I actually don't have anything remotely like ES7000 iether. I just
found the problem while tracking down another randconfig failure.

Seems it would be cleaner to figure out some way to build es7000.c for
if CONFIG_X86_ES7000 is set? Or just move them here all the time?

It seems that this #ifndef is not needed -- even if there is another
declaration of these functions that is visible, the signatures should
match so it should be OK.
I just finished my test builds with and without GENERIC, so I can
suggest just move all functions to arch/i386/mach-es7000/es7000plat.c
- es7000_sw_apic() ,es7000_enable_apic_mode(),acpi_madt_oem_check(),
mps_oem_check() and make them non-static - from
arch/i386/mach-generic/es7000.c and I think I externed couple things
in asm/mach-es7000/mach_apic.h. So the file
arch/i386/mach-generic/es7000.c looks very simple:
/* * APIC driver for the Unisys ES7000 chipset.
*/
#define APIC_DEFINITION 1
#include <linux/threads.h>
#include <linux/cpumask.h>
#include <asm/smp.h>
#include <asm/mpspec.h>
#include <asm/genapic.h>
#include <asm/fixmap.h>
#include <asm/apicdef.h>
#include <linux/kernel.h>
#include <linux/string.h>
#include <linux/smp.h>
#include <linux/init.h>
#include <asm/mach-es7000/mach_apicdef.h>
#include <asm/mach-es7000/mach_apic.h>
#include <asm/mach-es7000/mach_ipi.h>
#include <asm/mach-es7000/mach_mpparse.h>
#include <asm/mach-es7000/mach_wakecpu.h>
static int probe_es7000(void)
{
/* probed later in mptable/ACPI hooks */
return 0;
}
struct genapic apic_es7000 = APIC_INIT("es7000", probe_es7000);
and no ifdefs. Sorry for this skimpy description without actual patch...
I can send a patch later on, or you guys can try it yourselves :)
sorry have such a tight time this afternoon, only can back to my
computer after 7-8 pm...
