From 3d1b5e206a4f0ce46f2aa138590738c5d8e118ac Mon Sep 17 00:00:00 2001 From: Milton Miller Date: Tue, 24 May 2011 20:34:17 +0000 Subject: [PATCH] powerpc/irq: Always free duplicate IRQ_LEGACY hosts Since kmem caches are allocated before init_IRQ as noted in 3af259d155 (powerpc: Radix trees are available before init_IRQ), we now call kmalloc in all cases and can can always call kfree if we are asked to allocate a duplicate or conflicting IRQ_HOST_MAP_LEGACY host.
