This # worked before but got broken recently when the LDT remap area was # moved. # # - Prevent a NULL pointer dereference in the resource control code # which can be triggered with certain mount options when the # requested resource is not available. # # - Enforce ordering of microcode loading vs. perf initialization on # secondary CPUs. Otherwise perf tries to access a non-existing MSR # as the boot CPU marked it as available. # # - Don't stop the resource control group walk early otherwise the # control bitmaps are not updated correctly and become inconsistent. # # - Unbreak kgdb by returning 0 on success from # kgdb_arch_set_breakpoint() instead of an error code. # # - Add more Icelake CPU model defines so depending changes can be # queued in other trees" # # * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # x86/microcode, cpuhotplug: Add a microcode loader CPU hotplug callback # x86/kasan: Fix boot with 5-level paging and KASAN # x86/fpu: Don't use current->mm to check for a kthread # x86/kgdb: Return 0 from kgdb_arch_set_breakpoint() # x86/resctrl: Prevent NULL pointer dereference when local MBM is disabled # x86/resctrl: Don't stop walking closids when a locksetup group is found # x86/fpu: Update kernel's FPU state before using for the fsave header # x86/mm/KASLR: Compute the size of the vmemmap section properly # x86/fpu: Use fault_in_pages_writeable() for pre-faulting # x86/CPU: Add more Icelake model numbers # mm/vmalloc: Avoid rare case of flushing TLB with weird arguments # mm/vmalloc: Fix calculation of direct map addr range # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 963172d9c7e862654d3d24cbcafb33f33ae697a8 # < make -s -j 80 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- allyesconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # yes \n | make -s -j 80 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- oldconfig yes: standard output: Broken pipe # make -s -j 80 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- /kisskb/src/drivers/hwtracing/intel_th/msu.c: In function 'msc_buffer_win_alloc': /kisskb/src/drivers/hwtracing/intel_th/msu.c:783:21: warning: unused variable 'i' [-Wunused-variable] int ret = -ENOMEM, i; ^ /kisskb/src/drivers/hwtracing/intel_th/msu.c: In function 'msc_buffer_win_free': /kisskb/src/drivers/hwtracing/intel_th/msu.c:863:6: warning: unused variable 'i' [-Wunused-variable] int i; ^ /kisskb/src/drivers/input/joystick/analog.c:160:2: warning: #warning Precise timer not defined for this architecture.
