Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] i386: make apic probe function non-init o struct genapic contains pointer to probe() function which is of type __init. Hence MODPOST generates warning if kernel is compiled with CONFIG_RELOCATABLE=y for i386. WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_summit' (at offset 0xc058b504) and 'apic_bigsmp' WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_bigsmp' (at offset 0xc058b5a4) and 'cpu.4471' WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_es7000' (at offset 0xc058b644) and 'apic_default' WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_default' (at offset 0xc058b6e4) and 'interrupt' o One of the possible options is to put special case check in MODPOST to not emit warnings for this case but I think it is not a very good option in terms of maintenance. o Another option is to make probe() function non __init. Anyway this function is really small so not freeing this memory after init is not a big deal. Secondly, from a programming perspective, probably genapic should not provide pointers to functions which have been freed as genapic is non __init and is used even after initialization is complete.
