It seems commit32ee8c3e47accidentially revertedcdc9cc1d74, IOW, it reintroduced the following compile error with CONFIG_PCI=n: <-- snip --> ... CC arch/i386/kernel/cpu/cpufreq/gx-suspmod.o arch/i386/kernel/cpu/cpufreq/gx-suspmod.c: In function ‘gx_detect_chipset’: arch/i386/kernel/cpu/cpufreq/gx-suspmod.c:193: error: implicit declaration of function ‘pci_match_id’ arch/i386/kernel/cpu/cpufreq/gx-suspmod.c:193: warning: comparison between pointer and integer make[3]: *** [arch/i386/kernel/cpu/cpufreq/gx-suspmod.o] Error 1 <-- snip --> This patch therefore re-adds the dependency of X86_GX_SUSPMOD on PCI.
