[ Upstream commit 6aa676761d4c1acfa31320e55fa1f83f3fcbbc7a ]
Commit:
c5bedc6847c3b ("x86/fpu: Get rid of PF_USED_MATH usage, convert it to fpu->fpstate_active")
introduced the 'fpu' variable at top of __restore_xstate_sig(), which now shadows the other definition:
arch/x86/kernel/fpu/signal.c:318:28: warning: symbol 'fpu' shadows an earlier one arch/x86/kernel/fpu/signal.c:271:20: originally declared here
Remove the shadowed definition of 'fpu', as the two definitions are the same.
