+    target/i386/tcg: use X86Access for TSS access
+    
+    This takes care of probing the vaddr range in advance, and is also faster
+    because it avoids repeated TLB lookups.  It also matches the Intel manual
+    better, as it says "Checks that the current (old) TSS, new TSS, and all
+    segment descriptors used in the task switch are paged into system memory";
+    note however that it's not clear how the processor checks for segment
+    descriptors, and this check is not included in the AMD manual.
