[PATCH] kill implicit check_acpi_pci() warning

[PATCH] kill implicit check_acpi_pci() warning

[Dave Hansen]

I've been seeing these in recent -mms:

arch/i386/kernel/setup.c: In function `setup_arch':
arch/i386/kernel/setup.c:1523: warning: implicit declaration of function `check_acpi_pci'

The issue is that the stub check_acpi_pci() is inside an
#ifdef ACPI in the header, while the actual use inside the
.c file is not.  I've elected to take both the extern and
the stub in the header, and take them out of the ACPI #ifdef.

The comment next to the call says the following:

	check_acpi_pci();       /* Checks more than just ACPI actually */

Seems weird to have "_acpi_" in it then, but what do I know?

BTW, I'm running a config with ACPI=n and X86_IO_APIC=y.
