# commit 80871482fd5cb1cb396ea232237a7d9c540854f9
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     x86: make ZERO_PAGE() at least parse its argument
#     
#     This doesn't really do anything, but at least we now parse teh
#     ZERO_PAGE() address argument so that we'll catch the most obvious errors
#     in usage next time they'll happen.
#     
#     See commit 6a5c5d26c4c6 ("rdma: fix build errors on s390 and MIPS due to
#     bad ZERO_PAGE use") what happens when we don't have any use of the macro
#     argument at all.
