CVE-2014-3879: Incorrect error handling in PAM policy parser:
Missing module files were treated as soft failures leading to
unexpected behavior if policy files were copied between hosts with
differently installed modules or in the short period during upgrades
when module files were being replaced.
For consistency, handle REQUISITE modules the same way as we handle REQUIRED
and BINDING.
Provide sysctl for namecache statistics.
Regen.
Use vm.uvmexp data as much as possible for vmstat -s.
Temporarily disable shadowing warning until the other users are cleaned
up.
Convert the remaining uvmexp users to the sysctl as default source.
Use kern.clockrate if possible.
Use CPU statistics from uvmexp when possible.
GC left-over kread.
Always use_sysctl in preparation of removing all kvm code.
Fix tpyo.
Add some peepholes to help pushing of adjacent registers or memory locations
on the stack.  Add a peephole to translate two pushes on integers into
one push of a DImode register.
Patch from Nobuyoshi SATO: scale secondary cpu frequency in attach message
just like the primary one.
Remove comment about possible identification of the MCUCTL
