2170 6272 d 2 h jermar /trunk/kernel/ Simplify synchronization in as_switch().
The function was oversynchronized, which
was causing deadlocks on the address
space mutex.

Now, address spaces can only be switched
when the asidlock is held. This also protects
stealing of ASIDs. No other synchronization
is necessary.		  
2142 6275 d 9 h jermar /trunk/kernel/generic/include/mm/ Remove out of date comment.  
2126 6320 d 2 h decky /trunk/kernel/ small cleanup, more work coming  
2125 6320 d 4 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2124 6320 d 6 h decky /trunk/kernel/generic/ implement simple realloc()  
2122 6326 d 9 h decky /trunk/kernel/generic/ explicit typecast, fix signed/unsigned comparison  
2107 6328 d 3 h jermar /trunk/ When clock() is called by an external interrupt dispatched by the IRQ dispatcher,
no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24.

Formating and indentation fixes.		  
2106 6328 d 11 h jermar /trunk/kernel/ Merge as_t structure into one and leave the differring parts in as_genarch_t.

Indentation and formatting changes in header files.		  
2094 6333 d 7 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2093 6333 d 7 h decky /trunk/kernel/ spinlock extern declaration macro  
2089 6334 d 11 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2085 6340 d 10 h decky /trunk/kernel/ typedef elimination  
2083 6340 d 11 h decky /trunk/kernel/ typedef elimination  
2071 6345 d 4 h jermar /trunk/ (c) versus (C)  
2059 6368 d 13 h jermar /trunk/kernel/generic/ Improve indentation and formatting.  
2015 6384 d 4 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.		  
2009 6389 d 3 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2007 6392 d 2 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.		  
2001 6395 d 1 h jermar /trunk/kernel/ Indentation and comment fixes.  
2000 6395 d 13 h decky /trunk/kernel/ move files to more proper locations
