From 3b23ed84ec34f04f54f7d5b1e35f258d64a7a5fb Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 30 Jan 2008 13:30:34 +0100 Subject: [PATCH] x86: spinlock_32/64 match the jump labels and symbols Match the jump labels in the 32/64 variants and switch the 64bit version to symbols, so the functions are almost identical except for the operand size now.
