1290 6596 d 5 h vana /kernel/trunk/arch/ VESA detection failure fix.

(Some headers)		  
1288 6596 d 7 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.		  
1265 6600 d 6 h jermar /kernel/trunk/arch/ Add dummy IRQ_COUNT and irq_ipc_bind_arch() to ia64, ppc32 and sparc64 so that they compile again.  
1210 6610 d 6 h vana /kernel/trunk/ Incomplete VHPT walker support for Itanium  
1185 6618 d 5 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1184 6618 d 5 h jermar /kernel/trunk/ Move arch/thread.h to arch/proc/thread.h on all architectures.
Replace ARCH_THREAD_DATA with new thread_arch_t arch on all architectures.
Similarily, add task_arch_t arch on all architectures.
On amd64 and ia32, grow the TSS segment by 64K + 1B to support IO port
permission bitmap. For the same reason, define per task IO port permission bitmaps
on ia32 and amd64.		  
1171 6619 d 11 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.		  
1170 6620 d 3 h vana /kernel/trunk/ Stack size definition macro definition fix  
1138 6635 d 2 h jermar /kernel/trunk/ CPU stacks must have two frames on ia64.
Make sure both thread stack frames are mapped in before_thread_runs_arch().
Take STACK_FRAMES into account during kernel memory layout initialization in main_bsp().		  
1137 6635 d 6 h vana /kernel/trunk/arch/ia64/include/ context_set patch in kernel for changed allocation of ia64 RSE and stack  
1124 6638 d 8 h jermar /kernel/trunk/arch/ Small changes.
Make sparc64 and ppc32 compile again.		  
1108 6639 d 21 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
1107 6639 d 21 h jermar /kernel/trunk/ Small atomic #include and typedef changes.  
1104 6640 d 2 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.		  
1078 6645 d 1 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.		  
1070 6645 d 9 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1053 6646 d 2 h vana /kernel/trunk/ Itanium FPU Lazy context switching... but not so much tested  
1024 6647 d 0 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1023 6647 d 1 h vana /kernel/trunk/ Itanium FPU active context switch  
993 6647 d 23 h jermar /kernel/trunk/arch/ia64/ Fix bug in switch to userspace on ia64: ensure start in bank 1.
Fix bug in tlb_invalidate_all() that cause interrupts to be unconditionally enabled.
Optimize context switching by discarding packed attribute of context structures.
