Subject: [PATCH v4 0/2] Improve interrupt handling during machine kexec
Date: Fri, 29 Nov 2024 11:31:17 +0000	[thread overview]
Message-ID: <20241129113119.26669-1-farbere@amazon.com> (raw)

This patch series focuses on improving the machine_kexec_mask_interrupts()
function by consolidating its implementation and optimizing its behavior to
avoid redundant interrupt masking.

Patch Summary:
[PATCH v4 1/2] Move machine_kexec_mask_interrupts() to kexec_core.c,
               removing duplicate architecture-specific implementations.
[PATCH v4 2/2] Refine machine_kexec_mask_interrupts() to avoid re-masking
               already-masked interrupts, resolving specific warnings
               triggered in GPIO IRQ flows.

Changes between v3 and v4:
 - Add missing <linux/irqdesc.h> and <linux/irq.h> includes.

  kexec: Prevent redundant IRQ masking by checking state before shutdown
