Thanks for catching this. This is required because on some
architectures, flush_tlb_range have non void returns. For example on
parisc we have
int __flush_tlb_range(unsigned long sid,
unsigned long start, unsigned long end);
#define flush_tlb_range(vma, start, end) \
__flush_tlb_range((vma)->vm_mm->context, start, end)
