| Subject: [PATCH 2/3] drm/nouveau: Prevent inlining of ramfuc_reg |
| |
| Apparently when gcc inlines it, it eats up 16 bytes on the stack every |
| time. Eventually we hit errors because our stack grew too much: |
| ramnve0.c:1383:1: error: the frame size of 1496 bytes is larger than 1024 bytes |
| We fix this by preventing inlining for this function. |
| |
| BUG=chromium:387296 |
| TEST=nouveau compiles on ARM |
