+Subject: [PATCH] x86/crtools: do not error when YMM is missing
+
+for Intel Apollo Lake SOC, its cpuinfo and fpu features:
+cpu: x86_family 6 x86_vendor_id GenuineIntel x86_model_id Intel(R) Celeron(R) CPU J3455 @ 1.50GHz
+cpu: fpu: xfeatures_mask 0x11 xsave_size 1088 xsave_size_max 1088 xsaves_size 704
+cpu: fpu: x87 floating point registers     xstate_offsets      0 / 0      xstate_sizes    160 / 160
+
+this CPU doesn't have AVX registers, YMM feature.
+
+when CRIU runs on this CPU, it will report dump error:
+Dumping GP/FPU registers for 4888
+Error (criu/arch/x86/crtools.c:362): x86: Corruption in XFEATURE_YMM area (expected 64 but 0 obtained)
+Error (criu/cr-dump.c:1278): Can't infect (pid: 4888) with parasite
+
+that's because x86/crtools.c will still valid YMM xsave frame, thus fail to dump.
+
+bypass unsupported feature, to make CRIU runs this kinds of CPUs.
