X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=de338a3795bbcb3c3d77591f65118cbec776cc39;p=linux-beck.git [S390] Fix vmalloc area size calculation. setup_memory_end() uses VMALLOC_END instead of VMALLOC_END_INIT to calculate the maximum supported size of physical memory. Since VMALLOC_END is zero, this will cause a crash on 31 bit systems.
