docs: move remaining stuff under Documentation/*.txt to Documentation/staging

2020-06-19T20:17:05+00:00

There are several files that I was unable to find a proper place for them, and 3 ones that are still in plain old text format. Let's place those stuff behind the carpet, as we'd like to keep the root directory clean. We can later discuss and move those into better places.

kprobes/x86: Do not disable preempt on int3 path

2018-06-21T10:33:20+00:00

Since int3 and debug exception(for singlestep) are run with IRQ disabled and while running single stepping we drop IF from regs->flags, that path must not be preemptible. So we can remove the preempt disable/enable calls from that path.

kprobes: Don't check the ->break_handler() in generic kprobes code

2018-06-21T10:33:12+00:00

Don't check the ->break_handler() from the core kprobes code, because it was only used by jprobes which got removed. ( In followup patches we'll remove the remaining calls in low level arch handlers as well and remove the callback altogether. ) Signed-off-by: Masami Hiramatsu Acked-by: Thomas Gleixner Cc: Ananth N Mavinakayanahalli Cc: Andrew Morton Cc: Linus Torvalds Cc: Peter Zijlstra Cc: Steven Rostedt Cc: linux-arch@vger.kernel.org Link: https://lore.kernel.org/lkml/152942462686.15209.6324404940493598980.stgit@devbox Signed-off-by: Ingo Molnar
