Package: linux-2.6
Version: 2.6.18.dfsg.1-24
Severity: critical
Tags: patch
Justification: breaks unrelated software

Uninexistant syscalls on mips/mipsel return -ENOSYS errno instead of 
ENOSYS. Moreover in some cases it even returns EINVAL instead of ENOSYS.
This make userland software like glibc or coreutils unable to detect 
that the syscall does not exist and implement a fallback, which leads
to breakage like 'touch' not working anymore.

This is especially true for lenny running with a kernel from etch, and
will become more true with sid with a kernel from lenny as the glibc 
version increases.

This has been fixed in kernel 2.6.28, so kernels from etch, etchnhalf
and lenny are affected. The patch series below applies for all of 
them.
