Message-Id: <1365638712-1028578-3-git-send-email-arnd@arndb.de> Date: Thu, 11 Apr 2013 02:04:44 +0200 From: Arnd Bergmann <arnd@...db.de> To: linux-arm-kernel@...ts.infradead.org Cc: linux-kernel@...r.kernel.org, Kukjin Kim <kgene.kim@...sung.com>, linux-samsung-soc@...r.kernel.org, Arnd Bergmann <arnd@...db.de> Subject: [PATCH 02/30] ARM: exynos: prepare for sparse IRQ When we enable CONFIG_SPARSE_IRQ, we have to set the value of NR_IRQS in the machine_desc for legacy IRQ domains, and any file referring to the number of interrupts or a specific number must include the mach/irqs.h header file explicitly.
