2.6.7-mm2 build errors...

LD .tmp_vmlinux1
arch/i386/kernel/built-in.o(.text+0xbe14): In function `powernow_acpi_init':
: undefined reference to acpi_processor_register_performance' arch/i386/kernel/built-in.o(.text+0xbe3b): In function powernow_acpi_init':

: undefined reference to `acpi_processor_unregister_performance'
make: *** [.tmp_vmlinux1] Error 1

This also happens in 2.6.7-mm1, I'm wondering if this is my fault or something's wrong?

Thanks in advance!
JC

PS: Please CC me for any answer.

It seems something is/was wrong.

Can you still reproduce it in 2.6.7-mm5?
If yes, please send your .config.

        of the darkness. There had been need of rain for many days.
       "Only a promise," Lao Er said.

Same as this problem report:
http://marc.theaimsgroup.com/?l=linux-kernel&m=108752330915120&w=2

but my patch was insufficient:
http://marc.theaimsgroup.com/?l=linux-kernel&m=108753512102539&w=2

See reply from Dave Jones. And I see what he means, but I don't see how to express it in Kconfig language.

What about the patch below?

Fix compile errors with X86_POWERNOW_K{7,8}=y and ACPI_PROCESSOR=m.

Looks good, I'll give it a test later, and roll it into cpufreq-bk and let it simmer in -mm for a few days. (There's a bunch of other cpufreq bits that have backlogged which I also need to get some testing of).
