Precise update to 3.2.38 stable release

SRU Justification

    Impact:
       The upstream process for stable tree updates is quite similar
       in scope to the Ubuntu SRU process, e.g., each patch has to
       demonstrably fix a bug, and each patch is vetted by upstream
       by originating either directly from Linus' tree or in a minimally
       backported form of that patch. The 3.2.38 upstream stable
       patch set is now available. It should be included in the Ubuntu
       kernel as well.

       git://git.kernel.org/

Linux 3.2.38

These patches were not applied as they were already in Precise:
PCI: Allow pcie_aspm=force even when FADT indicates it is unsupported
ALSA: usb-audio: Fix regression by disconnection-race-fix patch

The patch "x86: Use enum instead of literals for trap values" needed a small modification due to differences in do_iret_error, because of the nx emulation patch present in Precise.

The patch "UBUNTU: SAUCE: samsung-laptop: disable in UEFI mode" was reverted, as it's superseded by these two patches in 3.2.38:
efi: Make 'efi_enabled' a function to query EFI facilities
samsung-laptop: Disable on EFI hardware
