2170 6400 d 19 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2142 6404 d 2 h jermar /trunk/kernel/generic/include/mm/ Remove out of date comment.  
2126 6448 d 19 h decky /trunk/kernel/ small cleanup, more work coming  
2125 6448 d 21 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2124 6448 d 23 h decky /trunk/kernel/generic/ implement simple realloc()  
2122 6455 d 2 h decky /trunk/kernel/generic/ explicit typecast, fix signed/unsigned comparison  
2107 6456 d 20 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 6457 d 4 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 6462 d 0 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2093 6462 d 0 h decky /trunk/kernel/ spinlock extern declaration macro  
2089 6463 d 4 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2085 6469 d 3 h decky /trunk/kernel/ typedef elimination  
2083 6469 d 4 h decky /trunk/kernel/ typedef elimination  
2071 6473 d 21 h jermar /trunk/ (c) versus (C)  
2059 6497 d 6 h jermar /trunk/kernel/generic/ Improve indentation and formatting.  
2015 6512 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.		  
2009 6517 d 20 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2007 6520 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.		  
2001 6523 d 18 h jermar /trunk/kernel/ Indentation and comment fixes.  
2000 6524 d 6 h decky /trunk/kernel/ move files to more proper locations
