| Subject: MIPS: Fix enabling of DEBUG_STACKOVERFLOW |
| |
| From: James Hogan <james.hogan@imgtec.com> |
| |
| commit 5f35b9cd553fd64415b563497d05a563c988dbd6 upstream. |
| |
| Commit 334c86c494b9 ("MIPS: IRQ: Add stackoverflow detection") added |
| kernel stack overflow detection, however it only enabled it conditional |
| upon the preprocessor definition DEBUG_STACKOVERFLOW, which is never |
| actually defined. The Kconfig option is called DEBUG_STACKOVERFLOW, |
| which manifests to the preprocessor as CONFIG_DEBUG_STACKOVERFLOW, so |
| switch it to using that definition instead. |
| |
| Fixes: 334c86c494b9 ("MIPS: IRQ: Add stackoverflow detection") |
