m68k/atari - atafb: convert allocation of fb ram to new interface
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_stram_to_phys() etc. helpers must be used to determine physical addresses. fb.fix->smem_start needs physical addresses, fb.par->screen_base needs virtual addresses. Take care of the virt-to-phys conversion both on fb init and par changes. Signed-off-by: Michael Schmitz <schmitz@debian.org> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
