I'm confused. How did we end up with a 64-bit PFN number on ARM? It's insane - especially as the kernel uses "unsigned long" almost everywhere for PFNs - we can't have physical addresses more than 44 bits (32 bit pfn + 4k page size). > Suggested by Andrew Cooper on lkml message > <5569F9C9.8000607@citrix.com>. > > The ifdef for ARM is ugly but did not find better solutions for it. #ifdef __arm__ maybe? Even if not, the unsightly parens are not necessary. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net.
