thanks, applied. The effect of this bug is that block-stepping is not disabled ... [~TIF_DEBUGCTLMSR masks out bit 25, while in the MSR we want to mask out bit 1]
Roland - i guess this means block-stepping (a new ptrace feature in .25) is not particularly well-tested. Do you have any standalone testcases that could be run?
