Some of TOMOYO's functions may sleep after mutex_lock(). If OOM-killer selected
a process which is waiting at mutex_lock(), the to-be-killed process can't be
killed. Thus, replace mutex_lock() with mutex_lock_interruptible() so that the
to-be-killed process can immediately return from TOMOYO's functions.

Errors from construct_alloc_key() shouldn't just be ignored in the way they are
by construct_key_and_link().  The only error that can be ignored so is
EINPROGRESS as that is used to indicate that we've found a key and don't need
to construct one.

We don't, however, handle ENOMEM, EDQUOT or EACCES to indicate allocation
failures of one sort or another.

Commit 6bfff31e (libata: kill probe_ent

Commits 9363c382 (libata: rename SFF

SFF port ops) renamed the taskfile access methods but didn't update the
developer's guide.  Commit c9f75b04
(libata: kill ata_noop_dev_select()) didn't update the developer's
guide as well.

The guide also refers to the long gone ata_pio_data_xfer_noirq(),

the modern ata_sff_data_xfer_noirq(), ata_sff_data_xfer(), and

call_sbin_request_key() creates a keyring and then attempts to insert a link to
the authorisation key into that keyring, but does so without holding a write
lock on the keyring semaphore.

It will normally get away with this because it hasn't told anyone that the
keyring exists yet.  The new keyring, however, has had its serial number
published, which means it can be accessed directly by that handle.

This was found by a previous patch that adds RCU lockdep checks to the code
that reads the keyring payload pointer, which includes a check that the keyring
semaphore is actually locked.

Without this patch, the following command:

	keyctl request2 user b a @s

will provoke the following lockdep warning is displayed in dmesg:

find_keyring_by_name() can gain access to a keyring that has had its reference

This problem is that find_keyring_by_name does not confirm that the keyring is
valid before accepting it.

Skipping keyrings that have been reduced to a zero count seems the way to go.
To this end, use atomic_inc_not_zero() to increment the usage count and skip
the candidate keyring if that returns false.

The following script _may_ cause the bug to happen, but there's no guarantee
as the window of opportunity is small:

	#!/bin/sh
	LOOP=100000
	USER=dummy_user
	/bin/su -c "exit;" $USER || { /usr/sbin/adduser -m $USER; add=1; }
	for ((i=0; i<LOOP; i++))
	do
		/bin/su -c "echo '$i' > /dev/null" $USER
	done
	(( add == 1 )) && /usr/sbin/userdel -r $USER
	exit

Note that the nominated user must not be in use.

An alternative way of testing this may be:

	for ((i=0; i<100000; i++))
	do
		keyctl session foo /bin/true || break
	done >&/dev/null

as that uses a keyring named "foo" rather than relying on the user and
user-session named keyrings.

We should disable irqs when we take the tu->qlock because it is used in
the irq handler.  The only place that doesn't is
snd_timer_user_ccallback().  Most of the time snd_timer_user_ccallback()
is called with interrupts disabled but the the first ti->ccallback()
call in snd_timer_notify1() has interrupts enabled.

This was caught by lockdep which generates the following message:

The OR verified that using the olpc-xo-1_5 model quirk allows the
headphones to be audible when inserted into the jack. Capture was
also verified to work correctly.

  KEYS: Fix RCU handling in key_gc_keyring()
  KEYS: Fix an RCU warning in the reading of user keys

key_gc_keyring() needs to either hold the RCU read lock or hold the keyring
semaphore if it's going to scan the keyring's list.  Given that it only needs
to read the key list, and it's doing so under a spinlock, the RCU read lock is
the thing to use.

Furthermore, the RCU check added in e7b0a61b is
incorrect as holding the spinlock on key_serial_lock is not grounds for
assuming a keyring's pointer list can be read safely.  Instead, a simple
rcu_dereference() inside of the previously mentioned RCU read lock is what we
want.

The ACPI dependency moved to the TPM, where it belongs.  Although
IMA per-se does not require access to the bios measurement log,
verifying the IMA boot aggregate does, which requires ACPI.

This patch pushes the ACPI dependency into the device driver code
itself. Now, even without ACPI/PNP enabled, the device can be registered
using the TIS specified memory space. This will however result in the
lack of access to the bios event log, being the only implication of such
ACPI removal.
