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

2015-03-19 Thread John Snow
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.
