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.
Eliav Farber (2):
kexec: Consolidate machine_kexec_mask_interrupts() implementation
kexec: Prevent redundant IRQ masking by checking state before shutdown
