This patch adds kernel doc for the completion feature. It is in kernel/sched.c
and include/linux/completion.h.
An error in the split-man.pl PERL snippet in kernel-doc-nano-HOWTO.txt is
also fixed.

Thanks for posting this driver and for your attention for detail
and for documentation in particular. Few people bother to write
documentation at this level.

Hi,
When I tried building my cpufreq driver into the kernel, the
cpufreq stats driver quit working? Anyone know if I screwed something up?
Or is this normal (2.6.26)?
Also, I thought, apparently incorrectly, That module parameters
became boot parameters when the module was built

Can I ignore these checkpatch errors:

Hi,
I am trying to do some compile testing of my cpufreq driver. If
I disable modules I am getting multiple definition errors of inline
functions:

unsigned int ret;
__asm__ __volatile__ (mfspr %0,%1:

Could I get any needed corrections on this. Especially on the ???

Hi,
Something in a function signature called __attribute_used__ would
compile in 2.6.24. This does not compile in 2.6.26. Using the
store_##NAME template from arch/powerpc/kernel/sysfs.c as a guide,
this appears to have changed to __used. Anything work in both?
__used seems to have compiled

In the 750GX data sheet (750GX_ds2-17-05.pdf), page 45 has Table 5-1

PLL_RNGrange

01900 - 1000
10500 - 600
Anyone have any thoughts as to what the correct
