From: Mikulas Patocka <mpatocka@redhat.com> stable inclusion from stable-v5.10.133 commit 236b959da9d145c311f9daa65e3fbbe1a3c9c9af category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5YVKO Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit 22682a07acc308ef78681572e19502ce8893c4d4 upstream. Commit c087c6e7b551 ("objtool: Fix type of reloc::addend") failed to appreciate cross building from ILP32 hosts, where 'int' == 'long' and the issue persists. As such, use s64/int64_t/Elf64_Sxword for this field and suffer the pain that is ISO C99 printf formats for it.
