+
+  Add %fs/%gs to trap frame and save/restore them on trap/interupt/
+  syscall entry from userspace.
+
+  Remove special-case ``by hand'' validation of %fs/%gs register
+  values s well as special handling of them in various signal
+  handling paths.  Now, like %ds and %es, they are validated by
+  the hardware on return to userland.
+
+  This paves the way for the use of %fs for per-cpu data on multi-
+  processor systems, and fixes an otherwise difficult-to-fix
+  interaction between threads/clone(2) and USER_LDT.
