[patch] arch/mips/au1000/common/time.c

["Joseph Chiu" <joseph@omnilux.net>]

Hi,

I reported on this a few years ago on 2.4.18, but it never seemed to have been 
addressed...

in linux/arch/mips/au1000/common/time.c, mips_timer_interrupt calls irq_enter() 
*before*
checking if (r4k_offset == 0), and then exits the interrupt without calling 
irq_exit().

This problem was crashing our boards in some test cases...  Please apply.

Thanks,
Joseph
