Input: amikbd - allocate temporary keymap buffer on the stack
Allocate the temporary buffer needed for initialization of the console keyboard maps (512 bytes, as NR_KEYS = 256) on the stack instead of statically, to reduce kernel size. add/remove: 0/1 grow/shrink: 0/0 up/down: 0/-512 (-512) function old new delta temp_map 512 - -512 Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
