That's not true.  We talked about your "map=" proposal at length back
in September.  You concluded "That the discovery should be elsewhere
in an ARCH/driver LLD and pmem stays generic." [1].  A generic
approach is being specified by the ACPI Working Group and will be
released "Real Soon Now (TM)" (on the order of weeks not months).  My
first choice would be to finish waiting for that specification before
we upstream a pmem driver.  Outside of that, if we need a pmem driver
"now", Ross's version has the nice property of having an easier to
revert resource discovery mechanism.  The kernel command line is
arguably an ABI and the need for "map=" is obviated by a generic
resource discovery mechanism.
