From 5ceb1a04187553e08c6ab60d30cee7c454ee139a Mon Sep 17 00:00:00 2001 From: Matt Fleming Date: Sun, 2 Nov 2008 22:23:13 +0000 Subject: [PATCH] x86: HPET: enter hpet_interrupt_handler with interrupts disabled Some functions that may be called from this handler require that interrupts are disabled. Also, combining IRQF_DISABLED and IRQF_SHARED does not reliably disable interrupts in a handler, so remove IRQF_SHARED from the irq flags (this irq is not shared anyway).
