[libata] replace sata_settings with devslp_timing

2013-01-14T18:29:15Z

NCQ capability was used to check availability of SATA Settings page from Identify Device Data Log, which contains DevSlp timing variables. It does not work on some HDDs and leads to error messages. IDENTIFY word 78 bit 5(Hardware Feature Control) can't work either because it is only the sufficient condition of Identify Device data log, not the necessary condition. This patch replaced ata_device->sata_settings with ->devslp_timing to only save DevSlp timing variables(8 bytes), instead of the whole SATA Settings page(512 bytes).

Drivers: ata: remove __dev* attributes.

2013-01-03T23:57:03Z

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

Pull MIPS updates from Ralf Baechle: "The MIPS bits for 3.8. This also includes a bunch fixes that were sitting in the linux-mips.org git tree for a long time. This pull request contains updates to several OCTEON drivers and the board support code for BCM47XX, BCM63XX, XLP, XLR, XLS, lantiq, Loongson1B, updates to the SSB bus support, MIPS kexec code and adds support for kdump. When pulling this, there are two expected merge conflicts in include/linux/bcma/bcma_driver_chipcommon.h which are trivial to resolve, just remove the conflict markers and keep both alternatives." * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (90 commits) MIPS: PMC-Sierra Yosemite: Remove support.
