From eda713e219c9a7d02b8263ab3fba44092e919b07 Mon Sep 17 00:00:00 2001 From: Baruch Siach Date: Thu, 19 Apr 2012 09:32:06 +0300 Subject: powerpc: fix build when CONFIG_BOOKE_WDT is enabled Commit ae3a197e (Disintegrate asm/system.h for PowerPC) broke build of assembly files when CONFIG_BOOKE_WDT is enabled as follows: AS arch/powerpc/lib/string.o /home/baruch/git/stable/arch/powerpc/include/asm/reg_booke.h: Assembler messages: /home/baruch/git/stable/arch/powerpc/include/asm/reg_booke.h:19: Error: Unrecognized opcode: `extern' /home/baruch/git/stable/arch/powerpc/include/asm/reg_booke.h:20: Error: Unrecognized opcode: `extern' Since setup_32.c is the only user of the booke_wdt configuration variables, move the declarations there.

This in turn makes us read the HW state and update the irq desc accordingly.
