Implement SATA AHCI FIS-based switching support. Tested on AMD internal reference board. Signed-off-by: Shane Huang<shane.huang@xxxxxxx> Cc: Tejun Heo<tj@xxxxxxxxxx> --- Changes from the last version(v3): * Rediff for the current upstream kernel as Jeff Garzik asked. Changes from v2: * Move fbs_need_dec from struct ahci_port_priv to ahci_error_intr() as a local variable. * Add BUG_ON(!pp->fbs_enabled) for ahci_fbs_dec_intr(). * Refine the retry loop in ahci_fbs_dec_intr(). * Refine the code to determine failed active link with ap->pmp_link in ahci_error_intr(). * WARN_ON() in ahci_port_intr() can storm the machine with consecutive stack dumps, replace it with WARN_ON_ONCE(). * Refine ahci_enable_fbs()/ahci_disable_fbs(), and discard the message for controllers which do not support FBS. * Add a warning message in ahci_port_start() for those weird controllers which support CAP.FBSS but do not support PxCMD.FBSCP. * Several small corrections for better coding style.
