Subject: [PATCH v4 04/16] y2038: ia64: Remove unneeded ipc uapi header files
Date: Wed, 25 Apr 2018 17:05:54 +0200	[thread overview]
Message-ID: <20180425150606.954771-4-arnd@arndb.de> (raw)
In-Reply-To: <20180425132242.1500539-1-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.
