2015 6410 d 7 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 6413 d 5 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().
 
2009 6415 d 6 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2007 6418 d 5 h jermar /trunk/kernel/ Introduce page colors. So far, only sparc64 uses correct page color bits. Other architectures have a dummy define
specifying zero bits for a page color.

There is a new check of page color in as_area_share(). Because of lack of support for this in the userspace, the
check has been #ifef'ed out.
 
2005 6419 d 12 h decky /trunk/ update rd  
2004 6419 d 12 h decky /trunk/kernel/generic/include/ cleanup  
2002 6419 d 14 h decky /trunk/kernel/generic/ rd work  
2001 6421 d 4 h jermar /trunk/kernel/ Indentation and comment fixes.  
2000 6421 d 16 h decky /trunk/kernel/ move files to more proper locations  
1999 6421 d 17 h decky /trunk/ start RAM disk support  
1981 6431 d 15 h jermar /trunk/kernel/ Indentation, formatting and minor changes.  
1972 6444 d 14 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.
 
1954 6454 d 6 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.
 
1951 6458 d 9 h jermar /trunk/kernel/generic/include/mm/ Fix comma mistakenly removed in last commit.  
1950 6458 d 10 h jermar /trunk/kernel/ Indentation changes and coding style fixes in slab.c and slab.h.  
1941 6462 d 10 h decky /trunk/kernel/generic/include/ cleanup  
1935 6462 d 18 h decky /trunk/kernel/generic/include/ add function type  
1933 6463 d 6 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6463 d 7 h jermar /trunk/kernel/ Do not copy notification config out of the IRQ structure.
Add the notify member, that toggles notifications on and off instead.
This is good for preventing other tasks from registering the notification
while the notification config is stored outside the IRQ structure.
It should also help to implement the cleanup code.
 
1929 6463 d 12 h decky /trunk/kernel/generic/src/console/ ipc_irq_send_msg(NULL, 0, 0, 0) is definitively a bug
