Subject: [RFC PATCH v2 03/11] powerpc: move set_soft_enabled()
Date: Mon, 1 Aug 2016 00:36:21 +0530 [thread overview]
Message-ID: <1469991989-28409-4-git-send-email-maddy@linux.vnet.ibm.com> (raw)
In-Reply-To: <1469991989-28409-1-git-send-email-maddy@linux.vnet.ibm.com>
Move set_soft_enabled() from powerpc/kernel/irq.c to
asm/hw_irq.c. this way updation of paca->soft_enabled
can be forced wherever possible.
