There's a simple merge conflict in the Documentation/features/debug/KASAN/arch-support.txt The following changes since commit bebc6082da0a9f5d47a1ea2edc099bf671058bd4: Linux 4.14 (2017-11-12 10:46:13 -0800) are available in the git repository at: git://github.com/jcmvbkbc/linux-xtensa.git tags/xtensa-20180129 for you to fetch changes up to ca47480921587ae30417dd234a9f79af188e3666: xtensa: fix futex_atomic_cmpxchg_inatomic (2018-01-05 15:55:59 -0800) ---------------------------------------------------------------- Xtensa improvements for v4.16: - add SSP support; - add KASAN support; - improvements to xtensa-specific assembly: - use ENTRY and ENDPROC consistently; - clean up and unify word alignment macros; - clean up and unify fixup marking; - use 'call' instead of 'callx' where possible; - various cleanups: - consiolidate kernel stack size related definitions; - replace #ifdef'fed/commented out debug printk statements with pr_debug; - use struct exc_table instead of flat array for exception handling data; - build kernel with -mtext-section-literals; simplify xtensa linker script; - fix futex_atomic_cmpxchg_inatomic. ---------------------------------------------------------------- Arnd Bergmann (1): xtensa: shut up gcc-8 warnings Max Filippov (20): xtensa: add -mno-serialize-volatile to CFLAGS xtensa: build kernel with text-section-literals xtensa: use call instead of callx in assembly code xtensa: clean up fixups in assembly code xtensa: clean up word alignment macros in assembly code xtensa: clean up functions in assembly code xtensa: consolidate kernel stack size related definitions xtensa: print hardware config ID on startup xtensa: enable stack protector xtensa: clean up custom-controlled debug output xtensa: clean up exception handling structure xtensa: implement early_trap_init xtensa: extract init_kio xtensa: don't clear swapper_pg_dir in paging_init xtensa: move fixmap and kmap just above the KSEG xtensa: add support for KASAN xtensa: use __memset in __xtensa_clear_user xtensa: use generic strncpy_from_user with KASAN xtensa: print kernel sections info in mem_init xtensa: fix futex_atomic_cmpxchg_inatomic .../features/debug/KASAN/arch-support.txt | 2 +- .../features/debug/stackprotector/arch-support.txt | 2 +- Documentation/xtensa/mmu.txt | 78 ++++++------ arch/xtensa/Kconfig | 7 ++ arch/xtensa/Makefile | 7 +- arch/xtensa/boot/boot-redboot/bootstrap.S | 1 + arch/xtensa/boot/lib/Makefile | 6 + arch/xtensa/include/asm/asmmacro.h | 40 ++++++ arch/xtensa/include/asm/current.h | 4 +- arch/xtensa/include/asm/fixmap.h | 4 +- arch/xtensa/include/asm/futex.h | 23 ++-- arch/xtensa/include/asm/highmem.h | 2 +- arch/xtensa/include/asm/kasan.h | 37 ++++++ arch/xtensa/include/asm/kmem_layout.h | 7 ++ arch/xtensa/include/asm/linkage.h | 9 ++ arch/xtensa/include/asm/mmu_context.h | 1 + arch/xtensa/include/asm/nommu_context.h | 4 + arch/xtensa/include/asm/page.h | 2 - arch/xtensa/include/asm/pgtable.h | 3 +- arch/xtensa/include/asm/ptrace.h | 15 +-- arch/xtensa/include/asm/regs.h | 1 + arch/xtensa/include/asm/stackprotector.h | 40 ++++++ arch/xtensa/include/asm/string.h | 23 +++- arch/xtensa/include/asm/thread_info.h | 13 +- arch/xtensa/include/asm/traps.h | 35 ++++++ arch/xtensa/include/asm/uaccess.h | 9 +- arch/xtensa/kernel/Makefile | 3 - arch/xtensa/kernel/align.S | 7 +- arch/xtensa/kernel/asm-offsets.c | 16 +++ arch/xtensa/kernel/coprocessor.S | 3 +- arch/xtensa/kernel/entry.S | 103 ++++++--------- arch/xtensa/kernel/head.S | 10 +- arch/xtensa/kernel/module.c | 19 ++- arch/xtensa/kernel/pci.c | 30 ++--- arch/xtensa/kernel/process.c | 6 + arch/xtensa/kernel/setup.c | 49 +++++--- arch/xtensa/kernel/signal.c | 8 +- arch/xtensa/kernel/traps.c | 64 +++++----- arch/xtensa/kernel/vectors.S | 17 ++- arch/xtensa/kernel/vmlinux.lds.S | 90 ++++---------- arch/xtensa/kernel/xtensa_ksyms.c | 5 + arch/xtensa/lib/checksum.S | 74 +++++------ arch/xtensa/lib/memcopy.S | 81 +++++------- arch/xtensa/lib/memset.S | 45 +++---- arch/xtensa/lib/pci-auto.c | 45 ++----- arch/xtensa/lib/strncpy_user.S | 60 ++++----- arch/xtensa/lib/strnlen_user.S | 28 ++--- arch/xtensa/lib/usercopy.S | 138 +++++++++------------ arch/xtensa/mm/Makefile | 5 + arch/xtensa/mm/cache.c | 3 - arch/xtensa/mm/fault.c | 22 ++-- arch/xtensa/mm/init.c | 36 ++++-- arch/xtensa/mm/kasan_init.c | 95 ++++++++++++++ arch/xtensa/mm/mmu.c | 31 ++--- arch/xtensa/mm/tlb.c | 6 +- arch/xtensa/platforms/iss/console.c | 4 +- arch/xtensa/platforms/iss/network.c | 14 +-- 57 files changed, 829 insertions(+), 663 deletions(-) create mode 100644 arch/xtensa/include/asm/kasan.h create mode 100644 arch/xtensa/include/asm/linkage.h create mode 100644 arch/xtensa/include/asm/stackprotector.h create mode 100644 arch/xtensa/mm/kasan_init.c -- Thanks. -- Max
