Greetings,
My understanding is that it is used to accomodate PCI memory mappings. The layout is regular memory, then PCI devices, APICs and flash, then any physical ram above remap_high goes over the 4Gig mark (for PAE).

In this file there is a variable called remap_high. I assume the function of this is to remap the high memory (512MB) so it is contiguous with the low 512MB.
Even when remap_high is true, on -current, I end up with two 512MB segemnts, one at 0 and one at 4 GB.
Anybody have any idea as to why this would happen? It's confusing 2.4.19 from what I can see.
