From caf539cd1087f7c36b9c4df271575e9aee49fde5 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Thu, 25 Oct 2018 10:36:19 -0700 Subject: sparc: Fix VDSO build with older binutils. Older versions of bintutils do not allow symbol math across different segments on sparc: ==================== Assembler messages: 99: Error: operation combines symbols in different segments ==================== This is controlled by whether or not DIFF_EXPR_OK is defined in gas/config/tc-*.h and for sparc this was not the case until mid-2017. So we have to patch between %stick and %tick another way. Do what powerpc does and emit two versions of the relevant functions, one using %tick and one using %stick, and patch the symbols in the dynamic symbol table.
