Unexpected variation in SYS_ID_AA64MMFR0_EL1

Hello,
On an APQ8098-based system, for cores 4-7 (little cores?), the kernel prints:
[ 0.179055] CPU features: SANITY CHECK: Unexpected variation in SYS_ID_AA64MMFR0_EL1.
Boot CPU: 0x00000000001122, CPU4: 0x00000000101122
TGran16, [23:20]
Support for 16KB memory translation granule size:
0x1 Indicates that the 16KB granule is supported.
Since this is a pr_warn, I get the feeling something is not quite right.
Is there something to fix? Is it a problem that the big and little cores
don't support exactly the same granule sizes?
Regards.
