We can free the page table cache pages on task exit # because they only cache the userspace page tables and kernel threads # should not access user space addresses. # # The mapping for kernel threads itself is maintained in init_mm and # page table cache for that is attached to init_mm. # # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # Reviewed-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> # [mpe: Merge change log additions from Aneesh] # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 3e22ed88f973d538104798edfa5140769483bce1 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc40x_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ppc40x_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc40x_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.
