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. |

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.
- 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 |

big code cleanup, compile with -Wall -Werror to enforce better coding
there is currently one warning that requires attention, please review |
