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.

This is primarily a cosmetic change to make it easier to change some

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
