From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: To: Paul Mackerras From: Michael Ellerman Date: Sun, 26 Nov 2006 17:36:15 +1100 Subject: [PATCH] Provide dummy hard_irq_enable/disable() for PPC32 Message-Id: <20061126063616.A186067B22@ozlabs.org> Cc: linuxppc-dev@ozlabs.org, rutger@nospam.com List-Id: Linux on PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To allow arch/powerpc/kernel/crash.c to build on 32-bit we need a definition of hard_irq_disable(). 32-bit doesn't support the lazy interrupt disabling mechanism, so on 32-bit hard_irq_disable() is simply local_irq_disable(). Add a definition for hard_irq_enable() just for completeness. This allows (KEXEC=y && PPC32=y) to build again. Broken since d04c56f73c30a5e593202ecfcf25ed43d42363a2.
