[PATCH] sysrq: showBlockedTasks is sysrq-W
Change SysRq showBlockedTasks from sysrq-X to sysrq-W and show that in the
Help message.
It was previously done via X, but X is already used for Xmon on ppc & powerpc
platforms and this collision needs to be avoided.
All callers of register_sysrq_key() are now marked in the sysrq op/key table.
I didn't mark 'h' as Help because Help is just printed for any unknown key,
such as '?'.
Added some omitted sysrq key entries in the sysrq.txt file.
