[PATCH] i386: clean up vDSO alignment padding

From: Roland McGrath
Date: Thu Jul 28 2005 - 03:28:28 EST

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.
