+# Before version 2.6, linux had separate 32-bit and 64-bit MIPS ports,
+# each with its own set of headers. The ports were merged for 2.6 and
+# this merged port defines the syscalls in a slightly different way.
+# There are therefore three sets of headers that we need to consider:
+#
+# (1) Headers from the separate 32-bit MIPS port. They just define
+# a single list of __NR macros.
+#
+# (2) Headers from the separate 64-bit MIPS port. They unconditionally
+# define syscalls for all three ABIs, with o32 syscalls prefixed
+# by __NR_O32, n32 syscalls prefixed by __NR_N32 and n64 syscalls
+# prefixed by plain __NR.
+#
+# (3) Headers from the combined port. They use the _RISCV_SIM macro to
+# define the right set of syscalls for the current ABI. The syscalls
+# themselves have no special ABI prefix, but the headers also define:
+#
+# __NR_O32_Linux{,_syscalls}
+# __NR_N32_Linux{,_syscalls}
+# __NR_64_Linux{,_syscalls}
+#
+# In case (1) we just want a simple list of SYS_* macros. In cases (2)
+# and (3) we want a file that will work for all three ABIs, regardless
+# of which ABI we are currently using. We also want the file to work
+# if the user later moves from (2) to (3). Thus the file we create
+# for (2) and (3) has the form:
+#
+# #if _RISCV_SIM == _ABIN32
+# # ifdef __NR_N32_open
+# # define SYS_n32syscall1 __NR_N32_n32syscall1
+# # ...

+# # ...
+# # else
+# # define SYS_o32syscall1 __NR_o32syscall1
+# # ...
+# # endif
+# #endif
+#
+# Here, __NR_N32_open and __NR_O32_open are used to detect case (2)
+# over case (3). The n64 SYS_* macros can always use the normal
