From e1a79c400a86f2f6a6735480e31f6ee159e76fa2 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Thu, 10 May 2007 22:22:31 -0700 Subject: [PATCH] uml: use UM_THREAD_SIZE in userspace code Now that we have UM_THREAD_SIZE, we can replace the calculations in user-space code (an earlier patch took care of the kernel side of the house).
