If you prefer next patch for fixes, then this one can be squashed into patch 3 which drops the PPC32 hacked definition of KERN_VIRT_START Christophe > Cc: stable@vger.kernel.org > Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> > --- > arch/powerpc/mm/ptdump/ptdump.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/arch/powerpc/mm/ptdump/ptdump.c b/arch/powerpc/mm/ptdump/ptdump.c > index 6a88a9f585d4..3ad64fc11419 100644 > --- a/arch/powerpc/mm/ptdump/ptdump.c > +++ b/arch/powerpc/mm/ptdump/ptdump.c > @@ -27,7 +27,7 @@ > #include "ptdump.h" > > #ifdef CONFIG_PPC32 > -#define KERN_VIRT_START PAGE_OFFSET > +#define KERN_VIRT_START 0 > #endif > > /* >

Commit 453d87f6a8ae ("powerpc/mm: Warn if W+X pages found on boot") wrongly changed KERN_VIRT_START from 0 to PAGE_OFFSET, leading to a shift in the displayed addresses. Lets revert that change to resync walk_pagetables()'s addr val and pgd_t pointer for PPC32.
