x86: add the "print code before the trapping instruction" feature to 64 bit
The 32 bit x86 tree has a very useful feature that prints the Code: line for the code even before the trapping instrution (and the start of the trapping instruction is then denoted with a <>). Unfortunately, the 64 bit x86 tree does not yet have this feature, making diagnosing backtraces harder than needed. This patch adds this feature in the same was as the 32 bit tree has (including the same kernel boot parameter), and including a bugfix to make the code use probe_kernel_address() rarther than a buggy (deadlocking) __get_user.
