From 2a0694d15d55d0deed928786a6393d5e45e37d76 Mon Sep 17 00:00:00 2001 From: Roland McGrath <roland@redhat.com> Date: Sat, 3 Sep 2005 15:56:35 -0700 Subject: [PATCH] [PATCH] i386: clean up vDSO alignment padding This makes the vDSO use nops for all its padding around instructions, rather than sometimes zeros, and nop-pads the end of the area containing instructions to a 32-byte cache line, to keep text and data in separate lines.
