    ACPI: IA64=y ACPI=n build fix
    
    ia64's sim_defconfig uses CONFIG_ACPI=n
    which now #define's acpi_disabled in <linux/acpi.h>
    
    So we shouldn't re-define it here in <asm/acpi.h>

    ACPI: Kill overly verbose "power state" log messages
    
    I was recently lucky enough to get a 64-CPU system, so my kernel log
    ends up with 64 lines like:
    
        ACPI: CPU0 (power states: C1[C1] C2[C3])
    
    This is pretty useless clutter because this info is already available
    after boot from both /sys/devices/system/cpu/cpu*/cpuidle/state?/ as
    well as /proc/acpi/processor/CPU*/power.
    
    So just delete the code that prints the C-states in processor_idle.c.

    ACPI: fix Compaq Evo N800c (Pentium 4m) boot hang regression
    
    Don't disable ARB_DISABLE when the familary ID is 0x0F.

    This was a 2.6.31 regression, and so this patch
    needs to be applied to 2.6.31.stable

commit 14f03343ad1080c2fea29ab2c13f05b976c4584e

    ACPI: Clarify resource conflict message
    
    The message "ACPI: Device needs an ACPI driver" is misleading. The
    device _may_ need an ACPI driver, if the BIOS implemented a custom
    API for the device in question (which, AFAIK, can't be checked.) If
    not, then either a generic ACPI driver may be used (for example
    "thermal"), or nothing can be done (other than a white list).
    
    I propose to reword the message to:
    
    ACPI: If an ACPI driver is available for this device, you should use
    it instead of the native driver
    
    which I think is more correct. Comments and suggestions welcome.
    
    I also added a message warning about possible problems and system
    instability when users pass acpi_enforce_resources=lax, as suggested
    by Len.
