Here's how I know you haven't tested this on 32-bit:
arch/x86/kernel/cpu/microcode/intel.c: In function ‘print_ucode’:
arch/x86/kernel/cpu/microcode/intel.c:344:33: error: unused variable ‘mc’ [-Werror=unused-variable]
344 | struct microcode_intel *mc;
| ^~
cc1: all warnings being treated as errors
make[5]: *** [scripts/Makefile.build:252: arch/x86/kernel/cpu/microcode/intel.o] Error 1
make[4]: *** [scripts/Makefile.build:504: arch/x86/kernel/cpu/microcode] Error 2
make[3]: *** [scripts/Makefile.build:504: arch/x86/kernel/cpu] Error 2
make[2]: *** [scripts/Makefile.build:504: arch/x86/kernel] Error 2
make[1]: *** [scripts/Makefile.build:504: arch/x86] Error 2
make[1]: *** Waiting for unfinished jobs....
make: *** [Makefile:2008: .] Error 2
Testing is overrated, right?
The maintainers can do that, ofc.
