    ACPI processor: remove spurious newline from warning message
    
    Commit 4973b22a ("ACPI processor: reset the throttling state once it's
    invalid") introduced a new warning which prints a spurious newline.
    
    The ACPI_WARNING macro that is used already takes care of adding a
    newline, after adding ACPI_CA_VERSION to the message. Remove the newline
    to avoid the message getting split into two lines.

    drm/i915: acpi/video.c fix section mismatch warning
    
    Currently acpi_video_exit() is exported as well as using __exit which causes:
    
      WARNING: drivers/acpi/video.o(__ksymtab+0x0): Section mismatch in reference from the variable __ksymtab_acpi_video_exit to the function .exit.text:acpi_video_exit()
      The symbol acpi_video_exit is exported and annotated __exit
      Fix this by removing the __exit annotation of acpi_video_exit or drop the export.

    ACPI: sanity check _PSS frequency to prevent cpufreq crash
    
    When BIOS SETUP is changed to disable EIST, some BIOS
    hand the OS an un-initialized _PSS:
    
            Name (_PSS, Package (0x06)
            {
                Package (0x06)
                {
                    0x80000000,	// frequency [MHz]
                    0x80000000,	// power [mW]
                    0x80000000,	// latency [us]
                    0x80000000,	// BM latency [us]
                    0x80000000,	// control
                    0x80000000	// status
                },
    	    ...
    
    These are outrageous values for frequency,
    power and latency, raising the question where to draw
    the line between legal and illegal.  We tend to survive
    garbage in the power and latency fields, but we can BUG_ON
    when garbage is in the frequency field.
    
    Cpufreq multiplies the frequency by 1000 and stores it in a u32 KHz.
    So disregard a _PSS with a frequency so large
    that it can't be represented by cpufreq.

    i7300_idle: allow testing on i5000-series hardware w/o re-compile
    
    Testing the i7300_idle driver on i5000-series hardware required
    an edit to i7300_idle.h to "#define SUPPORT_I5000 1" and a re-build
    of both i7300_idle and ioat_dma.
    
    Replace that build-time scheme with a load-time module parameter:
    "7300_idle.forceload=1" to make it easier to test the driver
    on hardware that while not officially validated, works fine
    and is much more commonly available.
    
    By default (no modparam) the driver will continue to load
    only on the i7300.
    
    Note that ioat_dma runs a copy of i7300_idle's probe routine
    to know to reserve an IOAT channel for i7300_idle.
    This change makes ioat_dma do that always on the i5000,
    just like it does on the i7300.

    PCI/ACPI: fix wrong ref count handling in acpi_pci_bind()
    
    The 'dev' field of struct acpi_pci_data is having a pointer to struct
    pci_dev without incrementing the reference counter. Because of this, I
    got the following kernel oops when I was doing some pci hotplug
    operations. This patch fixes this bug by replacing wrong hand-made
    pci_find_slot() with pci_get_slot() in acpi_pci_bind().

    cpuidle: fix AMD C1E suspend hang
    
    When AMD C1E is enabled, local APIC timer will stop even in C1. To avoid
    suspend/resume hang, this patch removes C1 and replace it with a cpu_relax() in
    suspend/resume path. This hasn't any impact in runtime path.
