    xen: Introduce __initconst to store initial const data
    It's possible to have 2 type (const and non-const) of data in the same
    compilation unit. Using only __initdata will result to a compilation error:
        error: $variablename causes as section tupe conflict with $variablename2
    because a section containing const variables is marked read only and so 
    contain non-const variables.
