Subject: [PATCH v5 1/5] powerpc: make llseek 32bit-only.
Date:   Fri, 30 Aug 2019 00:28:36 +0200
Message-Id: <5ce0aa18e5003ab4f6d390d96c569334523d0230.1567117050.git.msuchanek@suse.de>

Precedence: bulk

The llseek syscall is not built in fs/read_write.c when !64bit && !COMPAT
With the syscall marked as common in syscall.tbl build fails in this
case.

The llseek inteface does not make sense on 64bit and it is explicitly
described as 32bit interface. Use on 64bit is not well-defined so just
drop it for 64bit.

Fixes: caf6f9c8a326 ("asm-generic: Remove unneeded
__ARCH_WANT_SYS_LLSEEK macro")
