[PATCH] Make second arg to skb_reserved() signed.
Some subsystems, such as PPP, can send negative values here. It just happened to work correctly on 32-bit with an unsigned value, but on 64-bit this explodes. Figured out by Paul Mackerras based upon several PPP crash reports. Signed-off-by: David S.
