exynos9810 problem

[Timen]

I'm unsure this has already been integrated but for certain Exynos 9810 devices on a specific android version it will report to support certain instructions but only some of the cores actually do as discussed in this LLVM post https://reviews.llvm.org/D114523

Big.LITTLE Heterogeneous architectures, as described by ARM [1],
require that the instruction set architecture of the big and little
cores be compatible. However, the Samsung Exynos 9810 is known to
have different ISAs in its core.
According to [2], some cores are ARMv8.2 and others are ARMv8.0.

Since LSE is for ARMv8.1 and later, it should be disabled
for this broken CPU.

Ah yes, exactly! Sorry I wasn't able to find it, and figure doesn't hurt to double check 👍
