Subject: powerpc: fix build when CONFIG_BOOKE_WDT is enabled
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=eda713e219c9a7d02b8263ab3fba44092e919b07;p=linux.git

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.
