+     <para>
+	The clock framework defines programming interfaces to support
+	software management of the system clock tree.
+	This framework is widely used with System-On-Chip (SOC) platforms
+	to support power management and various devices which may need
+	custom clock rates.
+	Note that these "clocks" don't relate to timekeeping or real
+	time clocks (RTCs), each of which have separate frameworks.
+	These <structname>struct clk</structname> instances may be used
+	to manage for example a 96 MHz signal that is used to shift bits
+	into and out of peripherals or busses, or otherwise trigger
+	synchronous state machine transitions in system hardware.
+     </para>
+
+     <para>
+	Power management is supported by explicit software clock gating:
+	unused clocks are disabled, so the system doesn't waste power
+	changing the state of transistors that aren't in active use.
+	On some systems this may be backed by hardware clock gating,
+	where clocks are gated without being disabled in software.
+	Sections of chips that are powered but not clocked may be able
+	to retain their last state.
+	This low power state is often called a <emphasis>retention
+	mode</emphasis>.
+	This mode still incurs leakage currents, especially with finer
+	circuit geometries, but for CMOS circuits power is mostly used
+	by clocked state changes.
+     </para>
+
+     <para>
+	Power-aware drivers only enable their clocks when the device
+	they manage is in active use.  Also, system sleep states often
+	differ according to which clock domains are active:  while a
+	"standby" state may allow wakeup from several active domains, a
+	"mem" (suspend-to-RAM) state may require a more wholesale shutdown
+	of clocks derived from higher speed PLLs and oscillators, limiting
+	the number of possible wakeup event sources.  A driver's suspend
+	method may need to be aware of system-specific clock constraints
+	on the target sleep state.
+     </para>
+
+     <para>
+        Some platforms support programmable clock generators.  These
+	can be used by external chips of various kinds, such as other

+=================
+
+This is a graphics framebuffer driver for AMD Geode GX2 based processors.
+
+Advantages:
+
+ * No need to use AMD's VSA code (or other VESA emulation layer) in the
+   BIOS.
+ * It provides a nice large console (128 cols + 48 lines with 1024x768)

+ * You can run XF68_FBDev on top of /dev/fb0
+ * Most important: boot logo :-)
+
+Disadvantages:
+
+ * graphic mode is slower than text mode...
+
+
+How to use it?
+==============
+
+Switching modes is done using  gxfb.mode_option=<resolution>... boot
+parameter or using `fbset' program.
+
+See Documentation/fb/modedb.txt for more information on modedb

+
+

+===
+
+XF68_FBDev should generally work fine, but it is non-accelerated.
+
+
+Configuration
+=============
+
+You can pass kernel command line options to gxfb with gxfb.<option>.
+For example, gxfb.mode_option=800x600@75.
+Accepted options:

 Components of Memory Policies

+    A Linux memory policy consists of a "mode", optional mode flags, and an
+    optional set of nodes.  The mode determines the behavior of the policy,
+    the optional mode flags determine the behavior of the mode, and the
+    optional set of nodes can be viewed as the arguments to the policy
+    behavior.
 
    Internally, memory policies are implemented by a reference counted
    structure, struct mempolicy.  Details of this structure will be discussed
    in context, below, as required to explain the behavior.
 
-	Note:  in some functions AND in the struct mempolicy itself, the mode
-	is called "policy".  However, to avoid confusion with the policy tuple,
-	this document will continue to use the term "mode".
-
    Linux memory policy supports the following 4 behavioral modes:
 
-	Default Mode--MPOL_DEFAULT:  The behavior specified by this mode is
-	context or scope dependent.
-
-	    As mentioned in the Policy Scope section above, during normal
-	    system operation, the System Default Policy is hard coded to
-	    contain the Default mode.
-
-	    In this context, default mode means "local" allocation--that is
-	    attempt to allocate the page from the node associated with the cpu
-	    where the fault occurs.  If the "local" node has no memory, or the
-	    node's memory can be exhausted [no free pages available], local
-	    allocation will "fallback to"--attempt to allocate pages from--
-	    "nearby" nodes, in order of increasing "distance".
+	Default Mode--MPOL_DEFAULT:  This mode is only used in the memory
+	policy APIs.  Internally, MPOL_DEFAULT is converted to the NULL
+	memory policy in all policy scopes.  Any existing non-default policy
+	will simply be removed when MPOL_DEFAULT is specified.  As a result,
+	MPOL_DEFAULT means "fall back to the next most specific policy scope."
 
-		Implementation detail -- subject to change:  "Fallback" uses
-		a per node list of sibling nodes--called zonelists--built at
-		boot time, or when nodes or memory are added or removed from
-		the system [memory hotplug].  These per node zonelist are
-		constructed with nodes in order of increasing distance based
-		on information provided by the platform firmware.
+	    For example, a NULL or default task policy will fall back to the
+	    system default policy.  A NULL or default vma policy will fall
+	    back to the task policy.
 
