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. -- Rui Paulo
