2129 6336 d 18 h jermar /trunk/ Fix small problem in sparc64 port.

Bump version to 0.2.0.4 (Sunset).		  
2128 6343 d 20 h jermar /trunk/ Add arm32 architecture. The 32 suffix is used to specify that 16-bit Thumb
instructions are not used. The arm32 code is mostly composed of placeholders
that need to be replaced by real implementation. So far, the arm32 tree
only compiles. If run under GXEmul simulator, an infinit loop at the
kernel entry point will be entered.		  
2125 6344 d 19 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2110 6351 d 18 h jermar /trunk/kernel/arch/ia64/ Minor cleanup in ia64.  
2107 6352 d 17 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 6353 d 2 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.		  
2105 6357 d 2 h decky /trunk/kernel/ move ipc structures to ipc.h  
2101 6357 d 20 h decky /trunk/kernel/ fix signed/unsigned comparison and integer overflow  
2100 6357 d 20 h decky /trunk/kernel/ signed/unsigned comparison, explicit typecast  
2099 6357 d 21 h decky /trunk/kernel/arch/ia32/src/ explicit cast on pointer arithmetic  
2097 6357 d 21 h decky /trunk/kernel/arch/ia32/src/smp/ fix signed/unsigned comparison  
2095 6357 d 21 h decky /trunk/kernel/arch/ia32/src/smp/ fix signed/unsigned comparison  
2091 6358 d 21 h jermar /trunk/kernel/arch/sparc64/src/ Fix creating the kkbdpoll() kernel thread on sparc64 SMP machines.
This fixes Ticket #19.		  
2089 6359 d 1 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2087 6359 d 21 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2083 6365 d 1 h decky /trunk/kernel/ typedef elimination  
2082 6365 d 2 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2079 6365 d 20 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2078 6365 d 22 h jermar /trunk/kernel/arch/sparc64/src/ When invalidating entire TLBs on sparc64, make sure to also invalidate any (locked) global entries.
This fixes Ticket #21.
Fix a comment in start.S stating that the kernel installs a global entry for itself. All entries installed by the kernel
are local to some memory context.		  
2076 6368 d 3 h jermar /trunk/kernel/ Beat the implicit illegal virtual alias created by reusing userspace frames.
In the anonymous and ELF backends, if the architecture has virtually indexed D-cache,
selectively flush cachelines belonging to the frame being freed.
This fixes Ticket #20.
