With my tests (v4.4-10282-geae2177): Build results: total: 146 pass: 142 fail: 4 Failed builds: alpha:allmodconfig m68k:allmodconfig parisc:allmodconfig xtensa:allmodconfig Qemu test results: total: 96 pass: 94 fail: 2 Failed tests: arm64:smp:defconfig arm64:nosmp:defconfig arm64 qemu tests are broken for a different reason. There is a patch to fix it, but for some reason it didn't make it into mainline (yet). It is in -next, though. Guenter
