#     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"
#     
#     * tag 'ipc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic:
#       ipc: fix sparc64 ipc() wrapper
