USB: Fix race condition when removing host controllers
This patch (as1607) fixes a race that can occur if a USB host
controller is removed while a process is reading the
/sys/kernel/debug/usb/devices file.
The usb_device_read() routine uses the bus->root_hub pointer to
determine whether or not the root hub is registered. The is not a
valid test, because the pointer is set before the root hub gets
registered and remains set even after the root hub is unregistered and
deallocated. As a result, usb_device_read() or usb_device_dump() can
access freed memory, causing an oops.
The patch changes the test to use the hcd->rh_registered flag, which
does get set and cleared at the appropriate times. It also makes sure
to hold the usb_bus_list_lock mutex while setting the flag, so that
usb_device_read() will become aware of new root hubs as soon as they
are registered.

m68knommu: clean up ColdFire 54xx General Timer definitions
Convert the ColdFire 54xx CPU General Timer register address definitions to
include the MCF_MBAR peripheral region offset. This makes them consistent
with all other 54xx address register definitions (in m54xxsim.h).
The goal is to reduce different definitions used (some including offsets and
others not) causing bugs when used incorrectly.
m68knommu: clean up Pin Assignment definitions for the 54xx ColdFire CPU
The Pin Assignment register definitions for the ColdFire 54xx CPU family are
inconsistently named and defined compared to the other ColdFire part
definitions. Rename them with the same prefix as used on other parts,
MCFGPIO_PAR_, and make their definitions include the MCF_MBAR periphperal
region offset.
m68knommu: fix multi-function pin setup for FEC module on ColdFire 523x
The multi-function pin setup code for the FEC ethernet module is using just
plain wrong. Looks like it was cut-and-pasted from other init code. It has
hard coded register addresses that are incorrect for the 523x, and it is
manipulating bits that don't make sense.
Add proper register definitions for the Pin Assignment registers of the 532x,
and then use them to fix the setup code for the FEC hardware module.
m68knommu: move ColdFire slice timer address defiens to 54xx header
Move the base address defines of the ColdFire 54xx CPU slice timers into the
54xx specific header (m54xxsim.h). They are CPU specific, and belong with the
CPU specific defines. Also make them relative to the MBAR peripheral region,
making the define the absolute address.
m68knommu: use read/write IO access functions in ColdFire m532x setup code
Get rid of the use of local IO access macros and switch to using the standard
read*/write* family of access functions for the ColdFire m532x setup code.
m68knommu: modify ColdFire 532x GPIO register definitions to be consistent
The ColdFire 532x CPU register definitions for the multi-function setup
pins are inconsistently defined compared with other ColdFire parts. Modify
the register defintions to be just the addresses, not pointers. This also
fixes the erroneous use in one case of using these values in the UART setup
code for the 532x.
m68knommu: use definitions for the ColdFire 528x FEC multi-function pins
Currently the setup code for the FEC multi-function pins on the ColdFire 528x
has the addresses hard coded in the code. Use the register defines that
already exist for this.
m68knommu: remove address offsets relative to IPSBAR for ColdFire 527x
Remove the last address definitions relative to the IPSBAR peripheral region
for the ColdFire 527x family. This involved cleaning up some magic numbers
used in the code part, and making them proper register definitions in the 527x
specific header.
This is part of the process of cleaning up the ColdFire register definitions
to make them consistently use absolute addresses for the primary registers.
This will reduce the occasional bugs caused by inconsistent definition of
the register addresses.
m68knommu: fix wrong register offsets used for ColdFire 5272 multi-function pins
The registers used to configure and set the multifunction pins on the 5272
ColdFire are defined as absolute addresses. So the use of them does not need
to be offset relative to the peripheral region address.
Fix two cases of incorrect usage of these addresses. Both affect UART
initialization, one in the common UART pin setup code, the other in the
NETtel board specific UART signal handling.
m68knommu: make ColdFire 5249 MBAR2 register definitions absolute addresses
Make the ColdFire 5249 MBAR peripheral register definitions absolute
addresses, instead of offsets into the region.
The various ColdFire parts use different methods to address the internal
registers, some are absolute, some are relative to peripheral regions
which can be mapped at different address ranges (such as the MBAR and IPSBAR
registers). We don't want to deal with this in the code when we are
accessing these registers, so make all register definitions the absolute
address - factoring out whether it is an offset into a peripheral region.
This makes them all consistently defined, and reduces the occasional bugs

jbd2: fix assertion failure in commit code due to lacking transaction credits
ext4 users of data=journal mode with blocksize < pagesize were
occasionally hitting assertion failure in
jbd2_journal_commit_transaction() checking whether the transaction has
at least as many credits reserved as buffers attached. The core of the
problem is that when a file gets truncated, buffers that still need
checkpointing or that are attached to the committing transaction are
left with buffer_mapped set. When this happens to buffers beyond i_size
attached to a page stradding i_size, subsequent write extending the file
will see these buffers and as they are mapped (but underlying blocks
were freed) things go awry from here.
The assertion failure just coincidentally (and in this case luckily as
we would start corrupting filesystem) triggers due to journal_head not
being properly cleaned up as well.
We fix the problem by unmapping buffers if possible (in lots of cases we
just need a buffer attached to a transaction as a place holder but it
must not be written out anyway). And in one case, we just have to bite
the bullet and wait for transaction commit to finish.
