sparse warns about incorrect type when using __be64 data.
It is not being converted to CPU-endian but it should be.
Fixes these sparse warnings:
../block/sed-opal.c:375:20: warning: incorrect type in assignment (different base types)
../block/sed-opal.c:375:20: expected unsigned long long [usertype] align
../block/sed-opal.c:375:20: got restricted __be64 const [usertype] alignment_granularity
../block/sed-opal.c:376:25: warning: incorrect type in assignment (different base types)
../block/sed-opal.c:376:25: expected unsigned long long [usertype] lowest_lba
../block/sed-opal.c:376:25: got restricted __be64 const [usertype] lowest_aligned_lba
Fixes: 455a7b238cd6 ("block: Add Sed-opal library")

This is a generic implementation of gettimeofday vdso.

Defines the cross-compiler prefix for compiling compat vDSO.
If a 64 bit compiler (i.e. x86_64) can compile the VDSO for
32 bit, it does not need to define this parameter.
