+Subject: [PATCH] linux-user: ARM: Ignore immediate value for svc in thumb mode
+
+When running in thumb mode, Linux doesn't evaluate the immediate value
+of the svc instruction, but instead just always assumes the syscall number
+to be in r7.
+
+This fixes executing go_bootstrap while building go for me.
