    ARM: use __inttype() in get_user() · d09fbb32
    Russell King authored
    Borrow the x86 implementation of __inttype() to use in get_user() to
    select an integer type suitable to temporarily hold the result value.
    This is necessary to avoid propagating the volatile nature of the
    result argument, which can cause the following warning:
    
    lib/iov_iter.c:413:5: warning: optimization may eliminate reads and/or writes to register variables [-Wvolatile-register-var]
