Message-Id: <1445706156-20203-1-git-send-email-yu.c.chen@intel.com> Date: Sun, 25 Oct 2015 01:02:36 +0800 From: Chen Yu <yu.c.chen@...el.com> To: rjw@...ysocki.net, lenb@...nel.org Cc: rui.zhang@...el.com, lv.zheng@...el.com, linux-acpi@...r.kernel.org, linux-kernel@...r.kernel.org, linux-pm@...r.kernel.org, Chen Yu <yu.c.chen@...el.com>, <stable@...r.kernel.org> Subject: [PATCH 2/3][v2] ACPI: Using correct irq when waiting for events When system is waiting for GPE/fixed event handler to finish, it uses the acpi_gbl_FADT.sci_interrupt directly. However, we should use mapped irq returned by acpi_gsi_to_irq for synchronize_hardirq.
