* [PATCH] x86_64: actively synchronize vmalloc area when registering certain ↵Jan Beulich2006-03-251-0/+28
| | | | | | | | | | | | | | | | | | | | | | | callbacks While the modular aspect of the respective i386 patch doesn't apply to x86-64 (as the top level page directory entry is shared between modules and the base kernel), handlers registered with register_die_notifier() are still under similar constraints for touching ioremap()ed or vmalloc()ed memory. The likelihood of this problem becoming visible is of course significantly lower, as the assigned virtual addresses would have to cross a 2**39 byte boundary. This is because the callback gets invoked (a) in the page fault path before the top level page table propagation gets carried out (hence a fault to propagate the top level page table entry/entries mapping to module's code/data would nest infinitly) and (b) in the NMI path, where nested faults must absolutely not happen, since otherwise the IRET from the nested fault re-enables NMIs, potentially resulting in nested NMI occurences.

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!
