There were a lot of unnecessary patches, such as the VRAM patches; as Nicholas Chin has explained to me, the drivers for these machines will just allocate what RAM they want anyway, so in a lot of cases the extra allocated Video RAM simply reduces the total amount of memory for other uses. In general, we have a lot of patches that have existed for years. A much more aggressive sweep will be done in the next major audit, especially when the revisions are updated again.

Subject: [PATCH 02/51] lenovo/t400: Enable all SATA ports
|
|
|
|
There are 2 SATA ports on the chassis of t400(s), but at least one dock for
|
|
t400 contains a port for (P/S)ATA device, and t400s has a eSATA port on its
|
|
chassis, and another one on its dock.
|
|
|
|
They have to be unmasked via device tree to use.
|
|
|
|
This patch unmasked all SATA ports found within t400s with factory firmware.
