| |
3.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vladimir Zapolskiy <vladimir.zapolskiy@nokia.com>
commit 55205c916e179e09773d98d290334d319f45ac6b upstream.
This change fixes a linking problem, which happens if oprofile is selected to be compiled as built-in:
`oprofile_arch_exit' referenced in section `.init.text' of arch/arm/oprofile/built-in.o: defined in discarded section `.exit.text' of arch/arm/oprofile/built-in.o
The problem is appeared after commit 87121ca504, which introduced oprofile_arch_exit() calls from __init function. Note that the aforementioned commit has been backported to stable branches, and the problem is known to be reproduced at least with 3.0.13 and 3.1.5 kernels.
