warning: symbol 'entry_flush' was not declared.
warning: symbol 'uaccess_flush' was not declared.
We found warnings above in arch/powerpc/kernel/setup_64.c by using
sparse tool.
Define 'entry_flush' and 'uaccess_flush' as static because they are not
referenced outside the file. Include asm/security_features.h in which
'rfi_flush' is declared.

Hi He Ying,
Thank you for this patch.
I'm not sure what the precise rules for Fixes are, but I wonder if this
should have:
Fixes: 9a32a7e78bd0 ("powerpc/64s: flush L1D after user accesses")
Fixes: f79643787e0a ("powerpc/64s: flush L1D on kernel entry")
Those are the commits that added the entry_flush and uaccess_flush
symbols. Perhaps one for rfi_flush too but I'm not sure what commit
introduced that.
Kind regards,
Daniel

Is that necessary for warning cleanups? I thought 'Fixes' tags are
needed only for
bugfix patches. Can someone tell me whether I am right?

It's not necessary to add a Fixes tag for a patch like this, but you can
add one if you think it's important that the fix gets backported.
I don't think the cleanups in this case are that important, so I
wouldn't bother with a Fixes tag.
