Subject: ACPI modpost failure in 2.6.23-rc1-git2

Between 2.6.23-rc1-git1 and 2.6.23-rc1-git2 we started getting the
following fatal error during modpost on an x86_64 machine:

FATAL: drivers/acpi/video: sizeof(struct acpi_device_id)=20 is not a
modulo of the size of section __mod_acpi_device_table=48.
Fix definition of struct acpi_device_id in mod_devicetable.h
make[1]: *** [__modpost] Error 1

This check seems to have been added as part of the following commit:

We are compiling a 64bit kernel on a machine with a pretty old
userspace which is 32bit.

Let me know if you need more info.

Will do. That is vile though.

It feels like we should be generating this information in the kernel
build and extracting it from the built kernel.
