             Owner: akpm at osdl.org

Problem Description:

  CC      arch/sparc64/kernel/setup.o
In file included from arch/sparc64/kernel/setup.c:32:
include/linux/interrupt.h: In function 'disable_irq_nosync_lockdep':
include/linux/interrupt.h:69: warning: implicit declaration of function
'disable_irq_nosync'
include/linux/interrupt.h: In function 'disable_irq_lockdep':
include/linux/interrupt.h:77: warning: implicit declaration of function
'disable_irq'
include/linux/interrupt.h: In function 'enable_irq_lockdep':
include/linux/interrupt.h:88: warning: implicit declaration of function 'enable_irq'

I inserted
#EXTRA_CFLAGS := -Werror
to work around this.

After commenting out Werror we also have things like:
  CC      kernel/timer.o
In file included from include/asm/irq.h:14,
                 from include/linux/kernel_stat.h:4,
                 from kernel/timer.c:22:

include/linux/interrupt.h: In function 'enable_irq_lockdep':
include/linux/interrupt.h:88: warning: implicit declaration of function 'enable_irq'
In file included from include/linux/kernel_stat.h:4,
                 from kernel/timer.c:22:
include/asm/irq.h: At top level:
include/asm/irq.h:112: warning: conflicting types for 'disable_irq'
include/linux/interrupt.h:77: warning: previous implicit declaration of
'disable_irq' was here
include/asm/irq.h:114: warning: conflicting types for 'enable_irq'
include/linux/interrupt.h:88: warning: previous implicit declaration of
'enable_irq' was here


this is what we end up with finally:

  CC      mm/fremap.o
mm/fremap.c: In function 'install_page':
include/asm/pgtable.h:236: error: invalid 'asm': operand number missing after
%-letter

make[1]: *** [mm] Error 2
make[1]: Leaving directory `/usr/src/linux-2.6.17-rc5-mm2'
make: *** [debian/stamp-build-kernel] Error 2
