From cbcb8346054073d000ecac324763372d6abd44ac Mon Sep 17 00:00:00 2001 From: Samuel Thibault Date: Fri, 3 Feb 2012 15:37:15 -0800 Subject: [PATCH] drivers/tty/vt/vt_ioctl.c: fix KDFONTOP 32bit compatibility layer KDFONTOP(GET) currently fails with EIO when being run in a 32bit userland with a 64bit kernel if the font width is not 8. This is because of the setting of the KD_FONT_FLAG_OLD flag, which makes con_font_get return EIO in such case. This flag should *not* be set for KDFONTOP, since it's actually the whole point of this flag (see comment in con_font_set for instance).
