+What:           security/evm
+Date:           March 2011
+Contact:        Mimi Zohar <zohar@us.ibm.com>
+Description:
+                EVM protects a file's security extended attributes(xattrs)
+                against integrity attacks. The initial method maintains an
+                HMAC-sha1 value across the extended attributes, storing the
+                value as the extended attribute 'security.evm'.
+
+                EVM depends on the Kernel Key Retention System to provide it
+                with a trusted/encrypted key for the HMAC-sha1 operation.
+                The key is loaded onto the root's keyring using keyctl.  Until
+                EVM receives notification that the key has been successfully
+                loaded onto the keyring (echo 1 > <securityfs>/evm), EVM
+                can not create or validate the 'security.evm' xattr, but
+                returns INTEGRITY_UNKNOWN.  Loading the key and signaling EVM
+                should be done as early as possible.  Normally this is done
+                in the initramfs, which has already been measured as part
+                of the trusted boot.  For more information on creating and
+                loading existing trusted/encrypted keys, refer to:
+                Documentation/keys-trusted-encrypted.txt.  (A sample dracut
+                patch, which loads the trusted/encrypted key and enables
+                EVM, is available from http://linux-ima.sourceforge.net/#EVM.)

+                /sys/bus/usb/devices/usbN/../companion
+Date:           January 2007
+KernelVersion:  2.6.21
+Contact:        Alan Stern <stern@rowland.harvard.edu>
+Description:
+                PCI-based EHCI USB controllers (i.e., high-speed USB-2.0
+                controllers) are often implemented along with a set of
+                "companion" full/low-speed USB-1.1 controllers.  When a
+                high-speed device is plugged in, the connection is routed
+                to the EHCI controller; when a full- or low-speed device
+                is plugged in, the connection is routed to the companion
+                controller.
+
+                Sometimes you want to force a high-speed device to connect
+                at full speed, which can be accomplished by forcing the
+                connection to be routed to the companion controller.
+                That's what this file does.  Writing a port number to the
+                file causes connections on that port to be routed to the
+                companion controller, and writing the negative of a port
+                number returns the port to normal operation.
+
+                For example: To force the high-speed device attached to
+                port 4 on bus 2 to run at full speed:
+
+                        echo 4 >/sys/bus/usb/devices/usb2/../companion
+
+                To return the port to high-speed operation:
+
+                        echo -4 >/sys/bus/usb/devices/usb2/../companion
+
+                Reading the file gives the list of ports currently forced
+                to the companion controller.
+
+                Note: Some EHCI controllers do not have companions; they
+                may contain an internal "transaction translator" or they
+                may be attached directly to a "rate-matching hub".  This
+                mechanism will not work with such controllers.  Also, it
+                cannot be used to force a port on a high-speed hub to
+                connect at full speed.
+
+                Note: When this file was first added, it appeared in a
+                different sysfs directory.  The location given above is
+                correct for 2.6.35 (and probably several earlier kernel
+                versions as well).

+                be enabled for the device and the USB device directory will
+                contain a file named power/usb2_hardware_lpm.  The file holds
