    x86/mm: Relocate page fault error codes to traps.h · 1067f030
    Ricardo Neri authored
    Up to this point, only fault.c used the definitions of the page fault error
    codes. Thus, it made sense to keep them within such file. Other portions of
    code might be interested in those definitions too. For instance, the User-
    Mode Instruction Prevention emulation code will use such definitions to
    emulate a page fault when it is unable to successfully copy the results
    of the emulated instructions to user space.
    
    While relocating the error code enumeration, the prefix X86_ is used to
    make it consistent with the rest of the definitions in traps.h. Of course,
    code using the enumeration had to be updated as well. No functional changes
    were performed.
