From a4c1887d4c1462b0ec5a8989f8ba3cdd9057a299 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Tue, 3 Oct 2017 19:25:29 +0100 Subject: locking/arch: Remove dummy arch_{read,spin,write}_lock_flags() implementations The arch_{read,spin,write}_lock_flags() macros are simply mapped to the non-flags versions by the majority of architectures, so do this in core code and remove the dummy implementations. Also remove the implementation in spinlock_up.h, since all callers of do_raw_spin_lock_flags() call local_irq_save(flags) anyway.
