From c886a9fc1f69c0e53788a9c4a780b6b8825bd4ab Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sun, 29 Apr 2012 03:35:29 -0400 Subject: microblaze: evict the check for kernel_mode(regs) from do_notify_resume() Only one caller hasn't done it in assembler - work_pending on !MMU. Everything else can't reach do_notify_resume() if we are returning to kernel mode, so move that check to that sole caller and make do_notify_resume() reachable only when returning to userland.
