For some reasons, I have to compile kernel 2.6.4 on my computer.
My existing system is: Opensuse 10.2 on VMware station 6.5.1 kernel gcc 3.4.2

My procedures are:
make mrproper
make menuconfig
make dep
make bzImage
Then I have the problem is:
arch/i386/mach-generic/summit.c: In function `send_IPI_all':
include/asm/mach-summit/mach_ipi.h:4: sorry, unimplemented: inlining failed in call to 'send_IPI_mask_sequence': function body not available
arch/i386/mach-generic/summit.c:8: sorry, unimplemented: called from here
make[1]: *** [arch/i386/mach-generic/summit.o] Error 1
make: *** [arch/i386/mach-generic] Error 2

Thanks in advance
