That's why I thought you asked... :-)
I thought that some of my problems stemmed from the cross-compiler and
native compiler doing things differently. However, I'm now running a
natively compiled kernel (yep, it took a while to build, but it
boots... so no screwdriver ;-) and am still seeing the same ABI
problems, with the same debug message:
get_entries: 668 != 672
The ARM CPU looks to be 32-bit (Wikipedia suggests that all ARM CPUs
32-bit). The vmlinux that gets generated by both the cross-compiler
and the native compiler is 32-bit. So, I guess this has nothing to do
with 64-bit-ness?
So, if its possible, I'm more confused than I was before! :-)
This has obviously got something to do with alignment. However, I'm a
bit too naive to understand how the alignment is getting messed up
when the kernel and userspace are built with the same compiler. That
said, I don't know what compiler libc was built with... but I assume
the Debian guys built it with the stock compiler for the distro...
Any other ideas? :-)
peace & happiness,
martin
