ipc: fix sparc64 ipc() wrapper (2019-09-07 21:42:25 +0200)

ipc: fix 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

- 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.

Arnd Bergmann (2):
ipc: fix semtimedop for generic 32-bit architectures
ipc: fix sparc64 ipc() wrapper
