+Subject: [PATCH] x86-64: Optimize load of all bits set into ZMM register [BZ
+ #28252]
+
+Optimize loads of all bits set into ZMM register in AVX512 SVML codes
+by replacing
+
+	vpbroadcastq .L_2il0floatpacket.16(%rip), %zmmX
+
+and
+
+	vmovups   .L_2il0floatpacket.13(%rip), %zmmX
+
+with
+	vpternlogd $0xff, %zmmX, %zmmX, %zmmX
+
+This fixes BZ #28252.
