2170 6310 d 23 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2142 6314 d 6 h jermar /trunk/kernel/generic/include/mm/ Remove out of date comment.  
2126 6358 d 23 h decky /trunk/kernel/ small cleanup, more work coming  
2125 6359 d 1 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2124 6359 d 3 h decky /trunk/kernel/generic/ implement simple realloc()  
2122 6365 d 6 h decky /trunk/kernel/generic/ explicit typecast, fix signed/unsigned comparison  
2107 6367 d 0 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 6367 d 8 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 6372 d 4 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2093 6372 d 4 h decky /trunk/kernel/ spinlock extern declaration macro  
2089 6373 d 8 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2085 6379 d 7 h decky /trunk/kernel/ typedef elimination  
2083 6379 d 8 h decky /trunk/kernel/ typedef elimination  
2071 6384 d 1 h jermar /trunk/ (c) versus (C)  
2059 6407 d 10 h jermar /trunk/kernel/generic/ Improve indentation and formatting.  
2015 6423 d 1 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 6428 d 0 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2007 6430 d 23 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 6433 d 22 h jermar /trunk/kernel/ Indentation and comment fixes.  
2000 6434 d 10 h decky /trunk/kernel/ move files to more proper locations
