From 6a5c5d26c4c6c3cc486fef0bf04ff9551132611b Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 29 Apr 2019 09:48:53 -0700 Subject: [PATCH] rdma: fix build errors on s390 and MIPS due to bad ZERO_PAGE use The parameter to ZERO_PAGE() was wrong, but since all architectures except for MIPS and s390 ignore it, it wasn't noticed until 0-day reported the build error.
