b4224b236b omap: Fix DEBUG_LL UART io address
This patch fixes the low level debug UART io address as per this series.
The change is essential to have CONFIG_DEBUG_LL working.

10db25fea4 omap: Remap L3, L4 to get more kernel io address space
This patch remap L3 and L4 io space to get more kernel address space.
With this patch, 512 MB of IO space is reclaimed.
Some more combinations are possible but to make it uniform across
OMAP24XX, OMAP34XX and OMAP4430, these io combinations are chosen

Once this is reviewed and tested sufficiently, a documentation entry can
be created to ease up reading and debugging.
Like "Documentation/arm/omap/io_map.txt"

233fd64e7f omap: Split OMAP2_IO_ADDRESS to L3 and L4
This patch splits OMAP2_IO_ADDRESS to OMAP2_L3_IO_ADDRESS and
OMAP2_L4_IO_ADDRESS to reclaim more IO space.

The omap_read*() and omap_write*() functions will work only over
L4 address space. Current omap kernel stack uses these functions
only to access registers over L4 io address space

Note that these macros should only be used when ioremap does
not work. Please use ioremap instead in all new code.

21279cfa10 KEYS: get_instantiation_keyring() should inc the keyring refcount in all cases
The destination keyring specified to request_key() and co. is made available to
the process that instantiates the key (the slave process started by
/sbin/request-key typically).  This is passed in the request_key_auth struct as
the dest_keyring member.

keyctl_instantiate_key and keyctl_negate_key() call get_instantiation_keyring()
to get the keyring to attach the newly constructed key to at the end of
instantiation.  This may be given a specific keyring into which a link will be
made later, or it may be asked to find the keyring passed to request_key().  In
the former case, it returns a keyring with the refcount incremented by
lookup_user_key(); in the latter case, it returns the keyring from the
request_key_auth struct - and does _not_ increment the refcount.

The latter case will eventually result in an oops when the keyring prematurely
runs out of references and gets destroyed.  The effect may take some time to
show up as the key is destroyed lazily.

To fix this, the keyring returned by get_instantiation_keyring() must always
have its refcount incremented, no matter where it comes from.

This can be tested by setting /etc/request-key.conf to:

#OP	TYPE	DESCRIPTION	CALLOUT INFO	PROGRAM ARG1 ARG2 ARG3 ...
#======	=======	===============	===============	===============================
create  *	test:*		*		|/bin/false %u %g %d %{user:_display}
negate	*	*		*		/bin/keyctl negate %k 10 @u

and then doing:

	keyctl add user _display aaaaaaaa @u
        while keyctl request2 user test:x test:x @u &&
        keyctl list @u;
        do
                keyctl request2 user test:x test:x @u;
                sleep 31;
                keyctl list @u;
        done

which will oops eventually.  Changing the negate line to have @u rather than
%S at the end is important as that forces the latter case by passing a special
keyring ID rather than an actual keyring ID.

This was broken by commit e9216651.

The compat_unimap_ioctl was originally called do_unimap_ioctl in

In that patch, the caller was not updated and consequently called

a0219fbdac OMAP: Fix race condition with autodeps
There is a possible race condition in clockdomain
code handling hw supported idle transitions.

When multiple autodeps dependencies are being added
or removed, a transition of still remaining dependent
powerdomain can result in false readings of the
state counter. This is especially fatal for off mode
state counter, as it could result in a driver not
noticing a context loss.

Fixed by disabling hw supported state transitions
when autodeps are being changed.
