    >ACPI: Add "acpi.power_nocheck=1" to disable power state check in
power transition:

   >WARNING: at linux-2.6/fs/sysfs/dir.c:463  sysfs_add_one+0x33/0x39()
   >sysfs: duplicate filename 'acpi' can not be created
   >kobject_add_internal failed for acpi with -EEXIST, don't try to register
            things with the same name in the same directory

   In the above commit the "acpi.power_nocheck" module parameter is defined
in drivers/acpi/power.c file. As several module parameters using the same ACPI
prefix are defined in the different files(for example: power_nocheck is
defined in drivers/acpi/power.c,debug_layer/debug_level are defined in
drivers/acpi/debug.c) and there exists another module between them, the
warning message will be printed when using the current generic param code.
(In the function of param_sysfs_init).

   In fact when ACPI is selected, the drivers/acpi/power will also be compiled
as built-in kernel.So this issue can be fixed by the following approach.
   workaround it by adjusting the module link order in drivers/acpi/Makefile.
In such case the module parameter using the same prefix(ACPI) are put together
in the param data section.

   Of course the better solution is to fix it in generic param code related
with sysfs.
