From 3a24ebf0cb2ca44fdcdb5cae9ed2e778e5170f97 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Mon, 4 Feb 2008 22:31:16 -0800 Subject: uml: remove init_irq_signals init_irq_signals doesn't need to be called from the context of a new process. It initializes handlers, which are useless in process context. With that call gone, init_irq_signals has only one caller, so it can be inlined into init_new_thread_signals.
