In radix mode, this is # exception is not an SLB miss, rather it signals that the EA is outside # the range translated by any page table. # # The commit lost the radix feature alternate code patch, which can # cause faults to some EAs to kernel BUG at arch/powerpc/mm/slb.c:639! # # The original radix code would send faults to slb_miss_large_addr, # which would end up faulting due to slb_addr_limit being 0. This patch # sends radix directly to do_bad_slb_fault, which is a bit clearer. # # Fixes: 48e7b7695745 ("powerpc/64s/hash: Convert SLB miss handlers to C") # Cc: stable@vger.kernel.org # v4.20+ # Reported-by: Anton Blanchard <anton@samba.org> # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # Reviewed-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 7100e8704b61247649c50551b965e71d168df30b # < make -s -j 48 ARCH=sparc64 O=/kisskb/build/powerpc-fixes_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- defconfig # make -s -j 48 ARCH=sparc64 O=/kisskb/build/powerpc-fixes_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- <stdin>:1478:2: warning: #warning syscall pidfd_send_signal not implemented [-Wcpp] <stdin>:1481:2: warning: #warning syscall io_uring_setup not implemented [-Wcpp] <stdin>:1484:2: warning: #warning syscall io_uring_enter not implemented [-Wcpp] <stdin>:1487:2: warning: #warning syscall io_uring_register not implemented [-Wcpp] WARNING: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned.
