In total, we seem to be nine patches short of a clean build now, which is the best we've had since kernelci added MIPS builds (we had a clean build for one day before that). > allmodconfig (arm) — PASS, 0 errors, 7 warnings, 0 section mismatches > > Warnings: > drivers/iio/adc/rcar-gyroadc.c:429:27: warning: 'num_channels' may be used > uninitialized in this function [-Wmaybe-uninitialized] > drivers/iio/adc/rcar-gyroadc.c:426:22: warning: 'sample_width' may be used > uninitialized in this function [-Wmaybe-uninitialized] > drivers/iio/adc/rcar-gyroadc.c:428:23: warning: 'channels' may be used > uninitialized in this function [-Wmaybe-uninitialized] > drivers/iio/adc/rcar-gyroadc.c:398:26: warning: 'adcmode' may be used > uninitialized in this function [-Wmaybe-uninitialized] > drivers/media/platform/coda/imx-vdoa.c:333:181: warning: passing argument 1 > of '__platform_driver_register' discards 'const' qualifier from pointer > target type [-Wdiscarded-qualifiers] > drivers/media/platform/coda/imx-vdoa.c:333:625: warning: passing argument 1 > of 'platform_driver_unregister' discards 'const' qualifier from pointer > target type [-Wdiscarded-qualifiers] Covered in my reply to Olof's build bot. > drivers/usb/gadget/udc/atmel_usba_udc.c:632:550: warning: 'ept_cfg' may be > used uninitialized in this function [-Wmaybe-uninitialized] My patch was acked, but not picked up by Felipe or Greg so far: https://www.spinics.net/lists/linux-usb/msg153162.html > allmodconfig (x86) — PASS, 0 errors, 5 warnings, 0 section mismatches > > Warnings: > lib/raid6/recov_avx512.c:387:2: warning: #warning "your version of binutils > lacks AVX512 support" [-Wcpp] long-standing problem on the kernelci.org x86 toolchain, the only solution is to update the build bot. > drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c:7263:2: warning: missing braces around > initializer [-Wmissing-braces] > drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c:7263:2: warning: (near initialization > for 'ce_payload.regular') [-Wmissing-braces] > drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c:7290:2: warning: missing braces around > initializer [-Wmissing-braces] > drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c:7290:2: warning: (near initialization > for 'de_payload.regular') [-Wmissing-braces] This only happens on old compilers.

This might take some more time, but it's been like this from the start with KASAN. > ip27_defconfig (mips) — FAIL, 2 errors, 0 warnings, 0 section mismatches > > Errors: > drivers/net/ethernet/qlogic/qlge/qlge_main.c:4819:1: error: insn does not > satisfy its constraints: > drivers/net/ethernet/qlogic/qlge/qlge_main.c:4819:1: internal compiler > error: in extract_constrain_insn, at recog.c:2190 broken gcc release, apparently fixed in gcc-7 (can't reproduce here at least).
