+Subject: [PATCH 1/3] ahci: Annotate PCI ids for mobile Intel chipsets as such
+
+Intel uses different SATA PCI ids for the Desktop and Mobile SKUs of their
+chipsets. For older models the comment describing which chipset the PCI id
+is for, aksi indicates when we're dealing with a mobile SKU. Extend the
+comments for recent chipsets to also indicate mobile SKUs.
+
+The information this commit adds comes from Intel's chipset datasheets.
+
+This commit is a preparation patch for allowing a different default
+sata link powermanagement policy for mobile chipsets.

+Subject: [PATCH 3/3] ahci: Allow setting a default LPM policy for mobile
+ chipsets
+
+On many laptops setting a different LPM policy then unknown /
+max_performance can lead to power-savings of 1.0 - 1.5 Watts (when idle).
+
+Modern ultrabooks idle around 6W (at 50% screen brightness), 1.0 - 1.5W
+is a significant chunk of this.
+
+There are some performance / latency costs to enabling LPM by default,
+so it is desirable to make it possible to set a different LPM policy
+for mobile / laptop variants of chipsets / "South Bridges" vs their
+desktop / server counterparts. Also enabling LPM by default is not
+entirely without risk of regressions. At least min_power is known to
+cause issues with some disks, including some reports of data corruption.
+
+This commits adds a new ahci.mobile_lpm_policy kernel cmdline option,
+which defaults to a new SATA_MOBILE_LPM_POLICY Kconfig option so that
+Linux distributions can choose to set a LPM policy for mobile chipsets
+by default.
+
+The reason to have both a kernel cmdline option and a Kconfig default
+value for it, is to allow easy overriding of the default to allow
+trouble-shooting without needing to rebuild the kernel.
