2471 6157 d 3 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)		  
2449 6172 d 13 h decky /trunk/uspace/rd/ remove unnecessary includes  
2445 6173 d 8 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)		  
2141 6238 d 23 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 6308 d 2 h jermar /trunk/ (c) versus (C)  
2015 6347 d 2 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.		  
2012 6350 d 0 h jermar /trunk/ Eliminate confusion between SYS_MAP_PHYSMEM and sys_physmem_map.
The syscall is to be called SYS_PHYSMEM_MAP from now on and the functions that participate in its implementation are
called *physmem_map().		  
2005 6356 d 7 h decky /trunk/ update rd  
1999 6358 d 11 h decky /trunk/ start RAM disk support
