From e0877f07e85a46e4fde32bd84f08551d360839fe Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Sat, 25 Jun 2005 14:55:21 -0700 Subject: [PATCH] uml: fork cleanup Fix the do_fork calling convention: normal arch pass the regs and the new sp value to do_fork instead of NULL. Currently the arch-independent code ignores these values, while the UML code (actually it's copy_thread) gets the right values by itself. With this patch, things are fixed up.
