Nathan Chancellor b584bfbd7e ACPI: APEI: GHES: Disable KASAN instrumentation when compile testing with clang < 18 ... After a recent innocuous change to drivers/acpi/apei/ghes.c, building ARCH=arm64 allmodconfig with clang-17 or older (which has both CONFIG_KASAN=y and CONFIG_WERROR=y) fails with: drivers/acpi/apei/ghes.c:902:13: error: stack frame size (2768) exceeds limit (2048) in 'ghes_do_proc' [-Werror,-Wframe-larger-than] 902 | static void ghes_do_proc(struct ghes *ghes, | ^ A KASAN pass that removes unneeded stack instrumentation, enabled by default in clang-18 [1], drastically improves stack usage in this case. To avoid the warning in the common allmodconfig case when it can break the build, disable KASAN for ghes.o when compile testing with clang-17 and older. Disabling KASAN outright may hide legitimate runtime issues, so live with the warning in that case; the user can either increase the frame warning limit or disable -Werror, which they should probably do when debugging with KASAN anyways.
