The platform code doesn't have to provide platform data to get sensible
default behaviour from the imx serial driver.
This patch does not handle NULL dereference in the IrDA case, which still
requires a valid platform data pointer (in imx_startup()/imx_shutdown()),
since I don't know whether there is a sensible default behaviour, or
should the operation just fail cleanly.

This patch is heavily based on an earlier patch found on the linux-serial
mailing list [1], written by Darius Augulis.
The previous incarnation of this patch only supported a 2x serial port
card. I have added support for my SYBA 6x serial port card, and tested on
x86.

Fix transmit bug that could drop send data if write() called close to
serial transmitter going idle after sending previous data. Bug is caused
by incorrect use of device information member tx_count.
Driver originally processed one data block (write call) at a time, waiting
for transmit idle before sending more. tx_count recorded how much data
was loaded in DMA buffers on write(), and was cleared on send completion.
tx_count use was overloaded to record accumulated data from put_char()
callback when transmitter was idle.
A bug was introduced when transmit code was reworked to allow multiple
blocks of data in the tx DMA buffers which keeps transmitter from going
idle between blocks. tx_count was set to size of last block loaded,
cleared when tx went idle, and monitored to know when to restart
transmitter without proper synchronization. tx_count could be cleared
when unsent data remained in DMA buffers and transmitter required
restarting, effectively dropping unsent data.
Solution:
1. tx_count now used only to track accumulated data from put_char
2. DMA buffer state tracked by direct inspection of descriptors
with spinlock synchronization
3. consolidate these tasks in tx_load() :
a. check for available buffer space
b. load buffers
c. restart DMA and or serial transmitter as needed
These steps were previously duplicated in multiple places,
sometimes incompletely.
4. fix use of tx_count as active transmit indicator,
instead using tx_active which is meant for that purpose

early_serial_setup
Augment the UPF_FIXED_TYPE logic, which currently applies to UART ports
provisioned using platform_device_register.
The suggested patch applies same logic into 'serial8250_register_ports',
making UART ports provisioned using early_serial_setup inherit their
properties from the uart_config entry.

Fit blackfin uart over sport driver into common uart inftrastructure. It
is based on the early platform interfaces to get the platform data early
when the console is initilized.
1. Enable sport uart driver to change uart baud, data bit, stop bit at
runtime. Bind the index of uart device nodes to physical index of
sports.
2. Move all platform data into arch specific board files. Register
and probe platform device data in both early and normal stages.
3. Console is registered in sport uart driver as well.
4. Remove 500 us block waiting in sport tx stop code by putting a
dummy data into tx fifo to make sure the sport tx stops when all bytes
are shifted out except for the dummy data.
5. clean up a bit and fix up coding style.

Currently we were adding ioctl cmds/structures for ocfs2 into ocfs2_fs.h
which was used for define ocfs2 on-disk layout. That sounds a little bit
confusing, and it may be quickly polluted espcially when growing the
ocfs2_info_request ioctls afterwards(it will grow i bet).
As a result, such OCFS2 IOCs do need to be placed somewhere other than
ocfs2_fs.h, a separated ocfs2_ioctl.h will be added to store such ioctl
structures and definitions which could also be used from userspace to
invoke ioctls call.

Audio Indigo soundcards
Indigos are well known for distortions when running on some buggy ENE
controllers. There is a workaround in the yenta driver, but for some
reason it isn't activated on CB712. However, I own a laptop with such
chip and it seems that it also is affected - I can clearly hear occasional
cracks, especially under heavy network load, and in Windows XP the card is
completely unusable.
This simple change fixed things for me.

This makes the COH 901 318 respect the scatter offset field by using
the sg_phys() rather than the sg_dma_address() so we get a pointer
to the actual data we want to send rather than the beginning of the
buffer. Also initialize the lli:s a bit more thoroughly.

This makes the COH 901 318 configure channel direction (to or from
device) dynamically, instead of being passed in from the platform
data. This was necessary in order to get the MMC/SD-card channel
bidirectional (all other channels on the U300 were either RX or
TX but this one was both). This also sets memcpy() alignent to
even 2^2 (32bit) boundaries, which makes the memcpy() stress tests
start working.

Allocate uninitialized extent before ext4 buffer write and

The purpose is to make sure an extent can only be marked

we can safely drop the i_mutex lock in ext4 DIO read without
