[PATCH] ppc32: Fix warning on CONFIG_PPC32 && CONFIG_6xx

[PATCH] ppc32: Fix warning on CONFIG_PPC32 && CONFIG_6xx

[Tom Rini]

In the *ppos cleanups, proc_dol2crvec was updated, but the prototype
found at the top of kernel/sysctl.h was not, generating warning.  This
corrects the prototype to match the code.

(I'm gonna take a stab at moving these into arch/ppc shortly)

The alternative to this, which I can resend after 2.6.8 if you'd prefer,
is to move both of these sysctls into arch/ppc where they belong.
