keymap: hash table collisions

Binary package hint: udev

<mezcalero> [22:31:27] pitti: i just ran udev through llvm-clang-analyzer
<mezcalero> [22:32:22] pitti: as it turns out the keymap in the kernel is not bijective
<mezcalero> [22:32:36] pitti: i.e. more than one name are mapped to the same key
<mezcalero> [22:33:08] example: HANGEUL and HANGUEL
<mezcalero> [22:33:26] pitti: now, the perfect hashtable that is generated from that is actually not that perfect due to that
<mezcalero> [22:33:31] and weird things might happen
<mezcalero> [22:33:40] pitti: this probably should be fixed in some way
<mezcalero> [22:33:52] pitti: probably by preprocessing input.h in some and filtering out duplicates
<mezcalero> [22:34:01] and sticking to the first names defined there in case of an ambiguity
<mezcalero> [22:34:11] pitti: just wanted to ping you about that...
<mezcalero> [22:34:57] pitti: http://fpaste.org/t6ow/
<mezcalero> [22:37:31] pitti: the fix is probably as easy as simply filtering KEY_HANGUEL, KEY_COFFEE, KEY_MIN_INTERESTING from the table
<mezcalero> [22:37:53] pitti: because they seem to be irrelevant as real keys
