Ah, okay .. got it. Hm .. for some reason Tejun's emails are no longer making it into my inbox, there must be some filtering going on at the corporate IT level. I'll try and inquire IT about it ..

This is actually needed on every call to init_memory_mapping(), My patch 2/5 changes find_early_table_space() to find just enough space to map start to end. The pagetable_reserve() will then reserve what we actually used. Since init_memory_mapping() is called again and again with different start to end ranges, we find space for the page tables and reserve them every time. > > Yes, Jacob, you basically might want to carve out all functionality > from init_memory_mapping() which is independent from its start and end > args and do the carving in a pre-patch or two to 1/5. > > Thanks. > > -- > Regards/Gruss, > Boris. > -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
