*netif_rx_* functions is obsolete and removed in newer kernels so
we need to use corresponding *napi_* functions instead.

Driver for Dave DNET ethernet controller found on Dave/DENX QongEVB-LITE

Impact: help prevent extinction of species
The Tasmanian Devil is a shy iconic Australian creature named for its
spine-chilling screech. It is threatened with extinction due to a
scientifically interesting but horrific transmissible facial cancer.
This one is standing in for Tux for one release using the far less-known
Devil Facial Tux Disguise.

filp->f_pos only get updated at the end of the function. Thus d_off of those
dirents who are in the middle will be 0, and this will cause a problem in
glibc's readdir implementation, specifically endless loop. Because when overflow
occurs, f_pos will be set to next dirent to read, however it will be 0, unless
the next one is the last one. So it will start over again and again.
There is a sample program in man 2 gendents. This is the output of the program
running on a multithread program's task dir before this patch is applied:
$ ./a.out /proc/3807/task

Impact: fix for losing comms in trace
The command lines of tasks are cached at sched switch to not need
to record them at every trace point. Disabling the tracing on stops
the recording of traces, but does not stop the caching of command lines.
When the tracing is off the cache may overflow and cause the tracing
to show incorrect tasks matching the PIDs.
This patch disables prevents updates to the comm cache when the ring buffer
is off.

Impact: fix to one cause of incorrect comm outputs in trace
The spinlock only protected the creation of a comm <=> pid pair.
But it was possible that a reader could look up a pid, and get the
wrong comm because it had no locking.
This also required changing trace_find_cmdline to copy the comm cache
and not just send back a pointer to it.

Impact: fix a dynamic tracing failure
Recently, the function and function graph tracers failed to use dynamic
tracing after the following commit:
fa9d13cf135efbd454453a53b6299976bea245a9
(ftrace: don't try to __ftrace_replace_code on !FTRACE_FL_CONVERTED rec)
The patch is right except a mistake on the check for the FTRACE_FL_CONVERTED
flag. The code patching is aborted in case of successfully nopped sites.
What we want is the opposite: ignore the callsites that haven't been nopped.

[ 6.060000] [<ffffffff8102510b>] init_irqsoff_tracer+0x3b/0x53
This is because in fail case, the preemptirqsoff tracer selftest calls twice
the tracing_start() function:
int
trace_selftest_startup_preemptirqsoff(struct tracer *trace, struct trace_array *tr)
{
if (!ret && !count) {
printk(KERN_CONT ".. no entries found ..");
ret = -1;
tracing_start(); <-----
goto out;
}
[...]
out:
trace->reset(tr);
tracing_start(); <------
tracing_max_latency = save_max;
return ret;
}
Since it is well handled in the out path, we don't need the conditional one.

Syscall tracing must select kallsysms.
The arch code builds a table to find the syscall metadata by syscall
number. It needs the syscalls names resolution from the symbol table
to know which name found on the syscalls metadatas match a function
pointer from the arch sys_call_table.

Impact: fix syscall tracer enable/disable race
The current thread flag toggling is racy as shown in the following
scenario:
- task A is the last user of syscall tracing, it releases the
TIF_SYSCALL_FTRACE on each tasks
- at the same time task B start syscall tracing. refcount == 0 so
it sets up TIF_SYSCALL_FTRACE on each tasks.
The effect of the mixup is unpredictable.
So this fix adds a mutex on {start,stop}_syscall_tracing().

Impact: fix 'stuck' syscall tracer
The syscall tracer uses a refcounter to enable several users
simultaneously.
But the refcounter did not behave correctly and always restored
its value to 0 after calling start_syscall_tracing(). Therefore,
stop_syscall_tracing() couldn't release correctly the tasks from
tracing.
Also the tracer forgot to reset the buffer when it is released.
Drop the pointless refcount decrement on start_syscall_tracing()
and reset the buffer when we release the tracer.
This fixes two reported issue:
- when we switch from syscall tracer to another tracer, syscall
tracing continued.
- incorrect use of the refcount.

The current use of these macros works well when the conversion is
entirely linear. In this case, we can be assured that the following
holds true:
__va(p + s) - s = __va(p)
However, this is not always the case, especially when there is a
non-linear conversion (eg, when there is a 3.5GB hole in memory.)
In this case, if 's' is the size of the region (eg, PAGE_SIZE) and
'p' is the final page, the above is most definitely not true.
So, we must ensure that __va() and __pa() are only used with valid
kernel direct mapped RAM addresses. This patch tweaks the code
to achieve this.

This is a fix for the following crash observed in 2.6.29-rc3:
http://lkml.org/lkml/2009/1/29/150
On ARM it doesn't make sense to trace a naked function because then
mcount is called without stack and frame pointer being set up and there
is no chance to restore the lr register to the value before mcount was
called.

Changing it do 100kHz is needed to make more devices works properly. Controlling the
TI DLP Pico projector[1] doesn't work properly at 400kHz, 100kHz and lower work fine.
EDID readout is unaffected by this change.

After my OMAP3 board has been running for a while, I'm seeing weird
latency traces like this:
sh-1574 0d.h2 153us : do_timer (tick_do_update_jiffies64)
sh-1574 0d.h2 153us : update_wall_time (do_timer)
sh-1574 0d.h2 153us!: omap_32k_read (update_wall_time)
sh-1574 0d.h2 1883us : update_xtime_cache (update_wall_time)
sh-1574 0d.h2 1883us : clocksource_get_next (update_wall_time)
sh-1574 0d.h2 1883us+: _spin_lock_irqsave (clocksource_get_next)
and after a while:
sh-17818 0d.h3 153us : do_timer (tick_do_update_jiffies64)
sh-17818 0d.h3 153us : update_wall_time (do_timer)
sh-17818 0d.h3 153us!: omap_32k_read (update_wall_time)
sh-17818 0d.h3 1915us : update_xtime_cache (update_wall_time)
sh-17818 0d.h3 1915us+: clocksource_get_next (update_wall_time)
sh-17818 0d.h3 1945us : _spin_lock_irqsave (clocksource_get_next)
Turns out that sched_clock() is using cyc2ns(), which returns NTP
adjusted time. The sched_clock() frequency should not be adjusted. The
patch deletes omap_32k_ticks_to_nsecs() and rewrites sched_clock()
to do the conversion using the constant multiplier.

Some of the rate selection logic in s3c64xx_setrate_clksrc uses what
appears to be parent clock selection logic. This patch corrects it.
I also added a check for overly large dividers to prevent them from
changing unrelated clocks.

arch_initcall() runs after the machine init function which means that
any configuration of GPIO pins must currently be done later on, for
example in callbacks from drivers. Move the initialisation earlier in
order to allow machines to configure GPIOs directly in their init
functions rather than having to have a callback invoked later on.
Some other ARM platforms use this method. Other solutions for this
include providing a special interface for setting up GPIOs en masse,
adding callbacks to do the GPIO configuration from devices and doing
the GPIO configuration implicitly.
