From: Ananth N Mavinakayanahalli <ana...@in.ibm.com> The current implementation of uprobes assumes that uprobes always wins even when a register request is at a location with a conditional breakpoint by some other entity. Refer to [1] for more details.
Remove the breakpoint instruction check during registration on powerpc, so that uprobes behavior on powerpc matches that of x86.
