Subject: [PATCH 15/87] drivers/tty/vt/vt_ioctl.c: fix KDFONTOP 32bit
 compatibility layer

commit cbcb8346054073d000ecac324763372d6abd44ac upstream.

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).
