This patchset fixes a handful of minor bugs in our SME implementation:
one spotted by Coverity, one raised as a Gitlab issue, and a couple
that I just noticed in passing while I was working with the code.

thanks

Peter Maydell (4):
  target/arm: Don't assert for 128-bit tile accesses when SVL is 128
  target/arm: Fix UMOPA/UMOPS of 16-bit values
  target/arm: Avoid shifts by -1 in tszimm_shr() and tszimm_shl()
  target/arm: Ignore SMCR_EL2.LEN and SVCR_EL2.LEN if EL2 is not enabled
