Rework support for virtually indexed cache.
Instead of repeatedly flushing the data cache, which was a huge overkill, refuse to create an illegal address alias
in the kernel (again) and allocate appropriate page color in userspace instead. Extend the detection also to
SYS_PHYSMEM_MAP syscall.
Add support for tracking physical memory areas mappable by SYS_PHYSMEM_MAP.
Lots of coding style changes. |

sparc64 work:
- Experimental support for TSB (Translation Storage Buffer). |

- Create a dedicated slab cache for as_t objects and switch from malloc/free to slab_alloc/slab_free for
them.
- Slightly fix and improve both the kernel and userspace atomic_add() on sparc64.
- More TSB work on the sparc64 front. |

Fix bug in mm/as.c:
- as_area_destroy() should not work with AS but as
sparc64 work:
- start implementing TSB support |

C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64. |

sparc64 work.
- the syscall wrapper needs to use the "memory"
clobber specifier to prevent over-optimization.
- on sparc64, the user address space spans the whole
64-bit space and therefore the macro
USER_ADDRESS_SPACE_SIZE_ARCH, as it was defined,
overflows to 0
- stop using USER_ADDRESS_SPACE_SIZE_ARCH and define
MAX_HEAP_SIZE instead
- in our situation when kernel and user address spaces
are separate, the G (global) bit cannot be used
(there is no point in it anymore)
- add the DEBUG() macro to stdio.h; DEBUG() uses
SYS_IO and is a good debugging tool for getting
early userspace to work |

sparc64 work.
Define the istate structure.
Move the identity-mapping handler to assembly.
Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it.
Little bit of formatting and indentation. |

Added 256K slab, so that AMD can boot (until ELF loader is fixed).
Added AS_AREA_RECV so that the caller can receive AS_AREA. |

Move the sharing functionality to address space area backends.
Add backend for continuous regions of physical memory.
Sharing for these areas works automagically now. |
