linux-toradex.git/arch/powerpc/kernel/suspend.c, branch v2.6.25.12 Linux kernel for Apalis and Colibri modules [PATCH] x86: Move swsusp __pa() dependent code to arch portion 2007-05-02T17:27:07+00:00 Vivek Goyal vgoyal@in.ibm.com 2007-05-02T17:27:07+00:00 49c3df6aaa6a51071fc135273d1a2515d019099f o __pa() should be used only on kernel linearly mapped virtual addresses and not on kernel text and data addresses. o Hibernation code needs to determine the physical address associated with kernel symbol to mark a section boundary which contains pages which don't have to be saved and restored during hibernate/resume operation. o Move this piece of code in arch dependent section. So that architectures which don't have kernel text/data mapped into kernel linearly mapped region can come up with their own ways of determining physical addresses associated with a kernel text.

o __pa() should be used only on kernel linearly mapped virtual addresses
  and not on kernel text and data addresses.

o Hibernation code needs to determine the physical address associated
  with kernel symbol to mark a section boundary which contains pages which
  don't have to be saved and restored during hibernate/resume operation.

o Move this piece of code in arch dependent section. So that architectures
  which don't have kernel text/data mapped into kernel linearly mapped
  region can come up with their own ways of determining physical addresses
  associated with a kernel text.
