Masahiro Yamada f993d24a94 s390: fix -Wundef warning for CONFIG_KERNEL_ZSTD ... Since commit 80b6093b55 ("kbuild: add -Wundef to KBUILD_CPPFLAGS for W=1 builds"), building with W=1 detects misuse of #(el)if. $ make W=1 ARCH=s390 CROSS_COMPILE=s390x-linux-gnu- [snip] arch/s390/boot/decompressor.c:28:7: warning: "CONFIG_KERNEL_ZSTD" is not defined, evaluates to 0 [-Wundef] 28 | #elif CONFIG_KERNEL_ZSTD | ^~~~~~~~~~~~~~~~~~ This issue has been hidden because arch/s390/boot/Makefile overwrites KBUILD_CFLAGS, dropping -Wundef. CONFIG_KERNEL_ZSTD is a bool option. #elif defined() should be used. The line #ifdef CONFIG_KERNEL_BZIP2 is fine, but I changed it for consistency.
