e3bbff9f3c [SCSI] megaraid_sas: FW transition and q size changes
This patch has the following enhancements :
        a. handles new transition states of FW to support controller hotplug.
        b. It reduces by 1 the maximum cmds that the driver may send to FW.
        c. Sends "Stop Processing" cmd to FW before returning failure from reset routine
        d. Adds print in megasas_transition routine
        e. Sends "RESET" flag to FW to do a soft reset of controller
to move from Operational to Ready state.
	f. Sending correct pointer (cmd->sense) to pci_pool_free

0e98936c92 [SCSI] megaraid_sas: zcr with fix
The patch adds support for a ZCR controller (Device ID : 0x413).

It also has a critical bug fix :

Disable controller interrupt before firing INIT cmd to FW.  Interrupt
is enabled after required initialization is over. This is done to
ensure that driver is ready to handle interrupts when it is generated
by the controller.

1341c93922 [SCSI] megaraid_sas: new template defined to represent each type of controllers
This patch defines a new template to represent each type of
controllers (identified by the processor used). The template has
members that is set with appropriate values during driver
initialisation. This change is done to support new controllers with
minimal change to existing code. In future, for a new controller
support, a template will be declared and its members initialised
appropriately.
