      drm: Don't oops in drm_calc_timestamping_constants() if drm_vblank_init() wasn't called · 0c545ac4
      Ville Syrjälä authored
      Seems the crtc helpers call drm_calc_timestamping_constants()
      unconditionally even if the driver didn't initialize vblank support by
      calling drm_vblank_init(). That used to be OK since the constants were
      stored under drm_crtc.
      
      However I broke this with
      commit eba1f35d
      
       ("drm: Move timestamping constants into drm_vblank_crtc")
      when I moved the constants to live inside the drm_vblank_crtc struct
      instead. If drm_vblank_init() isn't called, we don't allocate these
      structures, and so drm_calc_timestamping_constants() will oops.
      
      Fix it by adding a check into drm_calc_timestamping_constants() to see
      if vblank support was initialized at all. And to keep in line with other
      such checks, also toss in a check and warn for the case where vblank
      support was initialized, but the wrong number of crtcs was specified.
      
      Fixes the following sort of oops:

       "Four changes:
      
         - x86: work around two nasty cases where a benign exception occurs
           while another is being delivered.  The endless stream of exceptions
           causes an infinite loop in the processor, which not even NMIs or
           SMIs can interrupt; in the virt case, there is no possibility to
           exit to the host either.
      
         - x86: support for Skylake per-guest TSC rate.  Long supported by
           AMD, the patches mostly move things from there to common
           arch/x86/kvm/ code.
      
         - generic: remove local_irq_save/restore from the guest entry and
           exit paths when context tracking is enabled.  The patches are a few
           months old, but we discussed them again at kernel summit.  Andy
           will pick up from here and, in 4.5, try to remove it from the user
           entry/exit paths.

         - kfree()-related fixup for the recently introduced CPPC cpufreq
           frontend (Markus Elfring).

         - cpufreq core optimization related to the handling of delayed work
           items used by governors (Viresh Kumar).

      On a cross-toolchain without glibc support, libgcov may not be

      We don't really want to link libgcov into the vdso anyway, so

      cpus_have_hwcap() is defined as a 'static' function an only used in

      the only user is disabled:
      
      arch/arm64/kernel/cpufeature.c:699:13: warning: 'cpus_have_hwcap' defined but not used [-Wunused-function]

      number of days in that month.  Also put the month number validation before
      doing the lookup so as not to risk overrunning the array.

        family of SoCs, various SoCs from Renesas and Broadcom as well as the

        Further existing drivers are extended to support a wider range of
        hardware.
      
        The remaining patches are minor fixes and cleanups across the board.
      
        Note that one of the patches included in this pull request is against
        arch/unicore32.  I've included it here because I couldn't get a
        response from Guan Xuetao and I consider the change low-risk.
        Equivalent patches have been merged and tested in Samsung and PXA
        trees.  The goal is to finally get rid of legacy code paths that have
        repeatedly been causing headaches"
