info and __kill_pg_info

All of these should be fairly simple and to the point.

This patch:

Currently all users of __proc_set_tty are in tty_io.c so make the function
static.

This adds a new "wakealarm" sysfs attribute to RTC class devices which support
alarm operations and are wakeup-capable:

 - It reads as either empty, or the scheduled alarm time as seconds
   since the POSIX epoch.  (That time may already have passed, since
   nothing currently enforces one-shot alarm semantics.)

 - It can be written with an alarm time in the future, again seconds
   since the POSIX epoch, which enables the alarm.

 - It can be written with an alarm time not in the future (such as 0,
   the start of the POSIX epoch) to disable the alarm.

Usage examples (some need GNU date) after "cd /sys/class/rtc/rtcN":

    alarm after 10 minutes:
	# echo $(( $(cat since_epoch) + 10 * 60 )) > wakealarm
    alarm tuesday evening 10pm:
	# date -d '10pm tuesday' "+%s" > wakealarm
    disable alarm:
    	# echo 0 > wakealarm

This resembles the /proc/acpi/alarm file in that nothing happens when the
alarm triggers ...  except possibly waking the system from sleep.  It's also
like that in a nasty way: not much can be done to prevent one task from
clobbering another task's alarm settings.

It differs from that file in that there's no in-kernel date parser.

Note that a few RTCs ignore rtc_wkalrm.enabled when setting alarms, or aren't
set up correctly, so they won't yet behave with this attribute.

Granted, the function replacing it must call spi_bitbang_setup_transfer,

This adds a SPI driver for the Microwire controller on OMAP1 chips.  This
driver has been used in the Linux-OMAP tree for some time now, including
with some of those displays using standardized 9-bit commands followed by
data with 8-bit words.

Microwire only supports half duplex transfers, but that's all that most SPI
protocols need.  When full duplex, or higher speeds, are needed there are
several other controllers that can be used on OMAP.

- Use timer macros to set function and data members and to modify
  expiration time.
- Use DEFINE_TIMER for global timers and do not init them at run-time in
  these cases.
- del_timer_sync is common in most cases -- we want to wait for timer
  function if it's still running.
