From 96951e0327ecc6f54125775ab807ba7dc9189b9b Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Mon, 28 Sep 2020 16:40:50 -0700 Subject: Fix objtool configure check The m4 objtool configure check can incorrectly fail because of a missing header in the test. This appears to be the result of a recent kernel change and was observed on the Fedora 5.8.11-200 kernel. In file included from /home/fedora/zfs/build/objtool/objtool.c:75: ./arch/x86/include/asm/frame.h:100:57: error: 'struct pt_regs' declared inside parameter list will not be visible outside of this definition or declaration [-Werror] The consequence of this is that the "stack_frame_non_standard" check is never run and HAVE_STACK_FRAME_NON_STANDARD is set incorrectly which results in a build failure. This change adds the appropriate header to the "objtool" check so it now behaves as intended.
