Subject: [PATCH 01/58] jsm: IRQ handlers doesn't need to have IRQ_DISABLED enabled

From: Breno Leitão <leitao@...ux.vnet.ibm.com>

Currently jsm is showing the following message when loaded:

IRQ 432/JSM: IRQF_DISABLED is not guaranteed on shared IRQs

It's because the request_irq() is called using IRQF_DISABLED
and IRQF_SHARED.
Actually there is no need to use IRQF_DISABLED in this driver.
