This patch improves support for multiple radio devices.
In previous versions all region relevant settings were derived from one
module parameter. As in future versions, the region and other
configuration should be configurable per device from the user space,
this patch already retrieves all relevant information from the actual
device specific settings.

Looking at these headers as they appear in the kernel makes you
wonder why it is done that way. Refer to the v4l-dvb repository
where the full unstripped header can be found to understand the
reasoning behind this.

This patch:
1) removes the unnecessary kref.h include file
2) removes unnecessary pointer validation from read and poll routines.
(Neither poll nor read may be called unless a call to open succeeds. A
successful call to open will always set the file private_data pointer.
Verifying that it is not null is therefore unnecessary. The associated
release and mmap calls currently ignore this check.)
3) adds a space to syslog output.
4) removes an unused function prototype.

Ian Armstrong pointed out to me that it is perfectly valid to have a
576 lines YUV video with NTSC output in this particular case. In fact,
without this the X driver for ivtv does not function properly.

and add the comments provided by Ian to explain what is happening here.

In v9fs_get_inode(), for block, as well as char devices (in theory),
the function init_special_inode() is called to set up callback functions
for file ops. this function uses the file mode's value to determine whether
to use block or char dev functions. In v9fs_inode_from_fid(), the function
p9mode2unixmode() is used, but for all devices it initially returns S_IFBLK,
then uses v9fs_get_inode() to initialise a new inode, then finally uses
v9fs_stat2inode(), which would determine whether the inode is a block or
character device. However, at that point init_special_inode() had already
decided to use the block device functions, so even if the inode's mode is
turned to a character device, the block functions are still used to operate
on them. The attached patch simply calls init_special_inode() again for devices
after parsing device node data in v9fs_stat2inode() so that the proper functions
are used.

softirq: Add support for triggering softirq work on softirqs.
|

We did not restart the tick device from irq_enter() to avoid double
reprogramming and extra events in the return immediate to idle case.
But long lasting softirqs can lead to a situation where jiffies become
stale:
idle()
tick stopped (reprogrammed to next pending timer)
halt()
interrupt
jiffies updated from irq_enter()
interrupt handler
softirq function 1 runs 20ms
softirq function 2 arms a 10ms timer with a stale jiffies value
jiffies updated from irq_exit()
timer wheel has now an already expired timer
(the one added in function 2)
timer fires and timer softirq runs
This was discovered when debugging a timer problem which happend only
when the ath5k driver is active. The debugging proved that there is a
softirq function running for more than 20ms, which is a bug by itself.
To solve this we restart the tick timer right from irq_enter(), but do
not go through the other functions which are necessary to return from
idle when need_resched() is set.

By the time ide_dma_sgiioc4() gets called, sgiioc4_ide_setup_pci_device() will
have called ioremap() on the whole BAR0 region, so calling ioremap() on the DMA
registers means wasting a page. Replace this call by a mere address calculation,
based on the fact that IRQ registers (pointed to by 'hwif->io_ports.irq_addr')
are situated at offset 0 from BAR0.

The driver performs a number of checks on the virtual/physical addresses which
would always evaluate as true (except ide_dma_sgiioc4() -- always false):
- for sgiioc4_init_hwif_ports(), its caller, sgiioc4_ide_setup_pci_device(),
guarantees that 'ctrl_port' and 'irq_port' parameters are never 0;
- in sgiioc4_read_status(), we always read the IDE status register, so there's
no need to check the register's address (must be a leftover from the times
when this function implemented the INB() method);
- in ide_dma_sgiioc4(), 'dma_base' can never be 0 as IOC4_DMA_OFFSET is not 0.

Since the maskproc() method calls either mirror the interrupt en/disable via

by manipulating the nIEN bit...

Apparently, there is no sense in unmasking IRQ on the controller when you call
disable_irq_nosync() before doing this, set the nIEN bit afterwards, and then
unmask IRQ again after the command completion, hence 0 passed to SELECT_MASK()
before issuing the command in ide_config_drive_speed() is probably just a typo.
