[PATCH] fbcon: Use persistent allocation for cursor blinking
Every time the console cursor blinks, we do a kmalloc/kfree pair. This
patch turns that into a single allocation.
This allocation was the most frequent kmalloc I saw on my test box.
[adaplas]
Per Alan's suggestion, move global variables to fbcon's private structure.
This would also avoid resource leaks when fbcon is unloaded.
