SubjectFix for __you_cannot_kmalloc_that_much failure with gcc 3.2

And here you go, this is a unified patch fixing both bugs. The dmi-id
part is unchanged. Testers and reviewers are welcome.

* * * * *

gcc 3.2 has a hard time coping with the code in dmi_id_init():

drivers/built-in.o(.init.text+0x789e): In function `dmi_id_init':
: undefined reference to `__you_cannot_kmalloc_that_much'
make: *** [.tmp_vmlinux1] Error 1

Moving half of the code to a separate function seems to help. This is
a no-op for gcc 4.1 which will successfully inline the code anyway.

Tested-by: Kamalesh Babulal <kamalesh@linux.vnet.ibm.com>

A similar problem has been reported in snd_mixer_oss_build_input(),
fix it as well.
