[Xen-devel] xen/next & xen/stable-2.6.32.x+ depends on CONFIG_ACPI_PROCF
Hello Devs,
I've been making some gentoo ebuilds for the mercurial version of xen because I
just couldn't wait to gentooify Xen 4.0
I came into trouble compiling the kernel and I worked out what was wrong....
Here's the error I got for the sake of completeness:
drivers/acpi/processor_core.c:411: error: static declaration of
‘acpi_processor_add_fs’ follows non-static declaration
include/acpi/processor.h:242: note: previous declaration of
‘acpi_processor_add_fs’ was here
drivers/acpi/processor_core.c:415: error: static declaration of
‘acpi_processor_remove_fs’ follows non-static declaration
include/acpi/processor.h:243: note: previous declaration of
‘acpi_processor_remove_fs’ was here
make[2]: *** [drivers/acpi/processor_core.o] Error 1
make[1]: *** [drivers/acpi] Error 2
make: *** [drivers] Error 2
Here we have a depend on CONFIG_ACPI_PROCFS at build time to include the
structs needed for xen's new ACPI code.

Some people who are just sysadmins not kernel hackers are going to not choose
depreciated options if they are running "Bleeding Edge" as /proc/acpi/* is
"depreciated": http://cateee.net/lkddb/web-lkddb/ACPI_PROCFS.html
I hope I helped someone sharing for a change ;)
