linux-2.6.34: add unwinding to om-gta02's defconfig
Adding unwinding remove CONFIG_FRAME_POINTER while preserving its
debug functionalities at the cost of a bigger image
(that we mitigate by using LZMA compression instead of gzip)
Pratically speaking that should result in speed improvements:
Speed seem to be faster but was not tested scientifically.
Here's the unwinding help:
This option enables stack unwinding support in the kernel
using the information automatically generated by the
compiler. The resulting kernel image is slightly bigger but
the performance is not affected. Currently, this feature
only works with EABI compilers. If unsure say Y.
And the frame pointer help:
If you say N here, the resulting kernel will be slightly smaller and
faster. However, if neither FRAME_POINTER nor ARM_UNWIND are enabled,
when a problem occurs with the kernel, the information that is
reported is severely limited.
