H A D | spapr_hcall.c | d76ab5e1 Tue Sep 20 11:35:01 CDT 2016 Nikunj A Dadhania <nikunj@linux.vnet.ibm.com> target-ppc: tlbie/tlbivax should have global effect tlbie (BookS) and tlbivax (BookE) plus the H_CALLs(pseries) should have a global effect. Introduces TLB_NEED_GLOBAL_FLUSH flag. During lazy tlb flush, after taking care of pending local flushes, check broadcast flush(at context synchronizing event ptesync/tlbsync, etc) is needed. Depending on the bitmask state of the tlb_need_flush, tlb is flushed from other cpus if needed and the flags are cleared.
