2013-11-26m68k: Mark functions only called from setup_arch() __initGeert Uytterhoeven1-1/+2
Some functions that are only called (indirectly) from setup_arch() lack __init annotations. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2013-08-23m68k/atari: ARAnyM - Always use physical addresses in NatFeat callsGeert Uytterhoeven1-7/+7
Pointers passed to ARAnyM NatFeat calls should be physical addresses, not virtual addresses. This worked before because on Atari, physical and virtual kernel addresses are the same, as long as normal kernel memory is concerned. Correct the few remaining places where virtual addresses were used. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2013-08-14m68k/atari: ARAnyM - Fix NatFeat module supportGeert Uytterhoeven1-4/+19
As pointed out by Andreas Schwab, pointers passed to ARAnyM NatFeat calls should be physical addresses, not virtual addresses. Fortunately on Atari, physical and virtual kernel addresses are the same, as long as normal kernel memory is concerned, so this usually worked fine without conversion. But for modules, pointers to literal strings are located in vmalloc()ed memory. Depending on the version of ARAnyM, this causes the nf_get_id() call to just fail, or worse, crash ARAnyM itself with e.g. Gotcha! Illegal memory access. Atari PC = $968c This is a big issue for distro kernels, who want to have all drivers as loadable modules in an initrd. Add a wrapper for nf_get_id() that copies the literal to the stack to work around this issue.
