Add Peter Zijlstra's copyright to the uprobes code, whose
contributions to the uprobes code are not visible in the Git
history, because they were backmerged.
Also update existing copyright notices to the year 2012.

Few cleanups suggested by Ingo Molnar.
- Rename struct uprobe_arch_info to struct arch_uprobe.
- Move insn from struct uprobe to struct arch_uprobe.
- Make arch specific uprobe functions to accept struct arch_uprobe
instead of struct uprobe.
- Move struct uprobe to kernel/uprobes.c from include/linux/uprobes.h

uprobe_opcode_sz refers to the smallest instruction size for
that architecture. UPROBES_BKPT_INSN_SIZE refers to the size of
the breakpoint instruction for that architecture.
For now we are assuming that both uprobe_opcode_sz and
UPROBES_BKPT_INSN_SIZE are the same for all archs and hence
removing uprobe_opcode_sz in favour of UPROBES_BKPT_INSN_SIZE.
However if we have to support architectures where the smallest
instruction size is different from the size of breakpoint
instruction, we may have to re-introduce uprobe_opcode_sz.
