In 1e5834c38a22 ("Refactor Linux ipc_priv header") a different approach to passing __IPC_64 as zero was created. Hppa kernel ABI requires to pass __IPC_64 as zero since it does not set CONFIG_ARCH_WANT_IPC_PARSE_VERSION in the kernel. Checked on hppa-linux-gnu with some adjustments to avoid BZ#21016 (basically by removing hppa compat implementations and adjusting required headers). * sysdeps/unix/sysv/linux/hppa/ipc_priv.h: New file. --- ChangeLog | 4 ++++ sysdeps/unix/sysv/linux/hppa/ipc_priv.h | 21 +++++++++++++++++++++ 2 files changed, 25 insertions(+) create mode 100644 sysdeps/unix/sysv/linux/hppa/ipc_priv.h
