      [media] rcar-fcp: Make sure rcar_fcp_enable() returns 0 on success · 7892a1f6
      Geert Uytterhoeven authored
      When resuming from suspend-to-RAM on r8a7795/salvator-x:
      
          dpm_run_callback(): pm_genpd_resume_noirq+0x0/0x90 returns 1
          PM: Device fe940000.fdp1 failed to resume noirq: error 1
          dpm_run_callback(): pm_genpd_resume_noirq+0x0/0x90 returns 1
          PM: Device fe944000.fdp1 failed to resume noirq: error 1
          dpm_run_callback(): pm_genpd_resume_noirq+0x0/0x90 returns 1
          PM: Device fe948000.fdp1 failed to resume noirq: error 1
      
      According to its documentation, rcar_fcp_enable() returns 0 on success
      or a negative error code if an error occurs.  Hence
      fdp1_pm_runtime_resume() and vsp1_pm_runtime_resume() forward its return
      value to their callers.
      
      However, rcar_fcp_enable() forwards the return value of
      pm_runtime_get_sync(), which can actually be 1 on success, leading to
      the resume failure above.
      
      To fix this, consider only negative values returned by
      pm_runtime_get_sync() to be failures.

      parisc: Fix order of EREFUSED define in errno.h · 3eb53b20
      Helge Deller authored
      When building gccgo in userspace, errno.h gets parsed and the go include file
      sysinfo.go is generated.
      
      Since EREFUSED is defined to the same value as ECONNREFUSED, and ECONNREFUSED
      is defined later on in errno.h, this leads to go complaining that EREFUSED
      isn't defined yet.
      
      Fix this trivial problem by moving the define of EREFUSED down after
      ECONNREFUSED in errno.h (and clean up the indenting while touching this line).

      parisc: Fix automatic selection of cr16 clocksource · ae141830
      Helge Deller authored
      Commit 54b66800 (parisc: Add native high-resolution sched_clock()
      implementation) added support to use the CPU-internal cr16 counters as reliable
      clocksource with the help of HAVE_UNSTABLE_SCHED_CLOCK.
      
      Sadly the commit missed to remove the hack which prevented cr16 to become the
      default clocksource even on SMP systems.

      Make the hardened user-copy code depend on having a hardened allocator · 6040e576
      Linus Torvalds authored
      The kernel test robot reported a usercopy failure in the new hardened
      sanity checks, due to a page-crossing copy of the FPU state into the
      task structure.
      
      This happened because the kernel test robot was testing with SLOB, which
      doesn't actually do the required book-keeping for slab allocations, and
      as a result the hardening code didn't realize that the task struct
      allocation was one single allocation - and the sanity checks fail.
      
      Since SLOB doesn't even claim to support hardening (and you really
      shouldn't use it), the straightforward solution is to just make the
      usercopy hardening code depend on the allocator supporting it.