-	    When a task/process policy or a shared policy contains the Default
-	    mode, this also means "local allocation", as described above.
+	    When specified in one of the memory policy APIs, the Default mode
+	    does not use the optional set of nodes.
 
-	    In the context of a VMA, Default mode means "fall back to task
-	    policy"--which may or may not specify Default mode.  Thus, Default
-	    mode can not be counted on to mean local allocation when used
-	    on a non-shared region of the address space.  However, see
-	    MPOL_PREFERRED below.
-
-	    The Default mode does not use the optional set of nodes.
+	    It is an error for the set of nodes specified for this policy to
+	    be non-empty.
 
 	MPOL_BIND:  This mode specifies that memory must come from the
-	set of nodes specified by the policy.
-
-	    The memory policy APIs do not specify an order in which the nodes
-	    will be searched.  However, unlike "local allocation", the Bind
-	    policy does not consider the distance between the nodes.  Rather,
-	    allocations will fallback to the nodes specified by the policy in
-	    order of numeric node id.  Like everything in Linux, this is subject
-	    to change.
+	set of nodes specified by the policy.  Memory will be allocated from
+	the node in the set with sufficient free memory that is closest to
+	the node where the allocation takes place.
 
 	MPOL_PREFERRED:  This mode specifies that the allocation should be
 	attempted from the single node specified in the policy.  If that
-	allocation fails, the kernel will search other nodes, exactly as
-	it would for a local allocation that started at the preferred node
-	in increasing distance from the preferred node.  "Local" allocation

 	    Internally, the Preferred policy uses a single node--the
-	    preferred_node member of struct mempolicy.  A "distinguished
-	    value of this preferred_node, currently '-1', is interpreted
-	    as "the node containing the cpu where the allocation takes

 	    the temporary interleaved system default policy works in this
 	    mode.
 
