+Subject: [PATCH] sparc64: make string buffers large enough
+
+My static checker complains that if "lvl" is ULONG_MAX (this is 64 bit)
+then some of the strings will overflow.  I don't know if that's possible
+but it seems simple enough to make the buffers slightly larger.

+Subject: m68k: Use conventional function parameters for do_sigreturn
+
+Create conventional stack parameters for the calls to do_sigreturn and
+do_rt_sigreturn. The current C code for do_sigreturn and do_rt_sigreturn
+dig into the stack to create local pointers to the saved switch stack
+and the pt_regs structs.
+
+The motivation for this change is a problem with non-MMU targets that
+have broken signal return paths on newer versions of gcc. It appears as
+though gcc has determined that the pointers into the saved stack structs,
+and the saved structs themselves, are function parameters and updates to
+them will be lost on function return, so they are optimized away. This
+results in large parts of restore_sigcontext() and mangle_kernel_stack()
+functions being removed. Of course this results in non-functional code
+causing kernel oops. This problem has been observed with gcc version
+5.2 and 5.3, and probably exists in earlier versions as well.
+
+Using conventional stack parameter pointers passed to these functions has
+the advantage of the code here not needing to know the exact details of
+how the underlying entry handler layed these structs out on the stack.
+So the rather ugly pointer setup casting and arg referencing can be
+removed.
+
+The resulting code after this change is a few bytes larger (due to the
+overhead of creating the stack args and their tear down). Not being hot
+paths I don't think this is too much of a problem here.
+
+An alternative solution is to put a barrier() in the do_sigreturn() code,
+but this doesn't feel quite as clean as this solution.
+
+This change has been compile tested on all defconfigs, and run tested on
+Atari (through aranym), ColdFire with MMU (M5407EVB) and ColdFire with
+no-MMU (QEMU and M5208EVB).
