compile warning

compile warning

[Sergej Stepanov]

Hello!

I have at compile time the following warning:

WARNING: vmlinux.o(.text+0x10f5c): Section mismatch: reference
to .init.text:cpm_muram_init (between 'cpm2_reset' and
'cpm2_smc_clk_setup')

Could it make some problem?

Thanks.

It should be fixed, but its highly unlikely you'll see a problem  
unless you start trying to build core parts of the CPM code as modules.

we have no modules for CPM.
Fix it i could with :

diff --git a/arch/powerpc/sysdev/cpm2_common.c b/arch/powerpc/sysdev/cpm2_common.c
index f8a621e..f507ada 100644
--- a/arch/powerpc/sysdev/cpm2_common.c
+++ b/arch/powerpc/sysdev/cpm2_common.c
@@ -61,7 +61,7 @@ cpm2_map_t __iomem *cpm2_immr;
 					   of space for CPM as it is larger
 					   than on PQ2 */
 
-void
+void __init
 cpm2_reset(void)
 {
 #ifdef CONFIG_PPC_85xx

------------------
I am not sure it is ok.

But i have other 2 warnings (no modules).

WARNING: vmlinux.o(.exit.text+0x5da): Section mismatch: reference to .init.data:of_platform_serial_driver (between 'of_platform_serial_exit' and 'phy_exit')
WARNING: vmlinux.o(.exit.text+0x5e2): Section mismatch: reference to .init.data:of_platform_serial_driver (between 'of_platform_serial_exit' and 'phy_exit')
 
Regards.

Yes, this looks good.

This seems to be my fault. I'll try to come up with the right fix.
