Argh, looks like I missed something important in testing: a WARN from check_early_ioremap_leak. Looks like moving the reclamation of the EFI memory map that late makes check_early_ioremap_leak figure that it won't get reclaimed at all. As far as I can tell, ioremap won't work that early; EFI really does need to use early_ioremap. Since at the moment we don't seem to have any other drivers that need to access boot services memory, any objection to moving efi_free_boot_services back to just after ACPI? - Josh Triplett -- 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/
