* 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.
*

*
* Instead of keeping dirty/clean pages in per address-space lists, we instead

* In either case (swapcache or inode backed), the pagecache itself holds one
* reference to the page. Setting PG_private should also increment the
* refcount. The each user mapping also has a reference to the page.
*
* There is also a per-mapping radix tree mapping index to the page
* in memory if present. The tree is rooted at mapping->root.
* The pagecache pages are stored in a per-mapping radix tree, which is

* - private pages which have been modified may need to be swapped out
* to swap space and (later) to be read back into memory.

* There are 4 important states driver can be in:
* ON -- driver is working
* FREEZE -- stop operations and apply whatever policy is applicable to a
* suspended driver of that class, freeze queues for block like IDE
* 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.
