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/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < git log --format=%s --max-count=1 3e22ed88f973d538104798edfa5140769483bce1 # < make -s -j 48 ARCH=arm64 O=/kisskb/build/powerpc-next_arm64-defconfig_arm64 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- defconfig # make -s -j 48 ARCH=arm64 O=/kisskb/build/powerpc-next_arm64-defconfig_arm64 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:27: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum arch/arm64/Makefile:40: LSE atomics not supported by binutils <stdin>:1335:2: warning: #warning syscall rseq not implemented [-Wcpp] Completed OK # rm -rf /kisskb/build/powerpc-next_arm64-defconfig_arm64 # Build took: 0:05:09.014602
