seqcount: Provide raw_read_seqcount()
raw_read_seqcount opens a read critical section of the given seqcount
without any lockdep checking and without checking or masking the
LSB. Calling code is responsible for handling that.
Preparatory patch to provide a NMI safe clock monotonic accessor
function.
