| H A D | pmap-v4.c | diff 240803 Sat Sep 22 04:56:20 MDT 2012 alc Since UMA_ZONE_NOFREE is specified when l2zone and l2table_zone are created, there is no need to release and reacquire the pmap and pvh global locks around calls to uma_zfree(). Recursion into the pmap simply won't occur. Eliminate the use of M_USE_RESERVE. It is deprecated and, in fact, counter- productive, meaning that it actually makes the memory allocation request more likely to fail. Eliminate the macros pmap_{alloc,free}_l2_dtable(). They are of limited utility, and pmap_free_l2_dtable() was inconsistently used. Tidy up pmap_init(). In particular, change the initialization of the PV zone so that it doesn't span the initialization of the l2 and l2table zones. Tested by: jmg |
