Hi Randy,
It's probably a bug fix that unveils the link errors.

Hi,
I suspect that it's more of an invalid .config file.
How do you generate the .config files? or is it a defconfig?
Yes, I have seen this build error, but I was able to get around it
by modifying the .config file. That's why I suspect that it may be
an invalid .config file.
thanks.

the config file was generated by "make ARCH=sh allmodconfig"

Can you share the fix steps? We'll take a look at it.

Hi,
For this build error:
>> arch/sh/kernel/cpu/sh2/clock-sh7619.o:(.data+0x1c): undefined reference to `followparent_recalc'
the problem is with CONFIG_COMMON_CLK. The COMMON_CLK framework does not
provide this API. However, in arch/sh/boards/Kconfig, COMMON_CLK is always
selected by SH_DEVICE_TREE. By disabling SH_DEVICE_TREE, the build
succeeds.

Thanks for the explanation, It seems SH_DEVICE_TREE was enabled by
allmodconfig.
does it mean it's a problem of allmodconfig? we thought kernel could be
built successfully.

I think that there are multiple $arch + boards/platforms that are very
board-specific where allmodconfig doesn't make sense, but that's mostly an
opinion. I haven't tried to prove it.
