OK, so this has passed my defconfig and allnoconfig for xtensa compile test, allyesconfig has failed due to some unrelated reasons: clk-qoriq.c:(.init.text+0x3ebd3): dangerous relocation: l32r: literal target out of range (try using text-section-literals): (.init.literal+0x17c60) and zillions of similar... The same error is without the patch I do not have a crosscompiler[1] for sh arch so I couldn't have tested it but there shouldn't be any issues in principal. I will send two patches as a follow up. --- [1] https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/ doesn't seem to have it. -- Michal Hocko SUSE Labs -- To unsubscribe from this list: send the line "unsubscribe linux-s390" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
