There is still a bunch. For v5.15-rc1-27-gb7213ffa0e58: alpha: drivers/net/ethernet/3com/3c515.c: In function 'corkscrew_start_xmit': drivers/net/ethernet/3com/3c515.c:1053:22: error: cast from pointer to integer of different size That is a typecast from a pointer to an int, which is then sent to an i/o port. That driver should probably be disabled for 64-bit builds. --- drivers/net/wan/lmc/lmc_main.c: In function 'lmc_softreset': drivers/net/wan/lmc/lmc_main.c:1782:50: error: passing argument 1 of 'virt_to_bus' discards 'volatile' qualifier from pointer target type and several other similar errors. patch: https://lore.kernel.org/lkml/20210909050033.1564459-1-linux@xxxxxxxxxxxx/ Arnd sent an Ack, but it doesn't look like it was picked up. --- drivers/net/hamradio/6pack.c: In function 'sixpack_open': drivers/net/hamradio/6pack.c:71:41: error: unsigned conversion from 'int' to 'unsigned char' changes value from '256' to '0' patch: https://lore.kernel.org/lkml/20210909035743.1247042-1-linux@xxxxxxxxxxxx/ David says it is wrong, and I don't know the code well enough to feel comfortable touching that code. That may be a lost cause. "depends on BROKEN if ALPHA" may be appropriate here. === arm: drivers/cpufreq/vexpress-spc-cpufreq.c: In function 've_spc_cpufreq_exit': drivers/cpufreq/vexpress-spc-cpufreq.c:454:13: error: unused variable 'cur_cluster' patch: https://patchwork.kernel.org/project/linux-arm-kernel/patch/20210909184714.153068-1-linux@xxxxxxxxxxxx/ === m68k: arch/m68k/mvme147/config.c: In function 'mvme147_hwclk': arch/m68k/mvme147/config.c:174:2: error: #warning check me!

Patch: https://patchwork.kernel.org/project/linux-watchdog/patch/20210913073220.1159520-1-liu.yun@xxxxxxxxx/ I'll need to get Wim to push it. === parisc: arch/parisc/kernel/setup.c: In function 'start_parisc': arch/parisc/kernel/setup.c:387:28: error: '__builtin_memcmp_eq' specified bound 8 exceeds source size 0 Waiting for the absolute_pointer patch === riscv32, riscv64: drivers/gpu/drm/rockchip/cdn-dp-core.c:1126:12: error: 'cdn_dp_resume' defined but not used patch: https://patchwork.kernel.org/project/linux-rockchip/patch/20200925215524.2899527-3-sam@xxxxxxxxxxxx/ Looks like that and similar patches were submitted several times, but never picked up. === s390: drivers/spi/spi-tegra20-slink.c:1200:12: error: 'tegra_slink_runtime_resume' defined but not used drivers/spi/spi-tegra20-slink.c:1188:12: error: 'tegra_slink_runtime_suspend' defined but not used patch: https://patchwork.kernel.org/project/spi-devel-general/patch/20210907045358.2138282-1-linux@xxxxxxxxxxxx/ marked as accepted, so should hopefully find its way upstream soon. --- lib/test_kasan.c: In function 'kasan_alloca_oob_right': lib/test_kasan.c:782:1: error: 'kasan_alloca_oob_right' uses dynamic stack allocation and a couple of similar errors. s390 has a special configuration option to enable warnings on dynamic stack allocations. A patch to remove that option is pending according to s390 maintainers. --- drivers/gpu/drm/rockchip/cdn-dp-core.c:1126:12: error: 'cdn_dp_resume' defined but not used Same as for riscv. === xtensa: Various stack frame errors (more than 50). drivers/video/fbdev/omap2/omapfb/dss/dsi.c: In function 'dsi_dump_dsidev_irqs': drivers/video/fbdev/omap2/omapfb/dss/dsi.c:1623:1: error: the frame size of 1104 bytes is larger than 1024 bytes Patch: https://lore.kernel.org/lkml/20210912025235.3514761-1-linux@xxxxxxxxxxxx/ Should find its way upstream through mmotm.
