| BenC | it's something in v4l2 | 12:25 |
| kylem | ok | 12:25 |
| BenC | it'll show up in modpost | 12:26 |
| BenC | I don't understand why x86_64 and sparc64 didn't already show it | 12:26 |
| BenC | oh, well, probably because di2 isn't needed on 64-bit | 12:27 |
| BenC | well, it didn't show on x86 :) | 12:27 |
| kylem | is it ppc64? | 12:28 |
| BenC | nope, ppc32 | 12:28 |

| kylem | void foo(void); EXPORT_SYMBOL(foo); is pretty evil, i think it will work for my atheros hack too. | 04:43 |

| kylem | mjg59, it's the right answer on a whole lot of platforms. | 05:32 |

| BenC | mjg59: It seems to be what othr architectures do | 05:32 |

| mjg59 | Yeah | 05:32 |
| kylem | we /aren't/ linking libgcc. | 05:32 |

| kylem | sorry, was eating lunch | 07:05 |
| mjg59 | BenC: Hi | 07:06 |
| BenC | mjg59: Can you look at the release/completion patch we have in some of the pcmcia controller drivers and tell me if we still need them? | 07:06 |
| BenC | I'm getting a softlockup in i82365 on my P4 and I think it might be related to those changes | 07:07 |
| mjg59 | release/completition patch? | 07:08 |
| BenC | it adds a release() call back to the platform device, and it calls complete()...module exit does a wait_for_completion() on it | 07:10 |
| BenC | it's was suspend related, IIRC | 07:10 |
| BenC | been around since breezy I think | 07:10 |
| mjg59 | Uh. | 07:11 |
| mjg59 | Not actually sure if it was anything to do with me. | 07:11 |
| BenC | I thought I remembered you asking me to put it back in dapper because I left it out...maybe I am misremembering :) | 07:11 |
| BenC | if you don't know anything about it, I'm killing it | 07:11 |
| mjg59 | Looks like it came from http://lists.infradead.org/pipermail/linux-pcmcia/2004-March/000598.html | 07:12 |
| BenC | that patch isn't causing the softlockup anyway | 07:13 |
| BenC | I think that's uneeded now...the drivers are using platform_device_alloc() which has: | 07:15 |
| BenC | pa->pdev.dev.release = platform_device_release; | 07:15 |
| BenC | oops, I didn't actually use the unpatched one...reverting that patch fixes it | 07:16 |
