Message:

sparc64 work:

• hw_map() can now support up to 8M requests
• CPU stacks are now locked in DTLB of the respective processor
• kernel in the boot phase no longer relies on the stack provided by OpenFirmware
• instead of of doing FLUSHW during kernel startup, simply set the window state registers to the wanted state
• NWINDOW → NWINDOWS
• Add/fix some comments and copyrights.
