When offlining a CPU fails in sched_cpu_deactivate() after the SMT present counter has been decremented, then the function aborts but fails to increment the SMT present counter and leaves it imbalanced. Consecutive operations cause it to underflow. Add the missing fixup for the error path. As SMT accounting the runqueue needs to marked online again in the error exit path to restore consistent state.

This went unnoticed in testing as some compilers hoist the access into the non-preemotible section where the pointer is actually used, but obviously compilers can rightfully invoke it where the code put it. Move it into the non-preemptible section right to the actual usage side to cure it. - The clocksource watchdog is supposed to emit a warning when the retry count is greater than one and the number of retries reaches the limit. The condition is backwards and warns always when the count is greater than one. Fixup the condition to prevent spamming dmesg. Thanks, tglx ------------------> Paul E.

A recent change in the ACPI code which consolidated code pathes moved the invocation of init_freq_invariance_cppc() to be moved to a CPU hotplug handler. The first invocation on AMD CPUs ends up enabling a static branch which dead locks because the static branch enable tries to acquire cpu_hotplug_lock but that lock is already held write by the hotplug machinery. Use static_branch_enable_cpuslocked() instead and take the hotplug lock read for the Intel code path which is invoked from the architecture code outside of the CPU hotplug operations. - Fix the number of reserved bits in the sev_config structure bit field so that the bitfield does not exceed 64 bit. - Add missing Zen5 model numbers - Fix the alignment assumptions of pti_clone_pgtable() and clone_entry_text() on 32-bit: The code assumes PMD aligned code sections, but on 32-bit the kernel entry text is not PMD aligned. So depending on the code size and location, which is configuration and compiler dependent, entry text can cross a PMD boundary. As the start is not PMD aligned adding PMD size to the start address is larger than the end address which results in partially mapped entry code for user space. That causes endless recursion on the first entry from userspace (usually #PF). Cure this by aligning the start address in the addition so it ends up at the next PMD start address. clone_entry_text() enforces PMD mapping, but on 32-bit the tail might eventually be PTE mapped, which causes a map fail because the PMD for the tail is not a large page mapping. Use PTI_LEVEL_KERNEL_IMAGE for the clone() invocation which resolves to PTE on 32-bit and PMD on 64-bit. - Zero the 8-byte case for get_user() on range check failure on 32-bit The recend consolidation of the 8-byte get_user() case broke the zeroing in the failure case again. Establish it by clearing ECX before the range check and not afterwards as that obvioulsy can't be reached when the range check fails =20 Thanks, tglx ------------------> Borislav Petkov (AMD) (1): x86/setup: Parse the builtin command line before merging David Gow (1): x86/uaccess: Zero the 8-byte get_range case on failure on 32-bit Jonathan Cameron (1): x86/aperfmperf: Fix deadlock on cpu_hotplug_lock Pavan Kumar Paluri (1): x86/sev: Fix __reserved field in sev_config Perry Yuan (1): x86/CPU/AMD: Add models 0x60-0x6f to the Zen5 range Peter Zijlstra (2): x86/mm: Fix pti_clone_pgtable() alignment assumption x86/mm: Fix pti_clone_entry_text() for i386 arch/x86/coco/sev/core.c | 2 +- arch/x86/include/asm/cmdline.h | 4 ++++ arch/x86/kernel/cpu/amd.c | 2 +- arch/x86/kernel/cpu/aperfmperf.c | 6 ++++-- arch/x86/kernel/setup.c | 2 +- arch/x86/lib/cmdline.c | 25 ++++++++++++++++++------- arch/x86/lib/getuser.S | 4 +++- arch/x86/mm/pti.c | 8 ++++---- 8 files changed, 36 insertions(+), 17 deletions(-) diff --git a/arch/x86/coco/sev/core.c b/arch/x86/coco/sev/core.c index 082d61d85dfc..de1df0cb45da 100644 --- a/arch/x86/coco/sev/core.c +++ b/arch/x86/coco/sev/core.c @@ -163,7 +163,7 @@ struct sev_config { */ use_cas : 1, =20 - __reserved : 62;
