51 * Leave these fn's as byte accesses because it is safe
52 * across architectures. Clever usage of 32 bit access
53 * will create problems on some hosts.
55 * Note that the pointer in memory might be unaligned.
57 * On some CPU's, i.e. ARM7, the 2 lsb are ignored for 32
58 * bit access, on others it will cause an exception and
59 * on e.g. x86, it works the same as if aligned.
