[PATCH 08/30] i386: ifdef out struct thread_struct::fs

[Alexey Dobriyan]

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.
