Peter Anvin <hpa@xxxxxxxxxxxxxxx> CommitDate: Mon, 25 Feb 2013 10:47:09 -0800 ACPI: Overriding ACPI tables via initrd only works with an initrd and on X86 Reflect this dependency in Kconfig, to prevent build failures. Shorten the config description as suggested by Borislav Petkov. Finding a suitable memory area to store the modified table(s) has been taken over from arch/x86/kernel/setup.c and makes use of max_low_pfn_mapped: memblock_find_in_range(0, max_low_pfn_mapped,...) This one is X86 specific. It may not be hard to extend this functionality for other ACPI aware architectures if there is need for. For now make this feature only available for X86 to avoid build failures on IA64, compare with: https://bugzilla.kernel.org/show_bug.cgi?id=54091 Signed-off-by: Thomas Renninger <trenn@xxxxxxx> Link: http://lkml.kernel.org/r/1361538742-67599-3-git-send-email-trenn@xxxxxxx Signed-off-by: H.
