I get a build error in arch/x86/kernel/setup.c:

CC arch/x86/kernel/setup.o

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 ]

via

136114e0abf03005e182d75761ab694648e6d388 "Merge tag 'mm-nonmm-stable-2026-02-12-10-48' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm"
Pull non-MM updates from Andrew Morton


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.
