2478 6154 d 16 h jermar /trunk/uspace/rd/ Add sanity checks for reads and writes that occur past the end of the
ramdisk image.		  
2475 6155 d 12 h jermar /trunk/uspace/rd/ Improve the rd task (not tested):
- allow more connections
- support write operation
- support concurrent requests
- sanity checks
- add comments

Please review.		  
2471 6158 d 14 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)		  
2449 6174 d 0 h decky /trunk/uspace/rd/ remove unnecessary includes  
2445 6174 d 19 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)		  
2141 6240 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 6309 d 13 h jermar /trunk/ (c) versus (C)  
2015 6348 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.		  
2012 6351 d 11 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 6357 d 18 h decky /trunk/ update rd  
1999 6359 d 22 h decky /trunk/ start RAM disk support
