p4-clockmod does not compile under 2.6.1-mm3

Hello :-)

bash-2.05b# gcc --version
gcc (GCC) 3.2.3

bash-2.05b# make
  SPLIT   include/linux/autoconf.h -> include/config/*
make[1]: `arch/i386/kernel/asm-offsets.s' is up to date.
  CHK     include/linux/compile.h
  CC      arch/i386/kernel/cpu/cpufreq/p4-clockmod.o
arch/i386/kernel/cpu/cpufreq/p4-clockmod.c: In function `cpufreq_p4_setdc':
arch/i386/kernel/cpu/cpufreq/p4-clockmod.c:71: `cpu_sibling_map' undeclared 
(first use in this function)
arch/i386/kernel/cpu/cpufreq/p4-clockmod.c:71: (Each undeclared identifier 
is reported only once
arch/i386/kernel/cpu/cpufreq/p4-clockmod.c:71: for each function it appears 
in.)
make[3]: *** [arch/i386/kernel/cpu/cpufreq/p4-clockmod.o] Error 1
make[2]: *** [arch/i386/kernel/cpu/cpufreq] Error 2
make[1]: *** [arch/i386/kernel/cpu] Error 2
make: *** [arch/i386/kernel] Error 2

adding a cpumask_t cpu_sibling_map[NR_CPUS] to the function make it compile 
but i think this is a very bad solution (sorry I'm not a kernel hacker :-)


Thanks,
Eduard

thanks for your report.

This was a known bug in -mm3 that is already fixed in -mm4 [1].

You should enable 

 Pentium-4/Celeron(P4-based)/Pentium-4 M/Xeon

under   Processor type and features --> Processor support.
