David S. Miller 473ad7f4fb sparc64: Fix reversed start/end in flush_tlb_kernel_range() ... When we have to split up a flush request into multiple pieces (in order to avoid the firmware range) we don't specify the arguments in the right order for the second piece. Fix the order, or else we get hangs as the code tries to flush "a lot" of entries and we get lockups like this: [ 4422.981276] NMI watchdog: BUG: soft lockup - CPU#12 stuck for 23s!
