Unfortunately, GCC 9.1 is expected to be be released without # support for MPX. This means that there was only a relatively small # window where folks could have ever used MPX. It failed to gain wide # adoption in the industry, and Linux was the only mainstream OS to ever # support it widely. # # Support for the feature may also disappear on future processors. # # This set completes the process that we started during the 5.4 merge # window when the MPX prctl()s were removed. XSAVE support is left in # place, which allows MPX-using KVM guests to continue to function" # # * tag 'mpx-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/daveh/x86-mpx: # x86/mpx: remove MPX from arch/x86 # mm: remove arch_bprm_mm_init() hook # x86/mpx: remove bounds exception code # x86/mpx: remove build infrastructure # x86/alternatives: add missing insn.h include # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 ccaaaf6fe5a5e1fffca5cca0f3fc4ec84d7ae752 # < make -s -j 24 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- allmodconfig # make -s -j 24 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 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;
