Will Deacon 3a4b5dca53 ARM: 6355/1: hw-breakpoint: add mechanism for hooking into prefetch aborts ... On ARM processors with hardware breakpoint and watchpoint support, triggering these events results in a debug exception. These manifest as prefetch and data aborts respectively. arch/arm/mm/fault.c already provides hook_fault_code for hooking into data aborts dependent on the DFSR. This patch adds a new function, hook_ifault_code for hooking into prefetch aborts in the same manner. Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: S.
