This patchset improves ATA ACPI support as proposed in the following message. http://article.gmane.org/gmane.linux.ide/17554 Improvements are... * safe and simpler ACPI node association * major code cleanup * invoke ACPI methods only when ACPI spec says necessary * proper ACPI error handling with a retry * after successfully executing _GTF taskfiles, IDENTIFY page is reloaded * _GTM/_STM support This patchset is composed of 13 patches. #01-02 : misc preparation #03-04 : separate out ata_dev_reread_id() and make revalidation robust against size change during device configuration #05-06 : clean up libata-acpi.c #07-08 : implement ata_acpi_associate() #09-10 : more cleanups #11-13 : reimplement ACPI invocation so that methods are called where the spec specifies and errors are properly handled, and add _GTM/_STM support. Tested on three desktop boards (nf ultra, ich7 and ich8) and a notebook. This patchset is against... upstream (5365067b4bb17d1801fefe995d1342108b324471) + [1] pata_amd-remove-contamination + [2] libata-add-missing-call-to-cable_detect-in-new-EH + [3] libata-acpi-fix-GTF-command-protocol-for-ATAPI Thanks. -- tejun [1] http://article.gmane.org/gmane.linux.ide/18120 [2] http://article.gmane.org/gmane.linux.ide/18121 [3] http://article.gmane.org/gmane.linux.ide/18122
