    mm: add get_dump_page · f3e8fccd
    Hugh Dickins authored
    In preparation for the next patch, add a simple get_dump_page(addr)
    interface for the CONFIG_ELF_CORE dumpers to use, instead of calling
    get_user_pages() directly.  They're not interested in errors: they
    just want to use holes as much as possible, to save space and make
    sure that the data is aligned where the headers said it would be.
    
    Oh, and don't use that horrid DUMP_SEEK(off) macro!
