Implementation of the new functions for SE AP support: bind, unbind and associate. There are two new sysfs attributes for this: /sys/devices/ap/cardxx/xx.yyyy/se_bind /sys/devices/ap/cardxx/xx.yyyy/se_associate Writing a 1 into the se_bind attribute triggers the SE AP bind for this AP queue, writing a 0 into does an unbind - that's a reset (RAPQ) with the F bit enabled. The se_associate attribute needs an integer value in range 0...2^16-1 written in. This is the index into a secrets table feed into the ultravisor. For more details please see the Architecture documents. These both new ap queue attributes are only visible inside a SE guest with SB (Secure Binding) available.
