Subject: [PATCH v3 11/11] accel/tcg: Remove do_interrupt_locked() callback
Date: Wed, 2 Sep 2026 17:20:42 +0200 [thread overview]
Message-ID: <20260902152044.31291-12-philmd@oss.qualcomm.com> (raw)
In-Reply-To: <20260902152044.31291-1-philmd@oss.qualcomm.com>
All targets now manage their own BQL locking via do_interrupt(),
making the do_interrupt_locked() hook unnecessary. Remove it to
simplify the TCGCPUOps interface.
