Marcel Moolenaar 229d894543 In pmap_set_pte(), make sure to enforce ordering by inserting a memory ... fence. Under system load, the CPU has been found to change the order by which the stores are made visible. When the tag is made visible before the other TLB values, other CPUs may use the invalid TLB values and do bad things. While here (i.e. not a fix) don't return errors from pmap_remove_vhpt() to callers of pmap_remove_pte(). Those callers don't check the return value and as such don't do what is needed to keep a consistent state. More importantly, pmap_remove_vhpt() can't really have an error without it indicating something unintended. Using KASSERT is therefore better. PR: 182999, 183227		2014-01-20 18:37:35 +00:00
