The _end symbol in a kernel build is not correct. When building the 'mpc85xx_defconfig' on a v2.6.30 kernel the _end symbol is: vmlinux:00001000 A _end Building this same kernel w/gcc4.3 & binutils 2.18.50.0.9-8.fc10 from FC10 produce: vmlinux:c0599000 A _end It appears to be some issue with the ALIGN() directive in the linker script (arch/powerpc/kernel/vmlinux.lds) before the _end. If we remove the ALIGN directive the _end symbol has a reasonable value of: vmlinux:c05d3018 A _end
Hi Kumar, I assume that this problem is the same as the one that you have reported on the bug-binutils mailing list: http://lists.gnu.org/archive/html/bug-binutils/2009-07/msg00059.h It sounds like you have found a workaround for the problem. Do you still want this bug report left open ? Cheers Nick
Yes I'd like it still open. While we have a workaround I dont consider it sufficient since the fact that we have a chicken/egg scenario here. Older kernel linker scripts aren't going to know about all sections and thus have orphans. If newer binutils are going to place orphan sections at places that break things like _end we have an issue.
Hi Kumar, In which case, please could you put together a small testcase that reproduces the problem so that I can investigate further. Cheers Nick
It looks like Alan Morda posted a patch and has applied it to mainline binutils CVS for this issue. Do you mind back porting that to the fedora binutils and making a bug fix release The commit info is here: http://sourceware.org/ml/binutils-cvs/2009-07/msg00069.html

Thanks. Any ability to get an updated package for fc11? - k
At Josh Boyer's recommendation I'm reopening this and pointing out that it was against F11.
