1187 6627 d 16 h jermar /kernel/trunk/ Cleanup pm.c and pm.h code on ia32 and amd64.
Add before_task_runs() and before_task_runs_arch() for each architecture.
Add ia32 and amd64 code to ensure I/O Permission Bitmap update.		  
1185 6627 d 19 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1184 6627 d 19 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 6629 d 0 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.

1138 6644 d 16 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 6644 d 20 h vana /kernel/trunk/arch/ia64/include/ context_set patch in kernel for changed allocation of ia64 RSE and stack  
1124 6647 d 22 h jermar /kernel/trunk/arch/ Small changes.
Make sparc64 and ppc32 compile again.		  
1121 6648 d 12 h jermar /kernel/trunk/ Small textual changes.  
1108 6649 d 11 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
1107 6649 d 11 h jermar /kernel/trunk/ Small atomic #include and typedef changes.  
1106 6649 d 11 h jermar /kernel/trunk/arch/ Pass either -DCONFIG_PAGE_PT or -DCONFIG_PAGE_HT to the compiler.  
1104 6649 d 16 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.		  
1080 6654 d 15 h jermar /kernel/trunk/arch/ia64/src/mm/ Fix double page_table_unlock() in ia64 tlb.c.  
1078 6654 d 15 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.		  
1070 6654 d 23 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1066 6655 d 8 h jermar /kernel/trunk/ Support for user space threads.  
1059 6655 d 13 h jermar /kernel/trunk/ Clear user address space when creating new page tables.
Fix mapping of l_apic and io_apic on amd64.		  
1056 6655 d 15 h jermar /kernel/trunk/arch/ia64/src/ Slightly optimized version of ivt.S.  
1053 6655 d 16 h vana /kernel/trunk/ Itanium FPU Lazy context switching... but not so much tested  
1044 6655 d 20 h jermar /kernel/trunk/ Page table locking.

993 6657 d 13 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.
