The CR2 corruption fixes which store CR2 early in the entry code # and hand the stored address to the fault handlers. # # - Revert a forgotten leftover of the dropped FSGSBASE series. # # - Plug a memory leak in the boot code. # # - Make the Hyper-V assist functionality robust by zeroing the shadow # page. # # - Remove a useless check for dead processes with LDT # # - Update paravirt and VMware maintainers entries. # # - A few cleanup patches addressing various compiler warnings" # # * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # x86/entry/64: Prevent clobbering of saved CR2 value # x86/hyper-v: Zero out the VP ASSIST PAGE on allocation # x86, boot: Remove multiple copy of static function sanitize_boot_params() # x86/boot/compressed/64: Remove unused variable # x86/boot/efi: Remove unused variables # x86/mm, tracing: Fix CR2 corruption # x86/entry/64: Update comments and sanity tests for create_gap # x86/entry/64: Simplify idtentry a little # x86/entry/32: Simplify common_exception # x86/paravirt: Make read_cr2() CALLEE_SAVE # MAINTAINERS: Update PARAVIRT_OPS_INTERFACE and VMWARE_HYPERVISOR_INTERFACE # x86/process: Delete useless check for dead process with LDT # x86: math-emu: Hide clang warnings for 16-bit overflow # x86/e820: Use proper booleans instead of 0/1 # x86/apic: Silence -Wtype-limits compiler warnings # x86/mm: Free sme_early_buffer after init # x86/boot: Fix memory leak in default_get_smp_config() # Revert "x86/ptrace: Prevent ptrace from clearing the FS/GS selector" and fix the test # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 c6dd78fcb8eefa15dd861889e0f59d301cb5230c # < make -s -j 48 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 allmodconfig WARNING: unmet direct dependencies detected for MTD_COMPLEX_MAPPINGS Depends on [n]: MTD [=m] && HAS_IOMEM [=n] Selected by [m]: -
