Support for six syscall arguments for sparc64.
There is a minor stability issue which needs to be fixed (kernel panics upon entering kconsole from the
console task). |

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. |

Small change of code organization.
No functional difference. |

A quote from from SPARC V9 specification:
The Y register is deprecated; it is provided only for compatibility with previous versions
of the architecture. It should not be used in new SPARC-V9 software. It is
recommended that all instructions that reference the Y register (i.e., SMUL,
SMULcc, UMUL, UMULcc, MULScc, SDIV, SDIVcc, UDIV, UDIVcc, RDY, and
WRY) be avoided. See the appropriate pages in Appendix A, “Instruction Definitions,”
for suitable substitute instructions.
Still gcc is generating code which uses Y and some of the instructions above.
This change modifies the preemptible_handler() to preserve the Y register
across preemption. |

sparc64 update.
- Prototype userspace layer implementation that
at least relates to sparc64 and compiles cleanly.
- Fixes for kernel's preemptible_handler and code
related to running userspace.
- Enable userspace. Several dozen instructions
are now run in userspace! We are pretty near
the userspace milestone for sparc64. |
