From e7bc47b16622d1016b3b77bbdb20fb9e213045f2 Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Thu, 11 Apr 2024 13:46:16 -0300 Subject: s390: Stop using weak symbols for __iowrite64_copy() Complete switching the __iowriteXX_copy() routines over to use #define and arch provided inline/macro functions instead of weak symbols. S390 has an implementation that simply calls another memcpy function. Inline this so the callers don't have to do two jumps.
