Subject: [PATCH for review] [18/48] x86_64: flush_tlb_kernel_range() warning fix


From: Andrew Morton <akpm@...ux-foundation.org>

mm/vmalloc.c: In function 'unmap_kernel_range':
mm/vmalloc.c:75: warning: unused variable 'start'

make it a C function so that the compiler thinks it used its arguments.
