[ARM] 4644/2: fix flush_kern_tlb_range() in module space
For kernel addresses between TASK_SIZE and PAGE_OFFSET, flush_tlb_kern_range() does not work as would be expected. The TLB invalidate works with a matching ASID, or on entries marked as global. The set_pte_at() macro marks addresses >= PAGE_OFFSET as global, but not addresses from TASK_SIZE to PAGE_OFFSET, which are also kernel addresses. The result is that the entries in this range are not actually invalidated by flush_tlb_kern_range(). This patch instead marks addresses >= TASK_SIZE as global.
