[PATCH v11 1/7] ARM: probes: move all probe code to dedicate directory

Mon Dec 1 00:48:15 PST 2014


In discussion on LKML (https://lkml.org/lkml/2014/11/28/158), Russell
King suggest to move all probe related code to arch/arm/probes. This
patch do the work. Due to dependency on 'arch/arm/kernel/patch.h', this
patch also move patch.h to 'arch/arm/include/asm/patch.h', and related
'#include' directive are also midified to '#include <asm/patch.h>'.
