between instructions and data wishes to capture
instruction lines in L2 with L2CTL[L2IO] = 1, it must
perform dcbst to flush the line out of the dL1 before
fetching it into L2.

L2CTL[L2IO = 0.
An icbtls_L2 that hits modified in L1 cannot be
distinguished from dcbtls_L2 and sets the L2 dlock
bit. If software shares cache lines between
instructions and data and wishes to set hillocks in
L2, it must perform dcbst to flush the line out of the
dL1 before locking it in L2.
