[Qemu-devel] [RISU PATCH v3 21/22] risu_reginfo_aarch64: limit SVE_VQ_MAX to current architecture

[Alex Bennée]

From: Richard Henderson <address@hidden>

The kernel headers optimistically assume it's going to grow but as we
are never going to use that many on current hardware we limit
SVE_VQ_MAX to what we will.
