[Qemu-devel] [PATCH for-2.3 0/4] ahci: fix big endian PIO failures

[John Snow <jsnow@redhat.com>]

Two issues were unearthed from ahci-test on ppc64:

(1) The ahci_populate_sglist function had endian issues,
    which is only likely to impact PIO transfers for buffers
    greater than one sector, and

(2) multiple-sector PIO which I attempted to repair in
    36334faf has been broken for years. ahci-test didn't catch
    this because it used a pattern that was identical for each
    sector.

    So the pattern has been corrected and the underlying issue
    fixed.

This should clear up the test failures (properly) for ppc64.
