2015 6386 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 6389 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 6391 d 6 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2007 6394 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 6395 d 12 h decky /trunk/ update rd  
2004 6395 d 12 h decky /trunk/kernel/generic/include/ cleanup  
2002 6395 d 14 h decky /trunk/kernel/generic/ rd work  
2001 6397 d 4 h jermar /trunk/kernel/ Indentation and comment fixes.  
2000 6397 d 16 h decky /trunk/kernel/ move files to more proper locations  
1999 6397 d 17 h decky /trunk/ start RAM disk support  
1951 6434 d 9 h jermar /trunk/kernel/generic/include/mm/ Fix comma mistakenly removed in last commit.  
1950 6434 d 10 h jermar /trunk/kernel/ Indentation changes and coding style fixes in slab.c and slab.h.  
1941 6438 d 10 h decky /trunk/kernel/generic/include/ cleanup  
1935 6438 d 18 h decky /trunk/kernel/generic/include/ add function type  
1933 6439 d 6 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6439 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.		  
1927 6439 d 12 h decky /trunk/kernel/generic/include/ remove dummy definitions (which tent to lead to mysterious bugs)  
1924 6440 d 6 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 6440 d 7 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.		  
1922 6441 d 15 h jermar /trunk/kernel/ More IRQ stuff.
Modify the IRQ hash table functions to support lookup based on inr and devno.
Add method member to irq_t.
