John David Anglin bda079d336 parisc: use spin_lock_irqsave/spin_unlock_irqrestore for PTE updates ... User applications running on SMP kernels have long suffered from instability and random segmentation faults. This patch improves the situation although there is more work to be done. One of the problems is the various routines in pgtable.h that update page table entries use different locking mechanisms, or no lock at all (set_pte_at). This change modifies the routines to all use the same lock pa_dbit_lock. This lock is used for dirty bit updates in the interruption code. The patch also purges the TLB entries associated with the PTE to ensure that inconsistent values are not used after the page table entry is updated. The UP and SMP code are now identical. The change also includes a minor update to the purge_tlb_entries function in cache.c to improve its efficiency.
