This results in:

Building loongarch:defconfig ... failed
--------------
Error log:
arch/loongarch/kernel/machine_kexec.c: In function 'machine_crash_shutdown':
arch/loongarch/kernel/machine_kexec.c:252:9: error: implicit declaration of function 'machine_kexec_mask_interrupts' [-Wimplicit-function-declaration]
   252 |         machine_kexec_mask_interrupts();

... because  there is no loongarch specific version of machine_kexec_mask_interrupts()
in v6.12.y, and the function was generalized only with commit bad6722e478f5 ("kexec:
Consolidate machine_kexec_mask_interrupts() implementation") in v6.14.
