Pull ipc regression fixes from Arnd Bergmann:
 "Fix ipc regressions from y2038 patches

  These are two regression fixes for bugs that got introduced during the
  system call rework that went into linux-5.1 but only bisected and
  fixed now:

   - One patch affects semtimedop() on many of the less common 32-bit
     architectures, this just needs a single-line bugfix.

   - The other affects only sparc64 and has a slightly more invasive
     workaround to apply the same change to sparc64 that was done to the
     generic code used everywhere else"
