Query the status bit every time we need it instead.
We need to export another function to query for USB presence because
we can't read anything from PCF50633 (via I2C) inside irq context and
that is needed by usb gadgets.

Basic Mode is the default mode of operation of a L2CAP entity. In
this case the RFC (Retransmission and Flow Control) configuration
option should not be used at all.
Normally remote L2CAP implementation should just ignore this option,
but it can cause various side effects with other Bluetooth stacks
that are not capable of handling unknown options.

If chgmod == BATFULL, setting chgena has no effect. Datasheet says we
need to set resume instead but when autoresume is used resume doesn't
work. Clear and set chgena instead.
This enables a user to force charging by re-plugging USB even when the
charger entered Battery Full mode, might be handy before a long trip.

After reaching Battery Full condition MBC state machine switches back
into charging mode when the battery voltage falls below 96% of a
battery float voltage. The voltage drop in Li-Ion batteries is
marginal (1-2%) till about 80% of its capacity - which means, after a
BATFULL, charging won't be restarted until 75-80%.
That is a desired behaviour recommended by battery manufacturers,
don't mess with it.

This patch fixes double pairing issues with Secure Simple
Paring support. It was observed that when pairing with SSP
enabled, that the confirmation will be asked twice.
http://www.spinics.net/lists/linux-bluetooth/msg02473.html
This also causes bug when initiating SSP connection from
Windows Vista.
The reason is because bluetoothd does not store link keys
since HCIGETAUTHINFO returns 0. Setting default to general
bonding fixes these issues.

Implement a new sysfs attribute to allow changing MBC charging limit on
the fly independently of usb current limit. It also gets set
automatically every time usb current limit is changed.
Limiting charging current also prevents violating USB specification in
the case when the whole device is shut down and usb current limit is
reset to the factory default by the pcf50633 state transition.

When an inode gets unlinked, the functions ext4_clear_blocks() and
ext4_remove_blocks() call ext4_forget() for all the buffer heads
corresponding to the deleted inode's data blocks. If the inode is a
directory or a symlink, the is_metadata parameter must be non-zero so
ext4_forget() will revoke them via jbd2_journal_revoke(). Otherwise,
if these blocks are reused for a data file, and the system crashes
before a journal checkpoint, the journal replay could end up
corrupting these data blocks.
Thanks to Curt Wohlgemuth for pointing out potential problems in this
area.

Now that we are checking for failed journal checksums in the jbd2
layer, we don't need to check in the ext4 mount path --- since a
checksum fail will result in ext4_load_journal() returning an error,
causing the file system to refuse to be mounted until e2fsck can deal
with the problem.
Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
If there is a failed journal checksum, don't reset the journal. This
allows for userspace programs to decide how to recover from this
situation. It may be that ignoring the journal checksum failure might
be a better way of recovering the file system. Once we add per-block
checksums, we can definitely do better. Until then, a system
administrator can try backing up the file system image (or taking a
snapshot) and and trying to determine experimentally whether ignoring
the checksum failure or aborting the journal replay results in less
data loss.

In finish_task_switch(), fire_sched_in_preempt_notifiers() is
called after finish_lock_switch().
However, depending on architecture, preemption can be enabled after
finish_lock_switch() which breaks the semantics of preempt
notifiers.
So move it before finish_arch_switch(). This also makes the in-
notifiers symmetric to out- notifiers in terms of locking - now
both are called under rq lock.
