Pls pull, thx. --- The following changes since commit 6ee1d745b7c9fd573fba142a2efdad76a9f1cb04: Linux 5.11-rc5 (2021-01-24 16:47:14 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git tags/x86_urgent_for_v5.11_rc7 for you to fetch changes up to 816ef8d7a2c4182e19bc06ab65751cb9e3951e94: x86/efi: Remove EFI PGD build time checks (2021-02-06 13:54:14 +0100) ---------------------------------------------------------------- - Remove superfluous EFI PGD range checks which lead to those assertions failing with certain kernel configs and LLVM. - Disable setting breakpoints on facilities involved in #DB exception handling to avoid infinite loops. - Add extra serialization to non-serializing MSRs (IA32_TSC_DEADLINE and x2 APIC MSRs) to adhere to SDM's recommendation and avoid any theoretical issues. - Re-add the EPB MSR reading on turbostat so that it works on older kernels which don't have the corresponding EPB sysfs file. - Add Alder Lake to the list of CPUs which support split lock. - Fix %dr6 register handling in order to be able to set watchpoints with gdb again. - Disable CET instrumentation in the kernel so that gcc doesn't add ENDBR64 to kernel code and thus confuse tracing. ---------------------------------------------------------------- Borislav Petkov (2): tools/power/turbostat: Fallback to an MSR read for EPB x86/efi: Remove EFI PGD build time checks Dave Hansen (1): x86/apic: Add extra serialization for non-serializing MSRs Fenghua Yu (1): x86/split_lock: Enable the split lock feature on another Alder Lake CPU Josh Poimboeuf (1): x86/build: Disable CET instrumentation in the kernel Lai Jiangshan (2): x86/debug: Prevent data breakpoints on __per_cpu_offset x86/debug: Prevent data breakpoints on cpu_dr7 Peter Zijlstra (1): x86/debug: Fix DR6 handling Makefile | 6 ---- arch/x86/Makefile | 3 ++ arch/x86/include/asm/apic.h | 10 ------ arch/x86/include/asm/barrier.h | 18 +++++++++++ arch/x86/kernel/apic/apic.c | 4 +++ arch/x86/kernel/apic/x2apic_cluster.c | 6 ++-- arch/x86/kernel/apic/x2apic_phys.c | 9 ++++-- arch/x86/kernel/cpu/intel.c | 1 + arch/x86/kernel/hw_breakpoint.c | 61 +++++++++++++++++++++++------------ arch/x86/platform/efi/efi_64.c | 19 ----------- tools/power/x86/turbostat/turbostat.c | 10 +++++- 11 files changed, 85 insertions(+), 62 deletions(-) -- Regards/Gruss, Boris.
