There is a fallthrough comment being forgotten,
GCC complains about it:
arch/mips/kvm/emulate.c: In function kvm_mips_emulate_load:
arch/mips/kvm/emulate.c:1936:21: error: this statement may fall through
1936 | vcpu->mmio_needed = 1; /* unsigned */
| ~~~~~~~~~~~~~~~~~~^~~
arch/mips/kvm/emulate.c:1939:2: note: here
1939 | case lw_op:
Just fix it.

This is blocking KVM MIPS from build, so it needs to get into 5.9.
