Re: [PATCH 1/24] make atomic_read() behave consistently on alpha

The compiler is within its rights to read a 32-bit quantity 16 bits at

compiler writer that pulls such a dirty trick, but the C standard really
does permit this.

Code all over the kernel assumes that 32-bit reads/writes
are atomic so while such a compiler might be legal it certainly
can't compile Linux.
