Currently the udc pullup is enabled by default on boot. If the device
is connected to a host at this time, the host starts the negotiation
before the udc/gadget driver is ready to handle it.

Due to errata regarding the handling of SPI CS0 on the AT91RM9200, the
atmel_spi driver drives CS0 from the SPI controller and not as a GPIO
pin.
We therefore need to configure CS0 for use by the controller

Modify the UART initialization to allow the board-initialization code
to specify which pins are connected, and which pins should therefore
be initialized.

The current at91_init_serial() will continue to work as-is, but is
marked as "deprecated" and will be removed once the board-specific
files has been updated to use the new interface.

As in the AVR32 code, we assume that the TX and RX pins will always be
initialized.

This makes HZ configurable on AT91, following the model used on OMAP.

It defaults to a power of two on AT91rm9200 chips, avoiding rounding
errors which come from dividing a 32 KiHz clock to generate scheduler
irqs; and uses 100 on AT91sam926x chips, using MCK/16 (multi-MHZ).

If we know a buffer_head is non-null, then brelse() is unnecessary and
put_bh() can be used instead. Also, an explicit check for NULL is
unnecessary when using brelse(). This patch only covers buffer_head_io.c and
resize.c, which have recently added code which exhibits this problem.

Currently the process of dlm join contains 2 steps: query join and assert join.
After query join, the joined node will set its joining_node. So if the joining
node happens to panic before the 2nd step, the joined node will fail to clear
its joining_node flag because that node isn't in the domain map. It at least
cause 2 problems.
1. All the new join request will fail. So no new node can mount the volume.
2. The joined node can't umount the volume since during the umount process it
   has to wait for the joining_node to be unknown. So the umount will be hanged.

The solution is to clear the joining_node before we check the domain map.
