I implicitly asked you for a more verbose commit message.
For example, based on the info you provided as a reply above:

hw/vmmouse.c: Disable vmmouse on reboot
When a guest activated the vmmouse, following a reboot the vmmouse
stayed enabled and the PS/2 mouse was unusable. That way, when rebooting
to guests without vmmouse support the mouse would not work.
Fix this by disabling the vmmouse in its reset handler.

I have it queued for testing tomorrow - I am hoping this will fix a
0.15.1 mouse issue after kdump as well.
As a bugfix, it would definitely be a candidate for stable-1.0.
