I don't have a strong preference.
But, for someone who is using log levels to reduce the kernel log
details, the below fpu-specific messages probably don't seem to be in
priority order.
pr_info("x86/fpu: XSAVE disabled\n");
pr_warn("x86/fpu: init_fpstate buffer too small (%zu < %d)\n",
pr_err("x86/fpu: Both APX/MPX present in the CPU's xstate features:
0x%llx.\n",
pr_err("x86/fpu: xfeatures modified from 0x%016llx to 0x%016llx during
init\n",
pr_err("x86/fpu: FP/SSE not present amongst the CPU's xstate features:
0x%llx.\n",
"XSAVE disabled" seems most important, with the rest just being internal
details. Maybe it's just me... Feel free to ignore unless someone else
chimes in.
