Компиляция ядра

Имею RH 7 (или он меня). Как только выключаю smp support, ядро перестает компилиться и в конце говорит вот это: /usr/src/linux-2.2.16/include/asm/hardirq.h:23:24: warning: "synchronize_irq" redefined /usr/src/linux-2.2.16/include/linux/modules/i386_ksyms.ver:138:1: warning: this is the location of the previous definition In file included from ksyms.c:18: /usr/src/linux-2.2.16/include/linux/kernel_stat.h: In function `kstat_irqs': /usr/src/linux-2.2.16/include/linux/kernel_stat.h:47: `smp_num_cpus' undeclared(first use in this function) /usr/src/linux-2.2.16/include/linux/kernel_stat.h:47: (Each undeclared identifier is reported only once /usr/src/linux-2.2.16/include/linux/kernel_stat.h:47: for each function it appears in.)
