-  The monolithic patch was broken into four patches that represent discrete functionality (boot and build, reboot/halt shutdown, Sx shutdown, forcing DMAR on).  An appropriate (and more descriptive) patch description was added to each patch.

-  Small stylistic cleanups (capitalization, comment wording, whitespace, etc.).

-  The code in hwsleep.c that populated the tboot ACPI structures was moved into its own function in tboot.c.

-  Use pr_warning(), pr_info(), pr_debug().

-  Moved some #include's from the middle of tboot.c to the top.

-  Changed the memory type of the tboot shared page from E820_UNUSABLE to E820_RESERVED (really a change to tboot, but requires a change here in the checking code).

And the new patches that I'm about to send have notes in the top indicating their changes from the previous versions.
