+Description:    Disable L3 cache indices
+
+                These files exist in every CPU's cache/index3 directory. Each
+                cache_disable_{0,1} file corresponds to one disable slot which
+                can be used to disable a cache index. Reading from these files
+                on a processor with this functionality will return the currently
+                disabled index for that node. There is one L3 structure per
+                node, or per internal node on MCM machines. Writing a valid
+                index to one of these files will cause the specificed cache
+                index to be disabled.
+
+                All AMD processors with L3 caches provide this functionality.
+                For details, see BKDGs at

+Description:
+                Some servers used internally at Google have firmware
+                that provides callback functionality via explicit SMI
+                triggers.  Some of the callbacks are similar to those
+                provided by the EFI runtime services page, but due to
+                historical reasons this different entry-point has been
+                used.
+
+                The gsmi driver implements the kernel's abstraction for
+                these firmware callbacks.  Currently, this functionality
+                is limited to handling the system event log and getting
+                access to EFI-style variables stored in nvram.

-Fields 
-~~~~~~
-g_list: Node in the global device list.
-
-node:   Node in device's parent's children list.
-
-bus_list: Node in device's bus's devices list.
-
-driver_list:   Node in device's driver's devices list.
-
-intf_list:     List of intf_data. There is one structure allocated for
-               each interface that the device supports.
-
-children:      List of child devices.
-
-parent:        *** FIXME ***
-
-name:          ASCII description of device. 
-               Example: " 3Com Corporation 3c905 100BaseTX [Boomerang]"
-
-bus_id:        ASCII representation of device's bus position. This 
-               field should be a name unique across all devices on the
-               bus type the device belongs to. 
-
-               Example: PCI bus_ids are in the form of
-               <bus number>:<slot number>.<function number> 
-               This name is unique across all PCI devices in the system.
-
-lock:          Spinlock for the device. 
-
-refcount:      Reference count on the device.
-
-bus:           Pointer to struct bus_type that device belongs to.
-
-dir:           Device's sysfs directory.
-
-class_num:     Class-enumerated value of the device.
-
-driver:        Pointer to struct device_driver that controls the device.
-
-driver_data:   Driver-specific data.
-
-platform_data: Platform data specific to the device.
-
-               Example:  for devices on custom boards, as typical of embedded
-               and SOC based hardware, Linux often uses platform_data to point
-               to board-specific structures describing devices and how they
-               are wired.  That can include what ports are available, chip
-               variants, which GPIO pins act in what additional roles, and so
-               on.  This shrinks the "Board Support Packages" (BSPs) and
-               minimizes board-specific #ifdefs in drivers.
-
-current_state: Current power state of the device.
-
-saved_state:   Pointer to saved state of the device. This is usable by
-               the device driver controlling the device.
-
-release:       Callback to free the device after all references have 
-               gone away. This should be set by the allocator of the 
-               device (i.e. the bus driver that discovered the device).

 Suspend notifiers

-There are some operations that device drivers may want to carry out in their
-.suspend() routines, but shouldn't, because they can cause the hibernation or
-suspend to fail. For example, a driver may want to allocate a substantial amount
-of memory (like 50 MB) in .suspend(), but that shouldn't be done after the
-swsusp's memory shrinker has run.

-Also, there may be some operations, that subsystems want to carry out before a
-hibernation/suspend or after a restore/resume, requiring the system to be fully
-functional, so the drivers' .suspend() and .resume() routines are not suitable
-for this purpose.  For example, device drivers may want to upload firmware to
-their devices after a restore from a hibernation image, but they cannot do it by
-calling request_firmware() from their .resume() routines (user land processes
-are frozen at this point).  The solution may be to load the firmware into
-memory before processes are frozen and upload it from there in the .resume()
-routine.  Of course, a hibernation notifier may be used for this purpose.
