The D-cache flushing added here was to deal with I-cache incoherency observed on ia64. However, the problem was in the implementation of pmap_enter_object() for ia64: it was missing I-cache coherency logic for prefaulted pages. After this got added in rev 195625, testing showed that no D-cache flushing was required. The SIGILL that was observed on Book-E (see commit log for rev 192323) ended up not being related to I-cache incoherency, but was found to be caused by bad memory. This discovery further undermined the need for D-cache flushing in the NFS I/O code, triggering the reversal. Approved by: re (kensmith) |
