Will Deacon 6f26aa05c9 ARM: hw_breakpoint: add support for multiple watchpoints ... ARM debug architecture 7.1 mandates that the DFAR is updated on a watchpoint debug exception to contain the faulting virtual address of the memory access. This allows us to determine which watchpoints have fired and therefore report useful information to userspace. This patch adds support for using the DFAR in the watchpoint handler, which allows us to support multiple watchpoints on CPUs implementing the new debug architecture.
