This export was necessary to compile acpi_memhotplug.c as module.

1. 2.6.17-rc1-mm2

2. 2.6.17-rc1-mm2: badness in 3w_xxxx driver

The following patch: x86-kmap_atomic-debugging.patch exposed a badness
in 3w_xxx driver. I'm getting a lot of:

Apr 9 13:00:04 nickolas kernel: kmap_atomic: local irqs are enabled while using KM_IRQn
Apr 9 13:00:04 nickolas kernel: <c0104103> show_trace+0x13/0x20 <c010412e> dump_stack+0x1e/0x20

Apr 9 13:00:04 nickolas kernel: <c214ffb4> 0xc214ffb4

I'm running 32 bit kernel on AMD64x2 w/ HIGHMEM enabled.
I think this is an old bug since the 3w_xxxx.c has not been changed for
a long time (at least since 2.6.16-rc1-mm4).

Please let me know if you want me to try some patches.
