That # makes any advice hint to reach into the remote process. # # This patch removes the mm ownership check. With it, it will lose the # ability that local process could give any advice hint with vector # interface for some reason (e.g., performance). Since there is no # concrete example in upstream yet, it would be better to remove the # abiliity at this moment and need to review when such new advice comes # up. # # Fixes: ecb8ac8b1f14 ("mm/madvise: introduce process_madvise() syscall: an external memory hinting API") # Reported-by: Jann Horn <jannh@google.com> # Suggested-by: Jann Horn <jannh@google.com> # Signed-off-by: Minchan Kim <minchan@kernel.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-gcc --version # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-ld --version # < git log --format=%s --max-count=1 a68a0262abdaa251e12c53715f48e698a18ef402 # < make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MIPS_CPS_NS16550_BASE=0x1b0003f8 # Added to kconfig CONFIG_MIPS_CPS_NS16550_SHIFT=0 # Added to kconfig # < make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- help # make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- olddefconfig .config:12742:warning: override: reassigning to symbol MIPS_CPS_NS16550_SHIFT # make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- /kisskb/src/drivers/input/joystick/analog.c:160:2: warning: #warning Precise timer not defined for this architecture.
