Fix sys/procfs.h pr_uid, pr_gid type (bug 23649).
As noted in
<https://sourceware.org/ml/libc-alpha/2018-09/msg00178.html>, glibc's
sys/procfs.h headers for microblaze, mips (n64), nios2 and riscv have
incorrect types for the pr_uid and pr_gid members of struct
elf_prpsinfo (as does the generic Linux version, but nothing uses
that).
This patch fixes those headers to use unsigned int. The generic Linux
version is also fixed, but I do *not* recommend making new
architectures use it yet. Rather, I think it should be reworked to
look more like a copy of the AArch64 version, but with a new
<bits/procfs.h> header included to provide register set definitions;
<bits/procfs.h> would then be architecture-specific while many
architectures could use the generic <sys/procfs.h>. This fix is
deliberately separate from any reworking to use a generic header more,
since it's possible there could be uses for backporting this fix but
not for backporting a subsequent cleanup.
Tested with build-many-glibcs.py. This of course doesn't provide much
validation of the structure layout; if the Linux kernel is fixed so
that "#include <linux/elfcore.h>" actually compiles with the headers
from "make headers_install" (and if the layout in both headers is
meant to be the same, whatever ABI we are building for), I have a test
that can be added to glibc to check the layout against that from the
Linux kernel.
[BZ #23649]
* sysdeps/unix/sysv/linux/microblaze/sys/procfs.h (struct
elf_prpsinfo): Use unsigned int for pr_uid and pr_gid.
* sysdeps/unix/sysv/linux/mips/sys/procfs.h (struct elf_prpsinfo):
Likewise.
* sysdeps/unix/sysv/linux/nios2/sys/procfs.h (struct
elf_prpsinfo): Likewise.
* sysdeps/unix/sysv/linux/riscv/sys/procfs.h (struct
elf_prpsinfo): Likewise.
* sysdeps/unix/sysv/linux/sys/procfs.h (struct elf_prpsinfo):
Likewise.
