* remotes/kraxel/tags/input-20171023-pull-request:
ui: pull in latest keycodemapdb
ui: normalize the 'sysrq' key into the 'print' key
ps2: fix scancodes sent for Ctrl+Pause key combination
ps2: fix scancodess sent for Pause key in AT set 1
ps2: fix scancodes sent for Shift/Ctrl+Print key combination
ps2: fix scancodes sent for Alt-Print key combination (aka SysRq)
ui: use correct union field for key number
ui: fix crash with sendkey and raw key numbers
input: use hex in ps2 keycode trace events
