irq: Add disabling counter
* linux/dev/arch/i386/kernel/irq.c (ndisabled_irq): New array.
(__disable_irq, __enable_irq): New functions, count with ndisabled_irq
before really calling mask_irq/unmask_irq.
(linux_pic_mask): New variable.
(disable_irq, enable_irq): Manage linux_pic_mask and call
__disable_irq/__enable_irq instead of calling mask_irq/unmask_irq.
* linux/src/include/asm-i386/irq.h (__disable_irq, __enable_irq): New
prototypes.
