Page allocator: clean up pcp draining functions

2008-02-05T17:44:17+00:00

- Add comments explaing how drain_pages() works.

- Eliminate useless functions

- Rename drain_all_local_pages to drain_all_pages(). It does drain
  all pages not only those of the local processor.

- Eliminate useless interrupt off / on sequences. drain_pages()
  disables interrupts on its own. The execution thread is
  pinned to processor by the caller. So there is no need to
  disable interrupts.

- Put drain_all_pages() declaration in gfp.h and remove the
  declarations from suspend.h and from mm/memory_hotplug.c

- Make software suspend call drain_all_pages(). The draining
  of processor local pages is may not the right approach if
  software suspend wants to support SMP. If they call drain_all_pages
  then we can make drain_pages() static.

Hibernation: Invoke suspend notifications after console switch

2008-02-01T23:30:59+00:00

Following the recent change in the suspend code path, switch consoles before
calling PM notifiers during hibernation.

Suspend: Invoke suspend notifications after console switch

2008-02-01T23:30:58+00:00

In order to fix APM emulation it is necessary to enable apm-emulation
notifications for suspends triggered in various ways via the suspend
notifiers.  However, this will cause the systems using APM emulation
to lock up between X being needed to switch away from the VT and X
already waiting for resume in the APM ioctl.

This patch moves the console switch (if enabled) before the suspend
notification (and after the resume notification) to avoid this issue.

Suspend: Add config option to disable the freezer if architecture wants that

2008-02-01T23:30:58+00:00

This patch makes the freezer optional for suspend to allow the
system to work (or not work) like the original PMU suspend.

Hibernation: Introduce begin() and end() callbacks

2008-02-01T23:30:58+00:00

Introduce global hibernation callback .end() and rename global
hibernation callback .start() to .begin(), in analogy with the
recent modifications of the global suspend callbacks.

Suspend: Introduce begin() and end() callbacks

2008-02-01T23:30:56+00:00

On ACPI systems the target state set by acpi_pm_set_target() is
reset by acpi_pm_finish(), but that need not be called if the
suspend fails.  All platforms that use the .set_target() global
suspend callback are affected by analogous issues.

For this reason, we need an additional global suspend callback that
will reset the target state regardless of whether or not the suspend
is successful.  Also, it is reasonable to rename the .set_target()
callback, since it will be used for a different purpose on ACPI
systems (due to ACPI 1.0x code ordering requirements).

Introduce the global suspend callback .end() to be executed at the
end of the suspend sequence and rename the .set_target() global
suspend callback to .begin().

Suspend: Clean up Kconfig (V2)

2008-02-01T23:30:55+00:00

This cleans up the suspend Kconfig and removes the need to
declare centrally which architectures support suspend. All
architectures that currently support suspend are modified
accordingly.
