Subject: [PATCH v3 03/17] y2038: ia64: Remove unneeded ipc uapi header files
Date: Thu, 19 Apr 2018 16:37:23 +0200	[thread overview]
Message-ID: <20180419143737.606138-4-arnd@arndb.de> (raw)
In-Reply-To: <20180419143737.606138-1-arnd@arndb.de>

The ia64 ipcbuf/msgbuf/sembuf/shmbuf header files are all identical
to the version from asm-generic.

This patch removes the files and replaces them with 'generic-y'
statements as part of the y2038 changes. While ia64 no longer has
a compat mode and doesn't need the file any more, it seem nicer
to clean this up anyway.
