It's not just ARM32, I saw it on ARM64 as well and I'm pretty sure it appears on any bare metal "none" compiler. kernel.org host "nolibc" cross compilers (Arnd makes these): https://mirrors.edge.kernel.org/pub/tools/crosstool/ and those WORK, because they use the kernel minimal libc which defines __linux__. So a "nolibc" compiler works but not "none" compilers. I think the test robots all use Arnds nolibc compilers or the compilers from distributions so they don't see this. A typical example of breaking compilers: ARMs supported "none" compilers: https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads Yours, Linus Walleij

Linus reported that: After commit a103f46633fd the kernel stopped compiling for several ARM32 platforms that I am building with a bare metal compiler. Bare metal compilers (arm-none-eabi-) don't define __linux__. This is because the header <acpi/platform/acenv.h> is now in the include path for <linux/irq.h>: CC arch/arm/kernel/irq.o CC kernel/sysctl.o CC crypto/api.o In file included from ../include/acpi/acpi.h:22, from ../include/linux/fw_table.h:29, from ../include/linux/acpi.h:18, from ../include/linux/irqchip.h:14, from ../arch/arm/kernel/irq.c:25: ../include/acpi/platform/acenv.h:218:2: error: #error Unknown target environment 218 | #error Unknown target environment | ^~~~~ The issue is caused by the introducing of splitting out the ACPI code to support the new generic fw_table code. Rafael suggested [1] moving the fw_table.h include in linux/acpi.h to below the linux/mutex.h. Remove the two includes in fw_table.h. Replace linux/fw_table.h include in fw_table.c with linux/acpi.h.
