3.18-stable review patch. If anyone has any objections, please let me know.
------------------ From: Arnd Bergmann <[email protected]> commit f6aafac184a3e46e919769dd4faa8bf0dc436534 upstream. aarch64-linux-gcc-7 complains about code it doesn't fully understand: drivers/infiniband/hw/qib/qib_iba7322.c: In function 'qib_7322_txchk_change': include/asm-generic/bitops/non-atomic.h:105:35: error: 'shadow' may be used uninitialized in this function [-Werror=maybe-uninitialized] The code is right, and despite trying hard, I could not come up with a version that I liked better than just adding a fake initialization here to shut up the warning.
