2619 6014 d 22 h jermar /trunk/ Modify ipc_answer_*() to make use of all six syscall arguments. The recommended
means of answering calls is via the ipc_answer_m() macros (where m denotes the
number of return arguments) that automatically decide between the fast register
version or the slow universal version of ipc_answer().		  
2518 6083 d 23 h jermar /trunk/uspace/ One occurrence of the left-over term 'pseudo thread' replaced with 'fibril' in
the rd task.

Start the vfs task. Now it is dummy, but integrated into the sources.		  
2479 6165 d 6 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2478 6167 d 2 h jermar /trunk/uspace/rd/ Add sanity checks for reads and writes that occur past the end of the
ramdisk image.		  
2475 6167 d 22 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 6171 d 0 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)		  
2449 6186 d 10 h decky /trunk/uspace/rd/ remove unnecessary includes  
2445 6187 d 5 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)		  
2141 6252 d 20 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 6321 d 23 h jermar /trunk/ (c) versus (C)  
2015 6360 d 23 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 6363 d 21 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 6370 d 4 h decky /trunk/ update rd  
1999 6372 d 8 h decky /trunk/ start RAM disk support
