The mod_reg_security() function that is used to stack modules has been removed:
"LSMs wishing to stack capability as a secondary module should do so
explicitly". Thus, let's remove the possibility to stack in the init function.
The functionality could probably be reintroduced later if somebody has time to
implement it.

This is a patch that will reintroduce the old sysctl lowmem variables as read
only values in /proc/sys/vm. Some parts of the userland (at least libosso) are
reading these and it would probably greatly ease the transition to the new
scheme with memory limits in pages. We can revert this ugly patch when userland
has moved to the new scheme.

The unregister_security() and mod_unreg_security() functions were removed
because the upstream developers believe that it should not be possible to remove

This "changed" variable is kind of deprecated. We used to have a spinlock

The purpose of this patch is to get rid of the lame percentage calculations in
lowmem.c. Currently, the limits (measured in pages) are calculated from
percentages every time somebody from userspace requests some memory. With this
patch, the limits are in pages and furthermore, they are specified as minimum
amount of "free pages", instead of as maximum amount of "used pages". "Free"
means free pages or such pages that can easily be freed by the VM system.

This patch changes the names of the lowmem sysctl limits in /proc/sys/vm:
lowmem_deny_watermark  	     => lowmem_deny_watermark_pages
lowmem_notify_low	     => lowmem_notify_low_pages
lowmem_notify_high 	     => lowmem_notify_high_pages

The following read only value disappears:
lowmem_used_pages

The following read only value is introduced:
lowmem_free_pages

The old value can be calculated from userspace with the following pseudocode:

if lowmem_free_pages < lowmem_allowed_pages
   lowmem_used_pages = lowmem_allowed_pages - lowmem_free_pages
else
   lowmem_used_pages = 0;

Note that the value of lowmem_free_pages is only accurate when the system is
rather low on memory (otherwise it's a bit too pessimistic), this was true also
for the lowmem_used_pages metric.

Make the twl4030 RTC initialization follow the driver model better.
The platform device is created (if needed) as part of twl4030 setup
instead of as a board-specific thing, and fits properly into the
driver model tree.

The only minor glitch here is on boards using platform_data to pass
MSECURE initialization hooks to the RTC driver.  The right solution
probably just removes that platform_data, and might even make Linux
follow the principle of "least privilege" (at the hardware level!)
instead of always holding this signal high.

Pending better handling of MSECURE, this patch just does what the
RTC init does, but earlier:  MSECURE is always high, so the RTC time
and calendar registers can be updated (and presumably a bunch of
non-RTC privileged operations will be allowed too).

Yet to be done:  set up the IRQ resource; make the rtc driver use
that IRQ resource; and properly issue wakeup alarms.

Remove more bogus arch_initcall() logic in mach-omap2/board-xyx.c files.
They broke a multi-OMAP build I did, at *RUN TIME* not build time, since
it tried to do the i2c init for every board linked in the kernel.

Remember, init_machine() entries run at arch_initcall() time; that's
where any board-specific init logic should normally go.  Any initcalls
in the mach-*/*c files should normally be guarded by tests to make sure
they only run on the relevant hardware (board, cpu).  Better yet, get
rid of the initcalls; init_machine() can *explicitly* call the right
version of that code, and pass in board-specific config data; and there
are hooks that can handle cpu-specific stuff too.

A quick glance suggests most of the remaining initcall logic in the
mach-omap2 directory is similarly broken... this patch gets rid of
one frequently-cloned idiom, it should help.
