This breaks ppc40x_defconfig & 40x/ep405_defconfig with:
arch/powerpc/mm/40x_mmu.c: In function 'mmu_mapin_ram':
arch/powerpc/mm/40x_mmu.c:113:20: error: lvalue required as left operand of assignment
arch/powerpc/mm/40x_mmu.c:114:20: error: lvalue required as left operand of assignment
arch/powerpc/mm/40x_mmu.c:115:20: error: lvalue required as left operand of assignment
arch/powerpc/mm/40x_mmu.c:116:20: error: lvalue required as left operand of assignment
arch/powerpc/mm/40x_mmu.c:128:18: error: lvalue required as left operand of assignment
Which is mainly:
pmd_val(*pmdp++) = val;
The obvious patch to use pmd_set() doesn't work, I think because there's no
pmd_set() defined for 32-bit nohash?
cheers
