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.
Fixes: 85ed24dad290 ("arm64/sme: Implement streaming SVE signal handling")
