-----Original Message----- From: Catalin Marinas [mailto:catalin.marinas at arm.com] For the time being, I would keep defconfig to 39-bit VA. If we start seeing systems with lots of RAM (over 256GB), we'll probably change the defconfig.Somone who follows the "Principles" doc "correctly" will hit an issue with the linear memory map after 32GB of RAM, right? 2 GB in 1st alias, 30 GB in 2nd alias, and rest at the 544 GB offset.
Right (though I still don't like it but, well...). -- Catalin
