Subject: [PATCH v2 2/3] timers: Use __raise_softirq_irqoff() to raise the softirq.
From: Sebastian Andrzej Siewior <[email-masked]>
Date: Wed, 23 Oct 2024 13:02:37 +0200

As an optimisation use __raise_softirq_irqoff() to raise the softirq.
This is always called from an interrupt handler, interrupts are already
disabled so it can be reduced to just or set softirq flag and let
softirq be invoked on return from interrupt.

Use __raise_softirq_irqoff() to raise the softirq.
