I get a build error in arch/x86/kernel/setup.c:
CC arch/x86/kernel/setup.o arch/x86/kernel/setup.c: In function ‘ima_get_kexec_buffer’: arch/x86/kernel/setup.c:385:15: error: implicit declaration of function ‘ima_validate_range’ [-Wimplicit-function-declaration] 385 | ret = ima_validate_range(ima_kexec_buffer_phys, ima_kexec_buffer_size); | ^~~~~~~~~~~~~~~~~~ make[3]: *** [scripts/Makefile.build:250: arch/x86/kernel/setup.o] Fehler 1 make[2]: *** [scripts/Makefile.build:503: arch/x86/kernel] Fehler 2 make[1]: *** [scripts/Makefile.build:503: arch/x86] Fehler 2 make: *** [Makefile:2025: .] Fehler 2 root@linus:/usr/src/linux-stable-rc#
I always do my test builds with CONFIG_WEROR=Y, full .config attached.
The line causing the error seems to come from
73b97ee06bd63 x86/kexec: add a sanity check on previous kernel's ima kexec buffer [ Upstream commit c5489d04337b47e93c0623e8145fcba3f5739efd ]

If I revert 73b97ee06bd635433d1c429ecdbc9167da5de588, the build succeeds, and the kernel boots and seems to work fine.
I didn't even get a warning for this one :/
I'll drop it and push the -rc2 branch again for all affected kernels.
