From Bugzilla Helper: User-Agent: Mozilla/5.0 (compatible; Konqueror/3.3; Linux) (KHTML, like Gecko) Description of problem: When I manually configure the kernel for my personal setup using the kernel source package with the 8K kernel stack option, I get link errors saying that it cannot find irq_ctx_init(). I have traced this to some weird #ifdef/#ifndef CONFIG_XEN statements in include/asm-i386/irq.h. The #ifdefs may help in compiling the XEN kernels, but if you configure 8K stacks you can't link normal kernels. The patch introducing the change is called: linux-2.6.9-xen-compile.patch Version-Release number of selected component (if applicable): kernel-2.6.11-1.1170_FC4 How reproducible: Always Steps to Reproduce: 1. Configure 8K stack with menu config or any config tool 2. Build kernel 3. Actual Results: Link failure on missing symbol: irq_ctx_init Expected Results: Linked linux kernel Additional info: After reverting the part of the patch below, the kernel compiles and links fine. --- linux-2.6.9/include/asm-i386/irq.h~ 2004-12-24 01:46:10.908739264 -0500 +++ linux-2.6.9/include/asm-i386/irq.h 2004-12-24 01:48:25.183326424 -0500 @@ -28,10 +28,14 @@ extern void release_vm86_irqs(struct tas #endif #ifdef CONFIG_4KSTACKS + #ifndef CONFIG_XEN extern void irq_ctx_init(int cpu); # define __ARCH_HAS_DO_SOFTIRQ + #endif #else + #ifdef CONFIG_XEN # define irq_ctx_init(cpu) do { } while (0) + #endif #endif #ifdef CONFIG_IRQBALANCE
