Message-Id: <1201817440-5081-4-git-send-email-sam@ravnborg.org> Date: Thu, 31 Jan 2008 23:10:33 +0100 From: Sam Ravnborg <sam@...nborg.org> To: LKML <linux-kernel@...r.kernel.org>, Andrew Morton <akpm@...ux-foundation.org> Cc: Sam Ravnborg <sam@...nborg.org>, Gautham R Shenoy <ego@...ibm.com> Subject: [PATCH] cpu: fix section mismatch related to cpu_chain Fix following warnings: WARNING: o-x86_64/kernel/built-in.o(.text+0x36de9): Section mismatch in reference from the function take_cpu_down() to the variable .cpuinit.data:cpu_chain WARNING: o-x86_64/kernel/built-in.o(.text+0x36e86): Section mismatch in reference from the function _cpu_down() to the variable .cpuinit.data:cpu_chain WARNING: o-x86_64/kernel/built-in.o(.text+0x36ea9): Section mismatch in reference from the function _cpu_down() to the variable .cpuinit.data:cpu_chain WARNING: o-x86_64/kernel/built-in.o(.text+0x36f40): Section mismatch in reference from the function _cpu_down() to the variable .cpuinit.data:cpu_chain WARNING: o-x86_64/kernel/built-in.o(.text+0x36f8f): Section mismatch in reference from the function _cpu_down() to the variable .cpuinit.data:cpu_chain WARNING: o-x86_64/kernel/built-in.o(.text+0x370aa): Section mismatch in reference from the function unregister_cpu_notifier() to the variable .cpuinit.data:cpu_chain cpu_chain is used by unregister_cpu_notifier() that is used by the kvm module. So we can call the unregister_cpu_notifier() long after init completed. Drop the __cpuinitdata annotation to avoid freeing cpu_chain.
