                     24: - return UD exception if LOCK prefix incorrectly used
                     25: - test ldt limit < 7 ?
                     26: - tests for each target CPU
                     27: - fix CCOP optimisation
                     28: - fix all remaining thread lock issues (must put TBs in a specific invalid
                     29:   state, find a solution for tb_flush()).
                     30: 
                     31: ppc specific:
                     32: ------------
                     33: - TLB invalidate not needed if msr_pr changes
                     34: - enable shift optimizations ?
                     35: 
1.1.1.2   root       36: linux-user specific:
                     37: -------------------
1.1       root       38: - add IPC syscalls
                     39: - handle rare page fault cases (in particular if page fault in helpers or
                     40:   in syscall emulation code).
                     41: - more syscalls (in particular all 64 bit ones, IPCs, fix 64 bit
                     42:   issues, fix 16 bit uid issues)
                     43: - use page_unprotect_range in every suitable syscall to handle all
                     44:   cases of self modifying code.
1.1.1.2   root       45: - fix thread stack freeing (use kernel 2.5.x CLONE_CHILD_CLEARTID)
                     46: - use kernel traps for unaligned accesses on ARM ?
                     47: 
                     48: 
                     49: lower priority:
                     50: --------------
                     51: - int15 ah=86: use better timing
                     52: - suppress shift_mem ops
                     53: - fix some 16 bit sp push/pop overflow (pusha/popa, lcall lret)
                     54: - optimize FPU operations (evaluate x87 stack pointer statically)
                     55: - use -msoft-float on ARM
