From: Alexandre Ghiti <alexghiti@alexghiti.eu.rivosinc.com>
The EFI stub must not use any KASAN instrumented code as the kernel proper did not initialize the thread pointer and the mapping for the KASAN shadow region.
Avoid using the generic strcmp function, instead use the one in drivers/firmware/efi/libstub/string.c.
