From 16a8016372c42c7628eb4a39d75386a461e8c5d0 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Fri, 1 Jun 2012 14:22:01 -0400 Subject: sanitize tsk_is_polling() Make default just return 0. The current default (checking TIF_POLLING_NRFLAG) is taken to architectures that need it; ones that don't do polling in their idle threads don't need to defined TIF_POLLING_NRFLAG at all. ia64 defined both TS_POLLING (used by its tsk_is_polling()) and TIF_POLLING_NRFLAG (not used at all). Killed the latter...
