gsync: Use copyin()/copyout() to access user memory
Depending on the architecture and setup, it may not be possible to
access user memory directly, for example, due to user mode mappings not
being accessible from kernel mode (x86 SMAP, AArch64 PAN). There are
dedicated machine-specific copyin()/copyout() routines that know how to
access user memory from the kernel; use them.
