Subject: [PATCH v3 03/10] irq: add irq__get_nr_allocated_lines
Date: Wed, 17 Jun 2015 12:21:54 +0100	[thread overview]
Message-ID: <1434540121-21283-4-git-send-email-andre.przywara@arm.com> (raw)
In-Reply-To: <1434540121-21283-1-git-send-email-andre.przywara@arm.com>

From: Marc Zyngier <marc.zyngier@arm.com>

The ARM GIC emulation needs to be told the number of interrupts
it has to support. As commit 1c262fa1dc7bc ("kvm tools: irq: make
irq__alloc_line generic") made the interrupt counter private,
add a new accessor returning the number of interrupt lines we've
allocated so far.
