Changed the structure of header files, which have sun4u and sun4v versions. Implemented some sun4v TSB functions. |

The Ultimate Solution To Illegal Virtual Aliases.
It is better to avoid them completely than to fight them.
Switch the sparc64 port to 16K pages. The TLBs and TSBs
continue to operate with 8K pages only. Page tables and
other generic parts operate with 16K pages.
Because the MMU doesn't support 16K directly, each 16K
page is emulated by a pair of 8K pages. With 16K pages,
illegal aliases cannot be created in 16K D-cache. |

Introduce page colors. So far, only sparc64 uses correct page color bits. Other architectures have a dummy define
specifying zero bits for a page color.
There is a new check of page color in as_area_share(). Because of lack of support for this in the userspace, the
check has been #ifef'ed out. |

sparc64 code to support physical memory that starts on non-zero addresses.
Still needs to be tested on systems with such setup. |

sparc64 work.
More bits needed to reach the userspace milestone were added.
The preemptible_handler(), still a prototype, now contains all functionality it needs.
Some sanitation was added to functions expecting page-aligned pointers to
userspace window buffer. |

sparc64 work.
1. Formatting fixes.
2. When writing to DMMU ASI's, simple membar() can be used in place of flush().
3. Substantial changes in the way the TLB is taken over.
4. Remove unneeded functions.
This is the first revision that also runs on a real world Ultra 5 with UltraSPARC IIi
processor.
Note that 3. needs further work as the current implementation depends on the fact
that the compiler will use registers for local variables in take_over_tlb_and_tt().
Rewrite of that function into assembly is to follow. |
