Old gcc versions prior to 4.3 don't understand the 0b... syntax for
numbers, and this seems to be the only instance in the kernel, so better
use hexadecimal instead.

arch/arm/include/asm/kvm_mmu.h:127:38: error: invalid suffix "b101" on integer constant

Fixes: 159793001d7d ("ARM: KVM: force cache clean on page fault when caches are off")
