Catalin Marinas fd522a8dec ARM: 6006/1: ARM: Use the correct NOP size in memmove for Thumb-2 kernel builds ...

When compiling the kernel to Thumb-2, using a 16-bit NOP in the
memmove() implementation causes the preceding ADD PC instruction to
branch incorrectly in the middle of a 32-bit LDR or STR instruction. The
memmove() code is now similar to the memcpy() template.
