Drop support to compile the kernel with gcc versions older than 3.3.3. This allows us to use the "Q" inline assembly contraint on some more inline assemblies without duplicating a lot of complex code (e.g. __xchg and __cmpxchg). The distinction for older gcc versions can be removed which saves a few lines and simplifies the code.
