subr_pctrie: use ilog2(x) instead of fls(x)-1 In three instances where fls(x)-1 is used, the compiler does not know that x is nonzero and so adds needless zero checks. Using ilog(x) instead saves, in each instance, about 4 instructions, including a conditional, and 16 or so bytes, on an amd64 build.

vm_phys: Try to clean up NUMA KPIs It can useful for code outside the VM system to look up the NUMA domain of a page backing a virtual or physical address, specifically when creating NUMA-aware data structures. We have _vm_phys_domain() for this, but the leading underscore implies that it's an internal function, and vm_phys.h has dependencies on a number of other headers. Rename vm_phys_domain() to vm_page_domain(), and _vm_phys_domain() to vm_phys_domain(). Make the latter an inline function. Add _vm_phys.h and define struct vm_phys_seg there so that it's easier to use in other headers. Include it from vm_page.h so that vm_page_domain() can be defined there. Include machine/vmparam.h from _vm_phys.h since it depends directly on some constants defined there.
