 * cifs_unicode:  Unicode kernel case support
 *
 * Function:
 *     Convert a unicode character to upper or lower case using
 *     compressed tables.

 * Notes:
 *     These APIs are based on the C library functions.  The semantics
 *     should match the C functions but with expanded size operands.
 *
 *     The upper/lower functions are based on a table created by mkupr.
 *     This is a compressed table of upper and lower case conversion.
