+Subject: [PATCH] linux-user: Tag vsx with ieee128 fpbits
+
+In OE we need this for ppc64le usermode to work since we generate 128bit
+long doubles and glibc 2.34 is now checking for this in hwcaps at
+runtime and failing to run the binary if machine does not support 128bit
+IEEE fp
+
+Fixes
+Fatal glibc error: CPU lacks float128 support (POWER 9 or later required)
+
+Upstream-Status: Pending
