[PATCH] mips: qemu network work again
After kernel 2.6.21, the qemu of mips with nfsroot is not working.
There are too much WATCHDOG timeout.
I try to find what makes it not working and I found it.
After Ingo Monlar's patch "[PATCH] genirq: do not mask interrupts by default"
[1], it's not working.
To solve this, we also have to register the IRQ disable field in MIPS, as x86
does.
