Subject: [PATCH] x86_64 irq: Use NR_IRQS not NR_IRQ_VECTORS
X-Git-Tag: v2.6.21-rc2~54
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e273d140d9d0c2c7941d97a6ace455113bb4ec63;p=linux-2.6

[PATCH] x86_64 irq: Use NR_IRQS not NR_IRQ_VECTORS

NR_IRQ_VECTORS is currently a compatiblity define set to NR_IRQs.
This patch updates the users of NR_IRQ_VECTORS to use NR_IRQs instead
so that NR_IRQ_VECTORS can be removed.

There is still shared code with arch/i386 that uses NR_IRQ_VECTORS
so we can't remove the #define just yet :(
