genirq, ARM: Fix boot on ARM platforms Commit b683de2b3 in linux-next as of 20101014 (genirq: Query arch for number of early descriptors) seems to have broken bootup on several ARM boards - my beagleboard gives the following dump with earlyprintk: NR_IRQS:402 Unable to handle kernel NULL pointer dereference at virtual address 00000028 pgd = c0004000 [00000028] *pgd=00000000 Internal error: Oops: 5 [#1] last sysfs file: Modules linked in: CPU: 0 Not tainted (2.6.36-rc7-next-20101014-linux-next-20101012+ #40) PC is at init_IRQ+0x14/0x48 LR is at start_kernel+0x150/0x2c0 [...] We seem to be using desc->status without assigning desc to anything. Fix this by adding back the code that was originally there.
