Bjorn Helgaas 6d40fc514c [IA64] fail mmaps that span areas with incompatible attributes ... Example memory map (from HP sx1000 with VGA enabled): 0x00000 - 0x9FFFF supports only WB (cacheable) access 0xA0000 - 0xBFFFF supports only UC (uncacheable) access 0xC0000 - 0xFFFFF supports only WB (cacheable) access Some versions of X map the entire 0x00000-0xFFFFF area at once. With the example above, this mmap must fail because there's no memory attribute that's safe for the entire area. Prior to this patch, we performed the mmap with a UC mapping. When X accessed the WB memory at 0xC0000, it caused an MCA. The crash can happen when mapping 0xC0000 from either /dev/mem or a /sys/.../legacy_mem file.
