Precise update to 3.2.39 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 3.2.39 upstream stable
       patch set is now available. It should be included in the Ubuntu
       kernel as well.

These were dropped from application as they were already applied to Precise:
drm/i915: Fix misplaced intel_mark_page_flip_active()
ptrace: introduce signal_wake_up_state() and ptrace_signal_wake_up()
wake_up_process() should be never used to wakeup a TASK_STOPPED/TRACED task
xen/netback: shutdown the ring if it contains garbage.
xen/netback: don't leak pages on failure in xen_netbk_tx_check_gop.
xen/netback: free already allocated memory on failure in xen_netbk_get_requests
netback: correct netbk_tx_err to handle wrap around.
bridge: Pull ip header into skb->data before looking into ip header.

Also, the patch "ptrace: ensure arch_ptrace/ptrace_request can never race with SIGKILL" was already applied, but reverted and reapplied with the version from 3.2.39, since it is more complete with an additional change to a comment introduced in commit "ptrace/x86: Partly fix set_task_blockstep()->update_debugctlmsr() logic", which also came with 3.2.39.
