| |
Marcelo,
2.4.19-pre8 gets a linker error if CONFIG_X86_UP_APIC=y and CONFIG_X86_UP_IOAPIC=n:
init/main.o: In function `smp_init': init/main.o(.text.init+0x59e): undefined reference to `skip_ioapic_setup' arch/i386/kernel/kernel.o: In function `broken_pirq': arch/i386/kernel/kernel.o(.text.init+0x3272): undefined reference to `skip_ioapic_setup'
The patch below fixes this. Please apply.
