[fedora-arm] Building RHEL/Fedora Kernels on ARM

[Gordan Bobic]

Hi,

I'm trying to build a RHEL6 kernel from src.rpm on ARM and I think I 
have it mostly sorted out, but it looks like the modules aren't getting 
signed and since they weren't signed from <module>.ko.unsigned 
<module>.ko the packaging part can't find the .ko files and the process 
fails at the end.

I added the configs for arm (Kirkwood), modified Makefile.config, and 
added a few minor changes to the spec file along with a few patches for 
various breakages in the RHEL kernel caused by either broken or 
incomplete patches applied there. I am also defining rhel to 1 so that 
the debug and signing are used.

At the end of the build process I get this:

A few hundred instances of this:

<stdin>: Assembler messages:
<stdin>:3: Error: junk at end of line, first unrecognized character is `,'

Immediately followed by this bit that looks OK (I think):

This is then followed by a line like this for every module that should 
be packaged:


cp: cannot stat `crypto/aes_generic.ko': No such file or directory
cp: cannot stat `crypto/ansi_cprng.ko': No such file or directory
cp: cannot stat `crypto/anubis.ko': No such file or directory
cp: cannot stat `crypto/arc4.ko': No such file or directory

Reading through the spec file, the last thing that happens before 
building the %{wigh_perftool} stuff is:

     make -s ARCH=$Arch %{oldconfig_target} > /dev/null
     make -s ARCH=$Arch V=1 %{?_smp_mflags} $MakeTarget %{?sparse_mflags}
     if [ "$Arch" != "s390" -o "$Flavour" != "kdump" ]; then
         make -s ARCH=$Arch V=1 %{?_smp_mflags} modules 
%{?sparse_mflags} || exit 1
     fi


Am I understanding this right?

Can anybody point me in the direction of where the problem might be WRT 
why the modules aren't getting signed? From what I can figure out there 
is no separate signing stage, it should all be done by "make modules", 
but for some reason it isn't happening. :(
