sparc64: Fix stack debugging IRQ stack regression.
Commit 4f70f7a91bffdcc39f088748dc678953eb9a3fbd (sparc64: Implement IRQ stacks.) has two bugs. First, the softirq range check forgets to subtract STACK_BIAS before comparing with %sp. Next, on failure the wrong label is jumped to, resulting in a bogus stack being loaded. Reported-by: Igor Kovalenko <igor.v.kovalenko@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
