[Linux-stable-mirror] [PATCH v2 0/4] fix device-dax pud crash and fixup {pte, pmd, pud}_write

by Dan Williams

Changes since v1 [1]: * fix arm64 compilation, add __HAVE_ARCH_PUD_WRITE * fix sparc64 compilation, add __HAVE_ARCH_PUD_WRITE * fix s390 compilation, add a pud_write() helper --- Andrew, Here is a third version to the pud_write() fix [2], and some follow-on patches to use the '_access_permitted' helpers in fault and get_user_pages() paths where we are checking if the thread has access to write. I explicitly omit conversions for places where the kernel is checking the _PAGE_RW flag for kernel purposes, not for userspace access. Beyond fixing the crash, this series also fixes get_user_pages() and fault paths to honor protection keys in the same manner as get_user_pages_fast(). Only the crash fix is tagged for -stable as the protection key check is done just for consistency reasons since userspace can change protection keys at will. [1]: https://lists.01.org/pipermail/linux-nvdimm/2017-November/013249.html [2]: https://lists.01.org/pipermail/linux-nvdimm/2017-November/013237.html --- Dan Williams (4): mm: fix device-dax pud write-faults triggered by get_user_pages() mm: replace pud_write with pud_access_permitted in fault + gup paths mm: replace pmd_write with pmd_access_permitted in fault + gup paths mm: replace pte_write with pte_access_permitted in fault + gup paths arch/arm64/include/asm/pgtable.h | 1 + arch/s390/include/asm/pgtable.h | 6 ++++++ arch/sparc/include/asm/pgtable_64.h | 1 + arch/sparc/mm/gup.c | 4 ++-- arch/x86/include/asm/pgtable.h | 6 ++++++ fs/dax.c | 3 ++- include/asm-generic/pgtable.h | 9 +++++++++ include/linux/hugetlb.h | 8 -------- mm/gup.c | 2 +- mm/hmm.c | 8 ++++---- mm/huge_memory.c | 6 +++--- mm/memory.c | 8 ++++---- 12 files changed, 39 insertions(+), 23 deletions(-)

[Linux-stable-mirror] [PATCH] MIPS: Fix odd fp register warnings with MIPS64r2

by James Hogan

From: James Hogan <jhogan(a)kernel.org> Building 32-bit MIPS64r2 kernels produces warnings like the following on certain toolchains (such as GNU assembler 2.24.90, but not GNU assembler 2.28.51) since commit 22b8ba765a72 ("MIPS: Fix MIPS64 FP save/restore on 32-bit kernels"), due to the exposure of fpu_save_16odd from fpu_save_double and fpu_restore_16odd from fpu_restore_double: arch/mips/kernel/r4k_fpu.S:47: Warning: float register should be even, was 1 ... arch/mips/kernel/r4k_fpu.S:59: Warning: float register should be even, was 1 ... This appears to be because .set mips64r2 does not change the FPU ABI to 64-bit when -march=mips64r2 (or e.g. -march=xlp) is provided on the command line on that toolchain, from the default FPU ABI of 32-bit due to the -mabi=32. This makes access to the odd FPU registers invalid. Fix by explicitly changing the FPU ABI with .set fp=64 directives in fpu_save_16odd and fpu_restore_16odd, and moving the undefine of fp up in asmmacro.h so fp doesn't turn into $30.
