From c2e7a19827eec443a7cbe85e8d959052412d6dc3 Mon Sep 17 00:00:00 2001 From: Rohan McLure Date: Wed, 21 Sep 2022 16:55:50 +1000 Subject: powerpc: Use generic fallocate compatibility syscall The powerpc fallocate compat syscall handler is identical to the generic implementation provided by commit 59c10c52f573f ("riscv: compat: syscall: Add compat_sys_call_table implementation"), and as such can be removed in favour of the generic implementation. A future patch series will replace more architecture-defined syscall handlers with generic implementations, dependent on introducing generic implementations that are compatible with powerpc and arm's parameter reorderings.
