Revision 928923c76b393e38e5ba1d47e843e208ceef6cf9 authored by Geert Uytterhoeven on 22 August 2007, 21:01:36 UTC, committed by Linus Torvalds on 23 August 2007, 02:52:45 UTC 
Introduce CONFIG_CHECK_SIGNATURE
 
Introduce CONFIG_CHECK_SIGNATURE to control inclusion of check_signature()
and avoid problems on platforms that don't have readb().

Let the few legacy (ISA || PCI || X86) drivers that need check_signature()
select CONFIG_CHECK_SIGNATURE.