+   Linux memory policy supports the following optional mode flags:
+
+	MPOL_F_STATIC_NODES:  This flag specifies that the nodemask passed by
+	the user should not be remapped if the task or VMA's set of allowed
+	nodes changes after the memory policy has been defined.
+
+	    Without this flag, anytime a mempolicy is rebound because of a
+	    change in the set of allowed nodes, the node (Preferred) or
+	    nodemask (Bind, Interleave) is remapped to the new set of
+	    allowed nodes.  This may result in nodes being used that were
+	    previously undesired.
+
+	    With this flag, if the user-specified nodes overlap with the
+	    nodes allowed by the task's cpuset, then the memory policy is
+	    applied to their intersection.  If the two sets of nodes do not
+	    overlap, the Default policy is used.
+
+	    For example, consider a task that is attached to a cpuset with
+	    mems 1-3 that sets an Interleave policy over the same set.  If
+	    the cpuset's mems change to 3-5, the Interleave will now occur
+	    over nodes 3, 4, and 5.  With this flag, however, since only node
+	    3 is allowed from the user's nodemask, the "interleave" only
+	    occurs over that node.  If no nodes from the user's nodemask are
+	    now allowed, the Default behavior is used.
+
+	    MPOL_F_STATIC_NODES cannot be combined with the
+	    MPOL_F_RELATIVE_NODES flag.  It also cannot be used for
+	    MPOL_PREFERRED policies that were created with an empty nodemask
+	    (local allocation).
+
+	MPOL_F_RELATIVE_NODES:  This flag specifies that the nodemask passed
+	by the user will be mapped relative to the set of the task or VMA's
+	set of allowed nodes.  The kernel stores the user-passed nodemask,
+	and if the allowed nodes changes, then that original nodemask will
+	be remapped relative to the new set of allowed nodes.
+
+	    Without this flag (and without MPOL_F_STATIC_NODES), anytime a
+	    mempolicy is rebound because of a change in the set of allowed
+	    nodes, the node (Preferred) or nodemask (Bind, Interleave) is
+	    remapped to the new set of allowed nodes.  That remap may not
+	    preserve the relative nature of the user's passed nodemask to its
+	    set of allowed nodes upon successive rebinds: a nodemask of
+	    1,3,5 may be remapped to 7-9 and then to 1-3 if the set of
+	    allowed nodes is restored to its original state.
+
+	    With this flag, the remap is done so that the node numbers from
+	    the user's passed nodemask are relative to the set of allowed
+	    nodes.  In other words, if nodes 0, 2, and 4 are set in the user's
+	    nodemask, the policy will be effected over the first (and in the
+	    Bind or Interleave case, the third and fifth) nodes in the set of
+	    allowed nodes.  The nodemask passed by the user represents nodes
+	    relative to task or VMA's set of allowed nodes.
+
+	    If the user's nodemask includes nodes that are outside the range
+	    of the new set of allowed nodes (for example, node 5 is set in
+	    the user's nodemask when the set of allowed nodes is only 0-3),
+	    then the remap wraps around to the beginning of the nodemask and,
+	    if not already set, sets the node in the mempolicy nodemask.
+
+	    For example, consider a task that is attached to a cpuset with
+	    mems 2-5 that sets an Interleave policy over the same set with
+	    MPOL_F_RELATIVE_NODES.  If the cpuset's mems change to 3-7, the
+	    interleave now occurs over nodes 3,5-6.  If the cpuset's mems
+	    then change to 0,2-3,5, then the interleave occurs over nodes
+	    0,3,5.
+
+	    Thanks to the consistent remapping, applications preparing
+	    nodemasks to specify memory policies using this flag should
+	    disregard their current, actual cpuset imposed memory placement
+	    and prepare the nodemask as if they were always located on
+	    memory nodes 0 to N-1, where N is the number of memory nodes the
+	    policy is intended to manage.  Let the kernel then remap to the
+	    set of memory nodes allowed by the task's cpuset, as that may
+	    change over time.
+
+	    MPOL_F_RELATIVE_NODES cannot be combined with the
+	    MPOL_F_STATIC_NODES flag.  It also cannot be used for
+	    MPOL_PREFERRED policies that were created with an empty nodemask
+	    (local allocation).
+
+MEMORY POLICY REFERENCE COUNTING
+
+To resolve use/free races, struct mempolicy contains an atomic reference
+count field.  Internal interfaces, mpol_get()/mpol_put() increment and
+decrement this reference count, respectively.  mpol_put() will only free
+the structure back to the mempolicy kmem cache when the reference count
+goes to zero.
+
+When a new memory policy is allocated, it's reference count is initialized
+to '1', representing the reference held by the task that is installing the
+new policy.  When a pointer to a memory policy structure is stored in another
+structure, another reference is added, as the task's reference will be dropped
+on completion of the policy installation.
+
+During run-time "usage" of the policy, we attempt to minimize atomic operations
+on the reference count, as this can lead to cache lines bouncing between cpus
+and NUMA nodes.  "Usage" here means one of the following:
+
+1) querying of the policy, either by the task itself [using the get_mempolicy()
+   API discussed below] or by another task using the /proc/<pid>/numa_maps
+   interface.
+
+2) examination of the policy to determine the policy mode and associated node
+   or node lists, if any, for page allocation.  This is considered a "hot
+   path".  Note that for MPOL_BIND, the "usage" extends across the entire
+   allocation process, which may sleep during page reclaimation, because the
+   BIND policy nodemask is used, by reference, to filter ineligible nodes.
+
+We can avoid taking an extra reference during the usages listed above as
+follows:
+
+1) we never need to get/free the system default policy as this is never
+   changed nor freed, once the system is up and running.
+
+2) for querying the policy, we do not need to take an extra reference on the
+   target task's task policy nor vma policies because we always acquire the
+   task's mm's mmap_sem for read during the query.  The set_mempolicy() and
+   mbind() APIs [see below] always acquire the mmap_sem for write when
+   installing or replacing task or vma policies.  Thus, there is no possibility
+   of a task or thread freeing a policy while another task or thread is
+   querying it.
+
+3) Page allocation usage of task or vma policy occurs in the fault path where
+   we hold them mmap_sem for read.  Again, because replacing the task or vma
+   policy requires that the mmap_sem be held for write, the policy can't be
+   freed out from under us while we're using it for page allocation.
+
+4) Shared policies require special consideration.  One task can replace a
+   shared memory policy while another task, with a distinct mmap_sem, is
+   querying or allocating a page based on the policy.  To resolve this
+   potential race, the shared policy infrastructure adds an extra reference
+   to the shared policy during lookup while holding a spin lock on the shared
+   policy management structure.  This requires that we drop this extra
+   reference when we're finished "using" the policy.  We must drop the
+   extra reference on shared policies in the same query/allocation paths
+   used for non-shared policies.  For this reason, shared policies are marked
+   as such, and the extra reference is dropped "conditionally"--i.e., only
+   for shared policies.
+
+   Because of this extra reference counting, and because we must lookup
+   shared policies in a tree structure under spinlock, shared policies are
+   more expensive to use in the page allocation path.  This is expecially
+   true for shared policies on shared memory regions shared by tasks running
+   on different NUMA nodes.  This extra overhead can be avoided by always
+   falling back to task or system default policy for shared memory regions,
+   or by prefaulting the entire shared memory region into memory and locking
+   it down.  However, this might not be appropriate for all applications.
