Import the "gerbert" kernel I worked on earlier this year. It's a lot crappier than I remembered it. It's gonna need a lot of work. 2018-10-16 09:01:38 +00:00			`#pragma once`

A lot of hacking: - More work on funneling console output through Console. - init() now breaks off into a separate task ASAP. - ..this leaves the "colonel" task as a simple hlt idle loop. - Mask all IRQs on startup (except IRQ2 for slave passthru) - Fix underallocation bug in Task::allocateRegion(). - Remember how many times each Task has been scheduled. The panel and scheduling banner are disabled until I get things working nicely in the (brave) new Console world. 2018-10-22 09:15:16 +00:00			`void vga_putch_at(byte row, byte column, byte ch);`
