We have real overruns. We have ~2800 bytes of XSAVE (regisiter) state
mostly from AVX-512, and a 2048 byte MINSIGSTKSZ.

During signal entry, the kernel pushes data onto the normal userspace
stack. On x86, the data pushed onto the user stack includes XSAVE state,
which has grown over time as new features and larger registers have been
added to the architecture.
MINSIGSTKSZ is a constant provided in the kernel
