Description of problem:
memcpy_fromio and memcpy_toio are missing from kernel. Many modules,
including sound drivers refuse to load because of that. Seems that
nobody in the vmlinux uses them so linker leaves them out.
Current kernel: 2.6.3-2.1.253. Happened with .246 kernel too.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Compile kernel with stock x86_64 options
Actual Results: memcpy_fromio and memcpy_toio are not in vmlinux
Expected Results: Well, they should be in vmlinux as drivers need it.
The precompiled kernel rpm suffers from this same problem.
Andi Kleen just sent a fix to this to Linus; we'll pick that up in a
day or two.
