Subject: [PATCH 4/6] locking/atomic/x86: Merge x86_32 and x86_64 arch_atomic64_fetch_{and,or,xor}() functions
Date: Tue,  9 Apr 2024 12:03:55 +0200
Message-ID: <20240409100503.274629-5-ubizjak@gmail.com>
In-Reply-To: <20240409100503.274629-1-ubizjak@gmail.com>

Move the same definitions of arch_atomic64_fetch_{and,or,xor}() from
x86/include/asm/atomic64_32.h and x86/include/asm/atomic64_64.h
to the common place in arch/x86/include/asm/atomic.h

No functional changes intended.
