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.
