Hi all,
we had a problem compiling the linux kernel using for an
arm big endian target in the qemu-armeb environment.
The compilation stopped when executing the split-include utility during
the kernel compilation phase: split-include exited with an error of the
stat64 syscall, executed in the environment emulated by qemu.
Qemu seemed to ignore the fact that in big endian systems the fields
st_blocks and its padding are swapped (to allow future expansion of the
field,) so the fix consisted only in swapping the two fields (only in big
endian systems, of course.)
The attached patch should fix the problem.
Regards,
Michael, Fabio and Claudio
