Otherwise, the state of a reservation's pages' flags and its population count can be inconsistent. That could result in a page being freed twice. (This change should have been included in the MFC of the superpages support.)

(In retrospect, this change should have been included in the superpages MFC. This change subsumes r189750.) Discussed with: jhb 2009-03-12T22:01:42Z John Baldwin jhb@FreeBSD.org 2009-03-12T22:01:42Z urn:sha1:6fcaa123e6654a4ff1704c7c1269c7018bcde991 platforms with superpages currently because the pages used by vm_reserv_startup() are incorrectly included in the 'npages' count. I haven't removed the assertion as I think this is a real bug, but the side effect is just that some memory is wasted on never-used vm_page structures. The assertion was removed from HEAD which is why the bug wasn't noticed there (and thus this is a direct commit to 7). 2009-03-10T19:33:50Z John Baldwin jhb@FreeBSD.org 2009-03-10T19:33:50Z urn:sha1:7f307a7ee8bd205f347128834017f3667adcde0b following nodes as MPSAFE: - All standalone INT/LONG sysctls. - kern.proc.* - All name-cache related sysctls. - vm.loadavg - vm.vmtotal - vm.stats.(sys|vm).* - sysctl.name2oid - kern.ident, kern.osrelease, kern.version, etc. - kern.arandom - security.jail.jailed - kern.devname Other changes: - Remove GIANT_REQUIRED from vmtotal(). - Add conditional Giant locking around the vrele() in sysctl_kern_proc_pathname(). 2009-02-26T15:59:22Z John Baldwin jhb@FreeBSD.org 2009-02-26T15:59:22Z urn:sha1:15826f991ff92f0afe64311327d5a2f38aae5cbf superpage reservation system to the machine-independent VM system as well as changes to the pmap code for amd64 and i386 to support superpages.
