[PATCH 0/4] aarch64: Add SME support

[Szabolcs Nagy]

Most of the SME (Scalable Matrix Extension) runtime support is
in libgcc, a bit of that has to be repeated in the libc so we
don't depend on libgcc to handle the ZA register state in
longjmp.

Szabolcs Nagy (4):
  aarch64: Add SME runtime support
  aarch64: Add longjmp support for SME
  aarch64: Add setcontext support for SME
  aarch64: Add longjmp test for SME
