2019 6401 d 22 h decky /trunk/kernel/ prepare for new test infrastructure  
2015 6403 d 20 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 6406 d 18 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 6408 d 19 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2007 6411 d 18 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 6413 d 0 h decky /trunk/ update rd  
2004 6413 d 0 h decky /trunk/kernel/generic/include/ cleanup  
2002 6413 d 2 h decky /trunk/kernel/generic/ rd work  
2001 6414 d 17 h jermar /trunk/kernel/ Indentation and comment fixes.  
2000 6415 d 5 h decky /trunk/kernel/ move files to more proper locations  
1999 6415 d 5 h decky /trunk/ start RAM disk support  
1951 6451 d 22 h jermar /trunk/kernel/generic/include/mm/ Fix comma mistakenly removed in last commit.  
1950 6451 d 22 h jermar /trunk/kernel/ Indentation changes and coding style fixes in slab.c and slab.h.  
1941 6455 d 23 h decky /trunk/kernel/generic/include/ cleanup  
1935 6456 d 6 h decky /trunk/kernel/generic/include/ add function type  
1933 6456 d 19 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6456 d 20 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.		  
1927 6457 d 1 h decky /trunk/kernel/generic/include/ remove dummy definitions (which tent to lead to mysterious bugs)  
1924 6457 d 19 h jermar /trunk/kernel/generic/ For the sake of clarity, get rid of negative INR for virtual interrupts.
This way, the code can hurt performance on systems where the non-negative klog INR overlaps
with a frequently used INR such as system clock on amd64 and ia32.		  
1923 6457 d 19 h jermar /trunk/ Replace the old IRQ dispatcher and IPC notifier with new implementation.
Note that all architectures except for sparc64 are now broken
and don't even compile.
