Subject: [PATCH -next] powernow-k8: fix build errors

From: Randy Dunlap <[email protected]>

Fix build when CONFIG_X86_POWERNOW_K8_ACPI=n:
(seems that someone forgot to test this build combo)
(fix 25 of 50 randconfig build errors)

linux-next-20080808/arch/x86/kernel/cpu/cpufreq/powernow-k8.c:1334: error: implicit declaration of function 'powernow_k8_cpu_preinit_acpi'
linux-next-20080808/arch/x86/kernel/cpu/cpufreq/powernow-k8.c:1352: error: 'acpi_perf_data' undeclared (first use in this function)

Yikes. I'll add that to my pre-push test script.
(I currently only test allmodconfig/allyes/allno for all
