Add full support for these functions on amd64 and i386 and stubs for them on the other architectures. The function pmap_page_set_memattr() is also responsible for any other machine-dependent aspects of changing a page's memory attributes, such as flushing the cache or updating the direct map. The uses include kmem_alloc_contig(), vm_page_alloc(), and the device pager: kmem_alloc_contig() can now be used to allocate kernel memory with non-default memory attributes on amd64 and i386. vm_page_alloc() and the device pager will set the memory attributes for the real or fictitious page according to the object's default memory attributes. - Update the various pmap functions on amd64 and i386 that map pages to incorporate each page's memory attributes in the mapping.

This also includes changes to the ia64 machine check code to defer adding machine check records to the sysctl tree, removing Giant from the CAM code that created dynamic sysctls, and tweaking the teardown of da(4) and cd(4) peripheral devices to not hold locks when freeing the sysctl tree. 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.
