May I suggest trying: $ grep RESOURCES_64BIT=y arch/*/configs/* arch/*/defconfig to locate those architectures which use this? FYI, that grep says ARM, ia64, mips, parisc, powerpc, PPC, s390, sparc64, and x86 use this feature. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of:
