[ Upstream commit 592432862cc4019075a7196d9961562c49507d6f ] To check whether the CPU and kernel support the MTE features we want to test, we use an (emulated) CPU ID register read. However we only check against a very particular feature version (0b0010), even though the ARM ARM promises ID register features to be backwards compatible. While this could be fixed by using ">=" instead of "==", we should actually use the explicit HWCAP2_MTE hardware capability, exposed by the kernel via the ELF auxiliary vectors. That moves this responsibility to the kernel, and fixes running the tests on machines with FEAT_MTE3 capability.
