fbcon: delay the start of the cursor timer until a con_switch()
As reported in Bugzilla Bug 9093, upon switching to X, a small rectangular
cursor can still be seen blinking in the upper left part of the screen. It is
fbcon's text cursor. This is caused by a strange ioctl(..., KDSETMODE,
KD_TEXT) call done by something in userspace, perhaps by X itself, while the
tty is still in graphics mode. And when the tty is in KD_TEXT mode, the
cursor timer is restarted.
Although this is a userspace problem, we can work around it by delaying the
restart of the cursor timer until an fbcon_switch() is called. In other
words, the cursor timer will not be restarted even if a KD_TEXT mode switch is
requested.
Regression potential: Present but low
