Mateusz Guzik 1dbf52e7d9 Reduce traffic on vm_cnt.v_free_count ... The variable is modified with the highly contended page free queue lock. It unnecessarily shares a cacheline with purely read-only fields and is re-read after the lock is dropped in the page allocation code making the hold time longer. Pad the variable just like the others and store the value as found with the lock held instead of re-reading. Provides a modest 1%-ish speed up in concurrent page faults.
