There is nothing to do for Linaro. The fix is both in the 2.23 branch and trunk. Afaik, Linaro doesn't support the HJL binutils releases.

This appears to be related to the following bug report for binutils: http://sourceware.org/ml/binutils/2012-09/msg00128.html
I'm compiling the kernel for PandaBoard
Any ideas for work-arounds or fixes for this? Note that the ldralt instruction doesn't actually appear in copy_template.S (maybe it's coming from a macro?) -- Tim
