From 73bf463efaba6a1efe69349c6d7275d03468adf4 Mon Sep 17 00:00:00 2001 From: Michael Holzheu Date: Thu, 24 May 2012 14:35:16 +0200 Subject: s390/kernel: Introduce memcpy_absolute() function This patch introduces the new function memcpy_absolute() that allows to copy memory using absolute addressing. This means that the prefix swap does not apply when this function is used. With this patch also all s390 kernel code that accesses absolute zero now uses the new memcpy_absolute() function. The old and less generic copy_to_absolute_zero() function is removed.
