[PATCH v6 1/6] powerpc: make llseek 32bit-only.

From: Michal Suchanek
Date: Fri Aug 30 2019 - 14:58:09 EST


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 interface 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")
