We missed # the fact that for 32 bit platforms we did call the 'dtor' early. Drop the extra # call for pgtable_page_dtor. We remove the call from __pte_free_tlb so that we # do the page table free and 'dtor' call together. This should help when we # switch these platforms to pte fragments. # # Fixes: 667416f38554 ("powerpc/mm: Fix kernel crash on page table free") # Reported-by: Christophe Leroy # Signed-off-by: Aneesh Kumar K.V # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 941c06d58503b9f2718b20bc45ee7f1d701a1e1e # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc44x_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ppc44x_defconfig # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc44x_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/net/Makefile:24: CC cannot link executables.
