      Introduce CONFIG_SUSPEND for suspend-to-Ram and standby · 296699de
      Rafael J. Wysocki authored 
      
Introduce CONFIG_SUSPEND representing the ability to enter system sleep
states, such as the ACPI S3 state, and allow the user to choose SUSPEND
and HIBERNATION independently of each other.

Make HOTPLUG_CPU be selected automatically if SUSPEND or HIBERNATION has
been chosen and the kernel is intended for SMP systems.

Also, introduce CONFIG_PM_SLEEP which is automatically selected if
CONFIG_SUSPEND or CONFIG_HIBERNATION is set and use it to select the
code needed for both suspend and hibernation.

The top-level power management headers and the ACPI code related to
suspend and hibernation are modified to use the new definitions (the
changes in drivers/acpi/sleep/main.c are, mostly, moving code to reduce
the number of ifdefs).

There are many other files in which CONFIG_PM can be replaced with
CONFIG_PM_SLEEP or even with CONFIG_SUSPEND, but they can be updated in
the future.

Replace CONFIG_SOFTWARE_SUSPEND with CONFIG_HIBERNATION to avoid
confusion (among other things, with CONFIG_SUSPEND introduced in the
next patch).

      [PATCH] encrypt suspend data for easy wiping · c2ff18f4
      Andreas Steinmetz authored 
      
The patch protects from leaking sensitive data after resume from suspend.
During suspend a temporary key is created and this key is used to encrypt the
data written to disk.  When, during resume, the data was read back into memory
the temporary key is destroyed which simply means that all data written to
disk during suspend are then inaccessible so they can't be stolen lateron.

Think of the following: you suspend while an application is running that keeps
sensitive data in memory.  The application itself prevents the data from being
swapped out.  Suspend, however, must write these data to swap to be able to
resume lateron.  Without suspend encryption your sensitive data are then
stored in plaintext on disk.  This means that after resume your sensitive data
are accessible to all applications having direct access to the swap device
which was used for suspend.  If you don't need swap after resume these data
can remain on disk virtually forever.  Thus it can happen that your system
gets broken in weeks later and sensitive data which you thought were encrypted
and protected are retrieved and stolen from the swap device.

      [ACPI] IA64-related ACPI Kconfig fixes · eb7b6b32
      Len Brown authored 
      
Build issues were mostly in the ACPI=n case -- don't do that.
Select ACPI from IA64_GENERIC.
Add some missing dependencies on ACPI.

Mark BLACKLIST_YEAR and some laptop-only ACPI drivers
as X86-only.  Let me know when you get an IA64 Laptop.

      Linux-2.6.12-rc2 · 1da177e4
      Linus Torvalds authored 
      Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
