Commit {9a6eb31 ARM: hw_breakpoint: Debug powerdown support for self-hosted debug} introduces debug powerdown support for self-hosted debug. While merging the patch 'has_ossr' check was removed which was needed for hardwares which doesn't support self-hosted debug. Pandaboard (A9) is one such hardware and Dietmar's orginial patch did mention this issue. Without that check on Panda with CPUIDLE enabled, a flood of below messages thrown. [ 3.597930] hw-breakpoint: CPU 0 failed to disable vector catch [ 3.597991] hw-breakpoint: CPU 1 failed to disable vector catch So restore that check back to avoid the mentioned issue.
