From 2c332a251302873cf8301c2aad27737b6df70255 Mon Sep 17 00:00:00 2001 From: Bodo Stroesser Date: Wed, 18 Jan 2006 17:42:43 -0800 Subject: [PATCH] [PATCH] uml: change interface to boot_timer_handler Current implementation of boot_timer_handler isn't usable for s390. So I changed its name to do_boot_timer_handler, taking (struct sigcontext *)sc as argument. do_boot_timer_handler is called from new boot_timer_handler() in arch/um/os-Linux/signal.c, which uses the same mechanisms as other signal handler to find out sigcontext pointer.
