+ *
+ *  upage: 1 page consisting of a user struct that tells gdb

+ *      copy of the task_struct, which is currently not used by gdb,

+ *      are stored as part of the upage.  The upage should always be
+ *      only one page long.
+ *  data: The data segment follows next.  We use current->end_text to
+ *      current->brk to pick up all of the user variables, plus any memory
+ *      that may have been sbrk'ed.  No attempt is made to determine if a
+ *      page is demand-zero or if a page is totally unused, we just cover
+ *      the entire range.  All of the addresses are rounded in such a way
+ *      that an integral number of pages is written.
+ *  stack: We need the stack information in order to get a meaningful
+ *      backtrace.  We need to write the data from usp to
+ *      current->start_stack, so we round each of these in order to be able
+ *      to write an integer number of pages.

+ * Helper macros to generate ELF Note structures, which are put into a
+ * PT_NOTE segment of the final vmlinux image.  These are useful for
+ * including name-value pairs of metadata into the kernel binary (or
+ * modules?) for use by external programs.
+ *
+ * Each note has three parts: a name, a type and a desc.  The name is
+ * intended to distinguish the note's originator, so it would be a
+ * company, project, subsystem, etc; it must be in a suitable form for
+ * use in a section name.  The type is an integer which is used to tag
+ * the data, and is considered to be within the "name" namespace (so
+ * "FooCo"'s type 42 is distinct from "BarProj"'s type 42).  The
+ * "desc" field is the actual data.  There are no constraints on the
+ * desc field's contents, though typically they're fairly small.
+ *
+ * All notes from a given NAME are put into a section named
+ * .note.NAME.  When the kernel image is finally linked, all the notes
+ * are packed into a single .notes section, which is mapped into the
+ * PT_NOTE segment.  Because notes for a given name are grouped into
+ * the same section, they'll all be adjacent the output file.
+ *
+ * This file defines macros for both C and assembler use.  Their
+ * syntax is slightly different, but they're semantically similar.

- * There are 4 important states driver can be in:

- *           does, drop packets for ethernet, etc... stop DMA engine too etc...
- *           so a consistent image can be saved; but do not power any hardware
- *           down.
- * SUSPEND - like FREEZE, but hardware is doing as much powersaving as
- *           possible. Roughly pci D3.
+ * Several driver power state transitions are externally visible, affecting
+ * the state of pending I/O queues and (for drivers that touch hardware)
+ * interrupts, wakeups, DMA, and other hardware state.  There may also be
+ * internal transitions to various low power modes, which are transparent
+ * to the rest of the driver stack (such as a driver that's ON gating off
+ * clocks which are not in active use).
  *
- * Unfortunately, current drivers only recognize numeric values 0 (ON) and 3
- * (SUSPEND).  We'll need to fix the drivers. So yes, putting 3 to all different
- * defines is intentional, and will go away as soon as drivers are fixed.  Also
- * note that typedef is neccessary, we'll probably want to switch to
- *   typedef struct pm_message_t { int event; int flags; } pm_message_t
- * or something similar soon.
+ * One transition is triggered by resume(), after a suspend() call; the
+ * message is implicit:
+ *
+ * ON           Driver starts working again, responding to hardware events
+ *              and software requests.  The hardware may have gone through
+ *              a power-off reset, or it may have maintained state from the
+ *              previous suspend() which the driver will rely on while
+ *              resuming.  On most platforms, there are no restrictions on
+ *              availability of resources like clocks during resume().
+ *
+ * Other transitions are triggered by messages sent using suspend().  All
+ * these transitions quiesce the driver, so that I/O queues are inactive.
+ * That commonly entails turning off IRQs and DMA; there may be rules
+ * about how to quiesce that are specific to the bus or the device's type.
+ * (For example, network drivers mark the link state.)  Other details may
+ * differ according to the message:
+ *
+ * SUSPEND      Quiesce, enter a low power device state appropriate for
+ *              the upcoming system state (such as PCI_D3hot), and enable
+ *              wakeup events as appropriate.
+ *
+ * FREEZE       Quiesce operations so that a consistent image can be saved;
+ *              but do NOT otherwise enter a low power device state, and do
+ *              NOT emit system wakeup events.
+ *
+ * PRETHAW      Quiesce as if for FREEZE; additionally, prepare for restoring
+ *              the system from a snapshot taken after an earlier FREEZE.
+ *              Some drivers will need to reset their hardware state instead
+ *              of preserving it, to ensure that it's never mistaken for the
+ *              state which that earlier snapshot had set up.
+ *
+ * A minimally power-aware driver treats all messages as SUSPEND, fully
+ * reinitializes its device during resume() -- whether or not it was reset
+ * during the suspend/resume cycle -- and can't issue wakeup events.
+ *
+ * More power-aware drivers may also use low power states at runtime as
+ * well as during system sleep states like PM_SUSPEND_STANDBY.  They may
+ * be able to use wakeup events to exit from runtime low-power states,
+ * or from system low-power states such as standby or suspend-to-RAM.
