Subject: arm64/signal: Always allocate SVE signal frames on SME only systems
From: Mark Brown <broonie@xxxxxxxxxx>
commit f26cd7372160da2eba31061d7943348ab9f2c01d upstream.
Currently we only allocate space for SVE signal frames on systems that
support SVE, meaning that SME only systems do not allocate a signal frame
for streaming mode SVE state. Change the check so space is allocated if
either feature is supported.
