    Subject[PATCH AUTOSEL 5.6 039/606] powerpc/32s: Fix build failure with CONFIG_PPC_KUAP_DEBUG
    Date
    From: Christophe Leroy <christophe.leroy@c-s.fr>

    commit 4833ce06e6855d526234618b746ffb71d6612c9a upstream.

    gpr2 is not a parametre of kuap_check(), it doesn't exist.

    Use gpr instead.
