From: Heiko Carstens Date: Wed, 12 Jul 2006 14:39:47 +0000 (+0200) Subject: [S390] raw_local_save_flags/raw_local_irq_restore type check X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=63f4f9e1281ea9b9a2304bd13d657ba9d401c9a7;p=openwrt%2Fstaging%2Fblogic.git [S390] raw_local_save_flags/raw_local_irq_restore type check Make sure that raw_local_save_flags and raw_local_irq_restore always get an unsigned long parameter. raw_irqs_disabled should call raw_local_save_flags instead of local_save_flags.
