You're right, it can be found at least in MIPS and amd64.

The idiom is a bit different in amd64: the variable in the for-loop =
isn't immediately reused, but it's a global variable anyway...  That's =
what I thought deserves a comment.

Regarding the pmap_kenter_temporary(), the first problem is the function =
name: it might be a temporary mapping, but the real use is for crash =
dumps (I wonder why ACPI abuses this mapping).  The other problem is the =
fact that a pmap function is so tied to crash dumps.  However, that's a =
bigger problem.
