SME2 expands on SME by adding a predicate register of 512 bits named ZT0. At a high level, this series does the following: - Adds support for the ZT0 register and adds a new target description feature for it. - Core file support (depends on binutils patches). - Signal frame context support. - Native Linux handling of the new NT_ARM_ZT register set. This series depends on the SME series, and should be applied on top of that one.
