      x86/idt: Remove X86_TRAP_BP initialization in idt_setup_traps() · d0cd64b0
      Yonghong Song authored
      Commit b70543a0("x86/idt: Move regular trap init to tables") moves
      regular trap init for each trap vector into a table based
      initialization. It introduced the initialization for vector X86_TRAP_BP
      which was not in the code which it replaced. This breaks uprobe
      functionality for x86_32; the probed program segfaults instead of handling
      the probe proper.
      The reason for this is that TRAP_BP is set up as system interrupt gate
      (DPL3) in the early IDT and then replaced by a regular interrupt gate
      (DPL0) in idt_setup_traps(). The DPL0 restriction causes the int3 trap
      to fail with a #GP resulting in a SIGSEGV of the probed program.
      On 64bit this does not cause a problem because the IDT entry is replaced
      with a system interrupt gate (DPL3) with interrupt stack afterwards.
      Remove X86_TRAP_BP from the def_idts table which is used in
      idt_setup_traps(). Remove a redundant entry for X86_TRAP_NMI in def_idts
      while at it. Tested on both x86_64 and x86_32.

      x86/unwind: Disable KASAN checking in the ORC unwinder · 881125bf
      Josh Poimboeuf authored
      Fengguang reported a KASAN warning:
        Kprobe smoke test: started

        Call Trace:
      The ORC unwinder got confused by some kprobes changes, which isn't
      surprising since the runtime code no longer matches vmlinux and the
      stack was modified for kretprobes.
      Until we have a way for generated code to register changes with the
      unwinder, these types of warnings are inevitable.  So just disable KASAN
      checks for stack accesses in the ORC unwinder.

      objtool: Prevent GCC from merging annotate_unreachable(), take 2 · ec1e1b61
      Josh Poimboeuf authored
      This fixes the following warning with GCC 4.6:
        mm/migrate.o: warning: objtool: migrate_misplaced_transhuge_page()+0x71: unreachable instruction
      The problem is that the compiler merged identical annotate_unreachable()
      inline asm blocks, resulting in a missing 'unreachable' annotation.
      This problem happened before, and was partially fixed with:
       ("objtool: Prevent GCC from merging annotate_unreachable()")
      That commit tried to ensure that each instance of the
      annotate_unreachable() inline asm statement has a unique label.  It used
      the __LINE__ macro to generate the label number.  However, even the line
      number isn't necessarily unique when used in an inline function with
      multiple callers (in this case, __alloc_pages_node()'s use of

      Revert "x86/mm: Stop calling leave_mm() in idle code" · 67535736
      Andy Lutomirski authored
      This reverts commit 43858b4f.
      The reason I removed the leave_mm() calls in question is because the
      heuristic wasn't needed after that patch.  With the original version
      of my PCID series, we never flushed a "lazy cpu" (i.e. a CPU running
      kernel thread) due a flush on the loaded mm.
      Unfortunately, that caused architectural issues, so now I've
      reinstated these flushes on non-PCID systems in:
          commit b956575b
       ("x86/mm: Flush more aggressively in lazy TLB mode").
      That, in turn, gives us a power management and occasionally
      performance regression as compared to old kernels: a process that
      goes into a deep idle state on a given CPU and gets its mm flushed
      due to activity on a different CPU will wake the idle CPU.
      Reinstate the old ugly heuristic: if a CPU goes into ACPI C3 or an
      intel_idle state that is likely to cause a TLB flush gets its mm
      switched to init_mm before going idle.
      FWIW, this heuristic is lousy.  Whether we should change CR3 before
      idle isn't a good hint except insofar as the performance hit is a bit
      lower if the TLB is getting flushed by the idle code anyway.  What we
      really want to know is whether we anticipate being idle long enough
      that the mm is likely to be flushed before we wake up.  This is more a
      matter of the expected latency than the idle state that gets chosen.
      This heuristic also completely fails on systems that don't know
      whether the TLB will be flushed (e.g. AMD systems?).  OTOH it may be a
      bit obsolete anyway -- PCID systems don't presently benefit from this
      heuristic at all.
      We also shouldn't do this callback from innermost bit of the idle code
      due to the RCU nastiness it causes.  All the information need is
      available before rcu_idle_enter() needs to happen.

      tools/headers: Synchronize kernel ABI headers · fb7df12d
      Ingo Molnar authored
      After the SPDX license tags were added a number of tooling headers got out of
      sync with their kernel variants, generating lots of build warnings.
      Sync them:
       - tools/arch/x86/include/asm/disabled-features.h,
           Remove the SPDX tag where the kernel version does not have it.
       - tools/include/asm-generic/bitops/__fls.h,
           Add the SPDX tag of the respective kernel header.
       - tools/include/uapi/linux/bpf_common.h,
           Change the tag to the kernel header version:
             -/* SPDX-License-Identifier: GPL-2.0 */
             +/* SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note */
      Also sync other header details:
       - include/uapi/sound/asound.h:
           Fix pointless end of line whitespace noise the header grew in this cycle.
       - tools/arch/x86/lib/memcpy_64.S:
           Sync the code and add tools/include/asm/export.h with dummy wrappers
           to support building the kernel side code in a tooling header environment.
       - tools/include/uapi/asm-generic/mman.h,
           Sync other details that don't impact tooling's use of the ABIs.

      Stefan Brüns authored
      Sync events are sent by sparse_keymap_report_entry for normal KEY_*
      events, and are generated by several drivers after generating
      SW_* events, so sparse_keymap_report_entry should do the same.
      Without the sync, events are accumulated in the kernel.
      Currently, no driver uses sparse-keymap for SW_* events, but
      it is required for the intel-vbtn platform driver to generate
      SW_TABLET_MODE events.

      Pull powerpc fixes from Michael Ellerman:
       "Some more powerpc fixes for 4.14.
        This is bigger than I like to send at rc7, but that's at least partly
        because I didn't send any fixes last week. If it wasn't for the IMC
        driver, which is new and getting heavy testing, the diffstat would
        look a bit better. I've also added ftrace on big endian to my test
        suite, so we shouldn't break that again in future.
         - A fix to the handling of misaligned paste instructions (P9 only),
           where a change to a #define has caused the check for the
           instruction to always fail.
         - The preempt handling was unbalanced in the radix THP flush (P9
           only). Though we don't generally use preempt we want to keep it
           working as much as possible.
         - Two fixes for IMC (P9 only), one when booting with restricted
           number of CPUs and one in the error handling when initialisation
           fails due to firmware etc.
         - A revert to fix function_graph on big endian machines, and then a
           rework of the reverted patch to fix kprobes blacklist handling on
           big endian machines.
