x86, 32-bit: ifdef out struct thread_struct::fs
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 and value on thread_struct became unused. [ Impact: reduce thread_struct size on 32-bit ] Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Cc: containers@lists.linux-foundation.org LKML-Reference: <20090503232952.GI16631@x200.localdomain> Signed-off-by: Ingo Molnar <mingo@elte.hu>
