128 * only. Their primary purpose is to access PCI and ISA peripherals.
129 *
130 * Note that for a big endian machine, this implies that the following
131 * big endian mode connectivity is in place.
132 *
133 * The machine specific io.h include defines __io to translate an "IO"
134 * address to a memory address.
135 *
136 * Note that we prevent GCC re-ordering or caching values in expressions
137 * by introducing sequence points into the in*() definitions. Note that
138 * __raw_* do not guarantee this behaviour.
139 *
140 * The {in,out}[bwl] macros are for emulating x86-style PCI/ISA IO space.

19 * Core file format: The core file is written in such a way that gdb
20 * can understand it and provide useful information to the user (under
21 * linux we use the `trad-core' bfd). The file contents are as follows:
22 *
23 * upage: 1 page consisting of a user struct that tells gdb
24 * what is present in the file. Directly after this is a
25 * copy of the task_struct, which is currently not used by gdb,
26 * but it may come in handy at some point. All of the registers
27 * are stored as part of the upage. The upage should always be
28 * only one page long.
29 * data: The data segment follows next. We use current->end_text to
30 * current->brk to pick up all of the user variables, plus any memory
31 * that may have been sbrk'ed. No attempt is made to determine if a
32 * page is demand-zero or if a page is totally unused, we just cover
33 * the entire range. All of the addresses are rounded in such a way
34 * that an integral number of pages is written.
35 * stack: We need the stack information in order to get a meaningful
36 * backtrace. We need to write the data from usp to
37 * current->start_stack, so we round each of these in order to be able
38 * to write an integer number of pages.

4 * Helper macros to generate ELF Note structures, which are put into a
5 * PT_NOTE segment of the final vmlinux image. These are useful for
6 * including name-value pairs of metadata into the kernel binary (or
7 * modules?) for use by external programs.
8 *
9 * Each note has three parts: a name, a type and a desc. The name is
10 * intended to distinguish the note's originator, so it would be a
11 * company, project, subsystem, etc; it must be in a suitable form for
12 * use in a section name. The type is an integer which is used to tag
13 * the data, and is considered to be within the "name" namespace (so
14 * "FooCo"'s type 42 is distinct from "BarProj"'s type 42). The
15 * "desc" field is the actual data. There are no constraints on the
16 * desc field's contents, though typically they're fairly small.
17 *
18 * All notes from a given NAME are put into a section named
19 * .note.NAME. When the kernel image is finally linked, all the notes
20 * are packed into a single .notes section, which is mapped into the
21 * PT_NOTE segment. Because notes for a given name are grouped into
22 * the same section, they'll all be adjacent the output file.
23 *
24 * This file defines macros for both C and assembler use. Their
25 * syntax is slightly different, but they're semantically similar.
26 *
27 * See the ELF specification for more detail about ELF notes.

106 * the gfp_mask should be considered as zone modifiers. Each valid

118 * If the left most zone modifier is a "loner" then the highest valid

120 * Use the first form for GFP_ZONETYPES when the left most bit is not

151 * down.
152 * SUSPEND - like FREEZE, but hardware is doing as much powersaving as
153 * possible. Roughly pci D3.
154 * 151 *
155 * Unfortunately, current drivers only recognize numeric values 0 (ON) and 3 152 * One transition is triggered by resume(), after a suspend() call; the
156 * (SUSPEND). We'll need to fix the drivers. So yes, putting 3 to all different 153 * message is implicit:

158 * previous suspend() which the driver will rely on while
159 * resuming. On most platforms, there are no restrictions on
160 * availability of resources like clocks during resume().
161 *
162 * Other transitions are triggered by messages sent using suspend(). All
163 * these transitions quiesce the driver, so that I/O queues are inactive.
164 * That commonly entails turning off IRQs and DMA; there may be rules
165 * about how to quiesce that are specific to the bus or the device's type.
166 * (For example, network drivers mark the link state.) Other details may
167 * differ according to the message:
168 *
169 * SUSPEND Quiesce, enter a low power device state appropriate for
170 * the upcoming system state (such as PCI_D3hot), and enable
171 * wakeup events as appropriate.
172 *
173 * FREEZE Quiesce operations so that a consistent image can be saved;
174 * but do NOT otherwise enter a low power device state, and do
175 * NOT emit system wakeup events.
176 *
177 * PRETHAW Quiesce as if for FREEZE; additionally, prepare for restoring
178 * the system from a snapshot taken after an earlier FREEZE.
179 * Some drivers will need to reset their hardware state instead
180 * of preserving it, to ensure that it's never mistaken for the
181 * state which that earlier snapshot had set up.
182 *
183 * A minimally power-aware driver treats all messages as SUSPEND, fully
184 * reinitializes its device during resume() -- whether or not it was reset
185 * during the suspend/resume cycle -- and can't issue wakeup events.
186 *
187 * More power-aware drivers may also use low power states at runtime as
188 * well as during system sleep states like PM_SUSPEND_STANDBY. They may
189 * be able to use wakeup events to exit from runtime low-power states,
190 * or from system low-power states such as standby or suspend-to-RAM.
