After commit 464d1a78fbf8cf6c7fd970e7b3e2db50a320ce28 aka "[PATCH] i386: Convert i386 PDA code to use %fs" %fs saved during context switch moved from thread_struct to pt_regs.
Ifdef out it on i386. I don't understand why .fs (OK, .gs first) initializer was added, kernel clearly stopped touching it after the patch.
