| Subject: objtool: Silence more KCOV warnings, part 2 |
| |
| From: Josh Poimboeuf <jpoimboe@kernel.org> |
| |
| commit 55c78035a1a8dfb05f1472018ce2a651701adb7d upstream. |
| |
| Similar to GCOV, KCOV can leave behind dead code and undefined behavior. |
| Warnings related to those should be ignored. |
| |
| The previous commit: |
| |
| 6b023c784204 ("objtool: Silence more KCOV warnings") |
| |
| ... only did so for CONFIG_CGOV_KERNEL. Also do it for CONFIG_KCOV, but |
| for real this time. |
| |
| Fixes the following warning: |
| |
| vmlinux.o: warning: objtool: synaptics_report_mt_data: unexpected end of section .text.synaptics_report_mt_data |
| |
| Fixes: 6b023c784204 ("objtool: Silence more KCOV warnings") |
