[PATCH] [230/275] fbcon: Bugfix soft cursor detection in Tile Blitting

[Andi Kleen]

2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Henry Nestler <henry.nestler@xxxxxxxxx>

commit d6244bc0ed0c52a795e6f4dcab3886daf3e74fac upstream.

Use mask 0x10 for "soft cursor" detection on in function tile_cursor.
(Tile Blitting Operation in framebuffer console).

The old mask 0x01 for vc_cursor_type detects CUR_NONE, CUR_LOWER_THIRD
and every second mode value as "software cursor". This hides the cursor
for these modes (cursor.mode = 0). But, only CUR_NONE or "software cursor"
should hide the cursor.
See also 0x10 in functions add_softcursor, bit_cursor and cw_cursor.
