commit 669fbbf7b5b168ecb7f843bff5909f6ccd9a8f91
Author: Matthew Dillon <dillon@apollo.backplane.com>

AHCI - Add conditional logic for wcache and rahead, enhanced reporting, fixes
* Do not enable the write cache if the ident info says it is already enabled.
* Do not enable read-ahead if the ident info says it is already enabled.
* Do not try to set the freeze lock if the security feature is not supported.
* Enhanced error reporting.
* Report wcache and rahead state in the Ident.
NOTE: "WD My Book" ESATA consumer devices generate a fatal interface error
when presented with ATA_C_SET_FEATURES. The above code will quietly
work around the problem. The bug is likely in the My Book daughter
board.
