When you have CONFIG_4KSTACKS not set, then compiling mm-sources-2.6.9-rc3-mm2 gives an error at irq.o:
CC arch/i386/kernel/irq.o
arch/i386/kernel/irq.c:203: error: redefinition of `is_irq_stack_ptr'
include/asm/hardirq.h:25: error: `is_irq_stack_ptr' previously defined here
arch/i386/kernel/irq.c: In function `is_irq_stack_ptr':
arch/i386/kernel/irq.c:207: error: `hardirq_stack' undeclared (first use in this function)
arch/i386/kernel/irq.c:207: error: (Each undeclared identifier is reported onlyonce
arch/i386/kernel/irq.c:207: error: for each function it appears in.)
arch/i386/kernel/irq.c:210: error: `softirq_stack' undeclared (first use in this function)
make[1]: *** [arch/i386/kernel/irq.o] Error 1
make: *** [arch/i386/kernel] Error 2
Seems someone in the spanish forum also found the same issue:

Any ideas what causes this and how to fix it? I need to have CONFIG_4KSTACKS not set in order to enable reiser4 support. |
