From f80dff9da07d81da16e3b842118d47b9febf9c01 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Fri, 16 Feb 2007 22:16:32 +0100 Subject: [ARM] 4185/2: entry: introduce get_irqnr_preamble and arch_ret_to_user get_irqnr_preamble allows machines to take some action before entering the get_irqnr_and_base loop. On iop we enable cp6 access. arch_ret_to_user is added to the userspace return path to allow individual architectures to take actions, like disabling coprocessor access, before the final return to userspace. Per Nicolas Pitre's note, there is no need to cp_wait on the return to user as the latency to return is sufficient.
