      libata: IDENTIFY backwards for drive side cable detection · 8c3c52a8
      Tejun Heo authored
      For drive side cable detection to work correctly, drives need to be
      identified backwards such that the slave device releases PDIAG- before
      the mater drive tries to detect cable type.  ata_bus_probe() was fixed
      by commit f31f0cc2 but the new EH path
      wasn't fixed.  This patch makes new EH path do IDENTIFY backwards.
      
      ata_dev_configure() for new devices are still performed master first.
      This is to keep the detection messages in forward order.

      ahci.c: walkaround for SB600 SATA internal error issue · 55a61604
      Conke Hu authored
         There is a HW issue in ATI SB600 SATA that PxSERR.E should not be
      set on some conditions, for example, when there is no media in SATA
      CD/DVD drive or media is not ready, AHCI controller fails to execute
      ATAPI commands and reports PORT_IRQ_TF_ERR, but ATI SB600 SATA
      controller sets PxSERR.E at the
      same time, which is not necessary.
          This patch is just to ignore the INTERNAL ERROR in such case.
      Without this patch, ahci error handler will report many errors as
      below:

      [libata] Disable ACPI by default; fix namespace problems · d7d0dad6
      Jeff Garzik authored
      Not yet ready to turn on ATA ACPI by default, for either PATA or SATA.
      
      Also, rename the global-scope module parameter variable 'noacpi' to
      something more libata-specific, reducing the potential for namespace
      collision.

      [PATCH] aio: remove bare user-triggerable error printk · 28defbea
      Zach Brown authored
      The user can generate console output if they cause do_mmap() to fail
      during sys_io_setup().  This was seen in a regression test that does
      exactly that by spinning calling mmap() until it gets -ENOMEM before
      calling io_setup().
      
      We don't need this printk at all, just remove it.
