| |
2.6.35-longterm review patch. If anyone has any objections, please let me know.
------------------ From: Henry Nestler <henry.nestler@gmail.com>
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.
