[PATCH v3 2/4] m68k/atari - atafb: convert allocation of fb ram to new interface

2014-03-31 Thread Michael Schmitz
The new atari_stram_alloc interface returns kernel virtual addresses even if the kernel runs in FastRAM. These addresses are not guaranteed to be identical with the physical addresses. Since ST-RAM mappings have not been set up by mem_init, virt_to_phys() and its cousin do not work and the atari_st
