Maybe so -- at least on the architectures that use /dev/crash, i.e., those that impose CONFIG_STRICT_DEVMEM, because the RHEL /dev/crash driver requires the pfn to get past page_is_ram(). But because page_is_ram() is not exported on non-RHEL kernels, the page_is_ram() check is commented out of the sample /dev/crash driver included in the crash source tree in the memory_driver subdirectory.
