Adds a new function, persistent_ram_early_init, designed to be called from the machine init_early callback, that calls memblock_remove and saves the provided persistent ram area layout. Drivers only pass in their struct device * and ecc settings. Locating and mapping the memory is now handled entirely within persistent_ram. Also, convert ram_console to the new persistent_ram_init parameters that only take a struct device * and ecc settings. [jstultz: Fix pr_info casting issues on 64bit, folded two patches as the build breaks if they are apart. Also replaced phys_to_page() w/ pfn_to_page(addr>>PAGE_SHIFT), as phys_to_page is only on a few arches.] CC: Greg KH CC: Android Kernel Team Signed-off-by: Colin Cross Signed-off-by: John Stultz Signed-off-by: Greg Kroah-Hartman --- Reading git-diff-tree failed
