Recent kernels have the ability to remap keymap for USB keyboards via
EVIOCSKEYCODE ioctl (we allowed 0adjusting keymaps on PS/2 keyboards
for a long time). So instead of having the new parameter redefining
SysRq keycode Frederico can remap one of the keys on his keyboard to
generate KEY_SYSRQ. This way SysRq should still work if he plugs in
another USB keyboard that has SysRq key or a PS/2 keyboard.
