Build breakage on powerpc with 2.6.24-rc6-mm1

Build breakage on powerpc with 2.6.24-rc6-mm1

[Balbir Singh]

Hi,

I see the following error with the iseries_veth driver in 2.6.24-rc6-mm1

drivers/net/iseries_veth.c: In function ‘veth_init_connection’:
drivers/net/iseries_veth.c:818: warning: unused variable ‘rc’
drivers/net/iseries_veth.c: In function ‘veth_probe_one’:
drivers/net/iseries_veth.c:1086: error: ‘veth_port_ktypeq’ undeclared
(first use in this function)
drivers/net/iseries_veth.c:1086: error: (Each undeclared identifier is
reported only once
drivers/net/iseries_veth.c:1086: error: for each function it appears
in.)
make[2]: *** [drivers/net/iseries_veth.o] Error 1
make[1]: *** [drivers/net] Error 2
make: *** [drivers] Error 2

Here's a patch, compile tested to fix the compilation problem


Remove unused variable rc and fix a typo, veth_port_type was called
veth_port_typeq

Yeah, that would be
gregkh-driver-kobject-convert-drivers-net-iseries_vethc-to-use-kobject_init-add_ng.

Hi Greg, do you even build with your patches applied?

Hopefully Greg will fix his original patch before it reaches Linus.

Thanks for the report, sorry for the typos, I'll fix up my patch.

For the power architecture, no, I do not.  I used to, but my cross-build
box died and I haven't taken the time to set it all up again.  For i386
and x86-64 I do build everything, and as that's 99% of the users, it's
usually fine :)

I did start to try to get a s390 cross-build working, but ran out of
time a week or so ago...

I will do that.

Crosstool makes it really easy. It's demo-powerpc-970.sh will build a
toolchain that can build both 32- and 64-bit powerpc kernels. It's got
a demo-s390.sh as well, but I haven't tried that one myself.
