3908 6174 d 14 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3246 6368 d 15 h jermar /trunk/ cstyle  
3029 6436 d 18 h decky /trunk/kernel/generic/ fix kernel ramdisk support  
2797 6493 d 13 h jermar /trunk/kernel/ Each architecture should only announce its endianity.
The conversion macros should be defined only once.		  
2445 6800 d 19 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)		  
2141 6866 d 10 h jermar /trunk/ 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.		  
2071 6935 d 13 h jermar /trunk/ (c) versus (C)  
2063 6949 d 16 h jermar /trunk/kernel/generic/src/lib/ Call big endian byte swap function instead of little endian.  
2015 6974 d 13 h jermar /trunk/ 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.
