This -v6 revision incorporates the feedbacks of -v5 revision from Frederic
Weisbecker, the most important changes include:

1. tracing: add IRQENTRY_EXIT section for MIPS

Tag the mips irq entry functions with "__irq_entry".

2. "notrace" relative patches

To avoid hanging on mips_timecounter_read() when using function graph tracer,
we need not to trace the subroutines called by mips_timecounter_read(). for the
mips specific subroutines, we use __notrac_funcgraph to tag them.

For the common timecounter_read_* functions, we add a new __arch_notrace
flag/macro to include/linux/ftrace.h for the arch specific requirement, and use
it to tag them. and then we define the macro in arch/mips/include/asm/ftrace.h
to make it take effect for MIPS.

All of the latest update have been pushed into:

git://dev.lemote.com/rt4ls.git linux-mips/dev/ftrace-upstream

Thanks & Regards,
Wu Zhangjin
