[PATCH 4.19 254/639] x86/mm: Remove unused variable cpu

[Greg Kroah-Hartman]

From: Qian Cai <cai@xxxxxx>

[ Upstream commit 3609e31bc8dc03b701390f79c74fc7fe92b95039 ]

The commit a2055abe9c67 ("x86/mm: Pass flush_tlb_info to
flush_tlb_others() etc") removed the unnecessary cpu parameter from
uv_flush_tlb_others() but left an unused variable.

arch/x86/mm/tlb.c: In function 'native_flush_tlb_others':
arch/x86/mm/tlb.c:688:16: warning: variable 'cpu' set but not used
[-Wunused-but-set-variable]
   unsigned int cpu;
                ^~~
