This creates a bit of a dependency headache since we need to copy
With this patch applied, it seems this fixes these asm-related builds: linux-powerpc-bamboo_defconfig linux-powerpc-cell_defconfig linux-powerpc-ebony_defconfig linux-powerpc-katmai_defconfig linux-powerpc-ppc44x_defconfig linux-powerpc-rainier_defconfig linux-powerpc-sam440ep_defconfig linux-powerpc-sequoia_defconfig linux-powerpc-taishan_defconfig ...while three remain unresolved: linux-powerpc-asp8347_defconfig linux-powerpc-mvme5100_defconfig linux-powerpc-ppc64e_defconfig Of course I cannot verify the resulting kernel binaries, but I guess you'd push this patch. The PR for the ICE is being actively worked on, just started a GCC build with the suggested patch. MfG, JBG --
