John Reiser noticed that a physical memory region was being mapped twice.
This patch fixes that, and it inlines the responsible function, as

Downgrade one of the MAC validity checks. If it's one that could be

Calculate TASK_SIZE at run-time by figuring out the host's VMSPLIT -
this is needed on i386 if UML is to run on hosts with varying VMSPLITs

This is a lot of cleanup. There are style fixes, printk fixes,
spelling fixes, mutex conversions, and small bug fixes.
This is all obviously for 2.6.25.
