From: Joseph Lo <[email protected]> When building kernel with CONFIG_THUMB2_KERNEL, the data pointer in the assembly may not on the 4 byte alignment. Then causing a data abort when accessing the pointer. This patch add a ".align" flag in the head of the pointer. And always using 32-bit ADR Thumb instruction to make sure it won't build failure.
