-stable review patch. If anyone has any objections, please let us know. ------------------ From: Francois Romieu Theory : though needless, it should not have hurt. Practice: it does not play nice with DEBUG_SHIRQ + LOCKDEP + UP (see https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=3D242572). The patch makes sense in itself but I should dig why it has an effect on #242572 (assuming that NAPI do not change in a near future). Patch in mainline as 313b0305b5a1e7e0fb39383befbf79558ce68a9c. Backported to 2.6.22-stable by Thomas M=FCller.
