    compat: Add helper functions to read/write struct timeval, timespec · 6684ba20
    H. Peter Anvin authored
    Add helper functions to read and write struct timeval and struct
    timespec from userspace.  We already had helper functions for reading
    and writing struct compat_timespec; add a set of functions to do the
    same with struct timeval, and add a second suite of functions which
    can be sensitive to COMPAT_USE_64BIT_TIME and access either 32- or
    64-bit time structures.
    
    This also exports these helper functions to modules.
    
    Rename the existing inlines for converting between struct
    compat_timeval and native struct timespec so we can have a saner
    naming convention for the exported functions.
