[POWERPC] Provide dummy hard_irq_enable/disable() for PPC32

mpe · paulusmack · commit 143db67af02c · 2006-12-04T20:41:27.000+11:00
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 d04c56f.
