2015 6416 d 21 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.		  
2014 6418 d 23 h decky /trunk/ version bump to Xen 3.0.3 (not fully operational yet)  
2012 6419 d 19 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().		  
2011 6421 d 1 h decky /trunk/kernel/ resolve ticket #4  
2010 6421 d 20 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix comment.  
2009 6421 d 20 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6423 d 21 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2007 6424 d 19 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 6426 d 2 h decky /trunk/ update rd  
2004 6426 d 2 h decky /trunk/kernel/generic/include/ cleanup  
2003 6426 d 2 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
2002 6426 d 4 h decky /trunk/kernel/generic/ rd work  
2001 6427 d 19 h jermar /trunk/kernel/ Indentation and comment fixes.  
2000 6428 d 7 h decky /trunk/kernel/ move files to more proper locations  
1999 6428 d 7 h decky /trunk/ start RAM disk support  
1996 6433 d 23 h jermar /trunk/kernel/ Add option to compile the sparc64 kernel without the TTE_CV bit support.
The bit is not used by default now.
Enabling it may theoretically lead to physical memory inconsistencies until code that
mitigates the problem is written.		  
1995 6433 d 23 h jermar /trunk/kernel/ Move general configuration out of debugging configuration.
Add CONFIG_VIRT_IDX_CACHE.		  
1994 6434 d 4 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6434 d 5 h decky /trunk/ make framebuffer code more generic  
1991 6434 d 22 h jermar /trunk/kernel/genarch/src/fb/ The prefered switch statement indentation is the one replaced by the previous commit :-)
