Description Mike Limansky 2009-05-23 19:40:24 UTC
This tested with gcc-4.4 and gentoo-sources-2.6.29-r4
I have CONFIG_FRAME_WARN=0 in the kernel config and use gcc-4.4. According to the kernel help setting to 0 shall disable the warning.

Reproducible: Always

Steps to Reproduce:
1. Install gcc-4.4
2. Set the CONFIG_FRAME_WARN parameter value to 0.
3. Compile kernel.

Actual Results:  
There are a lot of warnings like: "the frame size of 16 bytes is larger than 0 bytes".

Expected Results:  
There should not be any warning about stack frame size.

Comment 1 SpanKY gentoo-dev 2009-05-23 23:30:21 UTC
has nothing to do with the compiler.  the kernel is wrong.

What's the solution? I have exactly the same problem. I changed nothing except updating gcc.
