Only one frontend is enabled right now. The second frontend can lock,
but transport doesn't work yet. The device will be supported as a
single tuner device until the second frontend is working.

The naming for the callbacks that handle the VIDIOC_ENUM_FMT and
VIDIOC_S/G/TRY_FMT ioctls was very confusing. Renamed it to match

There was no vidioc_try_fmt_sliced_vbi_output, instead vidioc_try_fmt_vbi_output

The VIDIOC_ENUMOUTPUT handling was missing altogether, even though the callback

Back in the early days of the pvrusb2 driver, the kernel class
mechanism in use for the sysfs interface had no means to pass
per-attribute information to the show / store functions. This forced
me to implement a horrible ugly thunking mechanism (i.e. infer the
missing data through the use of dedicated cookie cutter bounce
functions). However now we're using a better mechanism which also
passes enough additional information to the show / store functions
that we no longer need the hack. So eliminate all the crap. Yay!

The driver enforces a "quiet period" on the encoder in certain
situations before attempting to operate it. This seems to help avoid
video encoding errors / corruption. The quiet period was 50msec, but
through experimentation it has been observed to improve further if the
interval is increased to 100msec.

write() operations to the ivtv framebuffer will now attempt to use DMA if the
amount of data to copy is >= 4096 bytes. This change effectively depreciates
the need for the proprietary IVTVFB_IOC_DMA_FRAME ioctl since a write() of
sufficient size will do the same thing.

The pvrusb2 driver initially sets the tuner to known broadcast frequencies
in the Chicago area, to ease driver testing for the maintainer.
This patch keeps those default frequencies, but allows them to be altered
via modprobe option. This allows the same ease and convenience for testing
multiple pvrusb2 devices one after another under other conditions and areas.
For instance, the default initial frequency, 175.25 MHz, might not
necessarily be valid on all cable television networks, but usually will be a
valid NTSC broadcast channel.

make function tracing more robust: do not trace library functions.
We've already got a sizable list of exceptions:
ifdef CONFIG_FTRACE
# Do not profile string.o, since it may be used in early boot or vdso
CFLAGS_REMOVE_string.o = -pg
# Also do not profile any debug utilities
CFLAGS_REMOVE_spinlock_debug.o = -pg
CFLAGS_REMOVE_list_debug.o = -pg
CFLAGS_REMOVE_debugobjects.o = -pg
CFLAGS_REMOVE_find_next_bit.o = -pg
CFLAGS_REMOVE_cpumask.o = -pg
CFLAGS_REMOVE_bitmap.o = -pg
endif
... and the pattern has been that random library functionality showed
up in ftrace's critical path (outside of its recursion check), causing
hard to debug lockups.
So be a bit defensive about it and exclude all lib/*.o functions by
default. It's not that they are overly interesting for tracing purposes
anyway. Specific ones can still be traced, in an opt-in manner.

MAXSMP brings in lots of use of various bitops in smp_processor_id()
and friends - causing ftrace to lock up during bootup:
calling anon_inode_init+0x0/0x130
initcall anon_inode_init+0x0/0x130 returned 0 after 0 msecs
calling acpi_event_init+0x0/0x57
[ hard hang ]
So exclude the bitops facilities from tracing.
