+# WARNING: nasty hack.  Because sysnum.h produces thumb syscall
+# numbers when compiled in thumb mode the arm assembler (which is arm
+# even in thumb mode) needs to write the OS syscall base back into
+# the swi calls.  This is done here just by orring in the correct
+# value.  This is a hack - it might be better to add a define to
+# sysnum.h to force it to output arm (not thumb) values on demand -
+# but this hack is fairly safe (rmk would have to change the syscall
+# base, this seems unlikely).
+#
+# The patch also fixes up the .align directives to '2' (i.e. a multiple
+# of 4) not '4' (a multiple of 16 - apparently an error since it seems
+# to be unnecessary, there is no advantage here in cache line alignment).
