      MIPS: traps: remove extra Tainted: line from __show_regs() output · 2d2ec2f7
      Petri Gynther authored
      __show_regs() calls show_regs_print_info(), which already outputs
      the Tainted: information. So, no need to output it twice.

      MIPS: Fix wrong CHECKFLAGS (sparse builds) with GCC 5.1 · 73d8f99c
      Aaro Koskinen authored
      GCC 5.1 defines __REGISTER_PREFIX__ to $. This will break sparse
      command line (and build fails with: /bin/sh: syntax error:
      unexpected "(") since make tries to expand starting with the dollar
      sign with a make variable. Prevent that by using double dollar sign.

      MIPS: Fix a preemption issue with thread's FPU defaults · 03dce595
      Maciej W. Rozycki authored
      Fix "BUG: using smp_processor_id() in preemptible" reported in accesses
      to thread's FPU defaults: the value to initialise FSCR to at program
      startup, the FCSR r/w mask and the contents of FIR in full FPU
      emulation, removing a regression introduced with 9b26616c [MIPS: Respect
      the ISA level in FCSR handling] and f6843626 [MIPS: math-emu: Set FIR
      feature flags for full emulation].
      
      Use `boot_cpu_data' to obtain the data from, following the approach that
      `cpu_has_*' macros take and avoiding the call to `smp_processor_id' made
      in the reference to `current_cpu_data'.  The contents of FSCR have to be
      consistent across processors in an SMP system, the settings there must
      not change as a thread is migrated across processors.  And the contents
      of FIR are guaranteed to be consistent in FPU emulation, by definition.

      MIPS: fix FP mode selection in lieu of .MIPS.abiflags data · 620b1550
      Paul Burton authored
      Commit 46490b57 ("MIPS: kernel: elf: Improve the overall ABI and FPU
      mode checks") reworked the ELF FP ABI mode selection logic, but when
      CONFIG_MIPS_O32_FP64_SUPPORT is enabled it breaks the use of binaries
      which have no PT_MIPS_ABIFLAGS program header & associated
      .MIPS.abiflags section.
      
      A default mode is selected based upon whether the ELF contains MIPS32 or
      MIPS64 code, but that selection is made in arch_elf_pt_proc.
      arch_elf_pt_proc only executes when a PT_MIPS_ABIFLAGS program header is
      found. If one is not found then arch_elf_pt_proc is never called, and no
      default overall_fp_mode value is selected. When arch_check_elf is
      called, both abi0 & abi1 are MIPS_ABI_FP_UNKNOWN which leads to both
      prog_req & interp_req being set to none_req. none_req matches none of
      the conditions for mode selection at the end of arch_check_elf, so
      overall_fp_mode is left untouched. Finally once mips_set_personality_fp
      is called the BUG() in the default case is then hit & the kernel likely
      panics.
      
      Fix this by moving the selection of a default overall mode to the start
      of arch_check_elf, which runs once per ELF executed regardless of
      whether it has a PT_MIPS_ABIFLAGS program header.

      drm: Zero out invalid vblank timestamp in drm_update_vblank_count. · fdb68e09
      Mario Kleiner authored
      Since commit 844b03f2 we make
      sure that after vblank irq off, we return the last valid
      (vblank count, vblank timestamp) pair to clients, e.g., during
      modesets, which is good.
      
      An overlooked side effect of that commit for kms drivers without
      support for precise vblank timestamping is that at vblank irq
      enable, when we update the vblank counter from the hw counter, we
      can't update the corresponding vblank timestamp, so now we have a
      totally mismatched timestamp for the new count to confuse clients.
      
      Restore old client visible behaviour from before Linux 3.17, but
      zero out the timestamp at vblank counter update (instead of disable
      as in original implementation) if we can't generate a meaningful
      timestamp immediately for the new vblank counter. This will fix
      this regression, so callers know they need to retry again later
      if they need a valid timestamp, but at the same time preserves
      the improvements made in the commit mentioned above.
