parisc: sticon - unbreak on 64bit kernel
STI text console (sticon) was broken on 64bit machines with more than 4GB RAM and this lead in some cases to a kernel crash. Since sticon uses the 32bit STI API it needs to keep pointers to memory below 4GB. But on a 64bit kernel some memory regions (e.g. the kernel stack) might be above 4GB which then may crash the kernel in the STI functions. Additionally sticon didn't selected the built-in framebuffer fonts by default. This is now fixed. On a side-note: Theoretically we could enhance the sticon driver to use the 64bit STI API. But - beside the fact that some machines don't provide a 64bit STI ROM - this would just add complexity. Signed-off-by: Helge Deller <deller@gmx.de> Cc: stable@vger.kernel.org # 3.8+
