+Subject: [PATCH] Replace 'struct ucontext' with 'ucontext_t' type
+
+glibc used to have:
+
+ typedef struct ucontext { ... } ucontext_t;
+
+glibc now has:
+
+ typedef struct ucontext_t { ... } ucontext_t;
+
+(See https://sourceware.org/bugzilla/show_bug.cgi?id=21457
+ for detail and rationale for the glibc change)
+
+However, QEMU used "struct ucontext" in declarations. This is a
+private name and compatibility cannot be guaranteed. Switch to
+only using the standardized type name.
