+Subject: [PATCH] Fix build for no-MMU targets
+
+Commit 7488ce9e23f1 ("Check whether PTRACE_GET_SYSCALL_INFO is supported
+by the kernel") added a fork() call in test_ptrace_get_syscall_info()
+which is included in the main strace executable code. Although the
+test_ptrace_get_syscall_info() routine is not called on no-MMU targets,
+the compiler can't optimize it out because it is a global symbol. So
+build for no-MMU targets currently fails:
+
+strace-ptrace_syscall_info.o: In function `test_ptrace_get_syscall_info':
+ptrace_syscall_info.c:(.text+0x1c): undefined reference to `fork'
+
+Make the test_ptrace_get_syscall_info() definition depend on HAVE_FORK
+to fix that.

+Subject: [PATCH] Fix build for mips targets
+
+Commit 917c2ccf3a67 ("Refactor stack pointers") removed
+linux/mips/arch_regs.h that defines mips_REG_* macros and struct
+mips_regs. These symbols are referenced in mips code. Restore
+arch_regs.h to fix the build failure:
+
+syscall.c: In function 'decode_syscall_subcall':
+syscall.c:370:7: error: 'mips_REG_SP' undeclared (first use in this function)
