      unix: update syscall numbers to 4.10 kernel · 21f2569f
      Joe Richey authored 
      The syscall numbers for Linux were out of date, so with the release of
the 4.10 kernel, now seemed like a reasonable time to update them. Note
that this change is mostly additive except that it removes some invalid
syscalls for arm, and it removes all constants that refer to either the
syscall base or total number of syscalls. Previous versions had only
removed some of them.

The updated syscall numbers were pulled directly from a header build
of the 4.10 kernel. This required some minor adjustements to the sysnum
generating perl script and is why the comments at the tops of the
generated files look slightly different. I could include the script I
used to do this, but right now it cannot generate the zerrors and ztypes
files.

      unix: add s390x support · 33267e03
      Michael Munday authored 
      This commit adds linux/s390x support to the unix package. It is
based on the changes made to the syscall package in
https://golang.org/cl/20961/. It also adds mkpost.go which is
used to cleanup the API generated by cgo -godefs.

The biggest departure that is made with the syscall package is
the use of the -fsigned-char flag to force signed chars. We
couldn't do this in the syscall package because of the need to
maintain compatibility with the gccgo implementation of the syscall
package (gccgo has supported s390x for a longer time than the Go
toolchain). The unix package does not have this constraint.

Using the -fsigned-char flag makes the API look more like the one
generated on amd64 and arm64 and also more consistent with itself
(the syscall package represents chars using both int8 and uint8
types, the sys package will only ever use int8). Unfortunately it
also means that applications transitioning from the syscall package
to the unix package will see a different API on s390x which might
be confusing. I think the tradeoff is worth it though.
