parisc: Drop the HP-UX ENOSYM and EREMOTERELEASE error codes

2023-12-08T07:52:20Z

commit e5f3e299a2b1e9c3ece24a38adfc089aef307e8a upstream. Those return codes are only defined for the parisc architecture and are leftovers from when we wanted to be HP-UX compatible. They are not returned by any Linux kernel syscall but do trigger problems with the glibc strerrorname_np() and strerror() functions as reported in glibc issue #31080. There is no need to keep them, so simply remove them.

parisc: Drop architecture-specific ENOTSUP define

2018-08-13T07:30:41Z

parisc is the only Linux architecture which has defined a value for ENOTSUP. All other architectures #define ENOTSUP as EOPNOTSUPP in their libc headers. Having an own value for ENOTSUP which is different than EOPNOTSUPP often gives problems with userspace programs which expect both to be the same. One such example is a build error in the libuv package, as can be seen in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900237. Since we dropped HP-UX support, there is no real benefit in keeping an own value for ENOTSUP. This patch drops the parisc value for ENOTSUP from the kernel sources. glibc needs no patch, it reuses the exported headers. Signed-off-by: Helge Deller

tools include arch: Grab a copy of errno.h for arch's supported by perf

2018-01-23T12:51:37Z

For each arch in tools/perf/arch, grab a copy of errno.h. This is a pre-req to generate an architecture specific mapping of errno numbers to their names. This errno mapping can be used by perf trace to support cross-architecture trace reports and to get rid of the audit-libs dependency.
