+Subject: [PATCH] x86: work around legacy_max_proc being 0 while HTT feature
+ bit is set
+
+The Intel manual says that legacy_max_proc (CPUID.1.EBX[16-23]) is valid
+if CPUID.1.EDX.HTT[bit 28] is set.
+AMD (at least recent ones) don't say anything about it being invalid.
+
+Unfortunately some Qemu config may keep the former at 0 with the latter set.
+At least this happens when libvirt passes -cpu EPYC-Rome,ht=on to Qemu
+(which sets the HTT bit), and -smp 32,maxcpus=48,sockets=48,cores=1,threads=1
+says each CPU is single threaded (which keeps legacy_max_log_proc to 0).
+This config comes from https://bugzilla.opensuse.org/show_bug.cgi?id=1236038
+
+Calling flsl on this invalid mask leads to undefined behavior and some division
+by zero later (depending on the compiler).
+
+Check whether legacy_max_proc is 0 before using it.
+If 0, assume legacy_max_log_proc is 1, just like we did when HTT is unset.
+
+Thanks to Georg Pfuetzenreuter for the report
+and Anthony Iliopoulos for the debugging.

+- update to 2.11.2 (jsc#PED-11875)
+  * Add missing CPU info attrs on aarch64 on Linux.
+  * Use ACPI CPPC on Linux to get better information about cpukinds,
+    at least on AMD CPUs.
+  * Fix crash when manipulating cpukinds after topology
+    duplication.
+  * Fix missing input target checks in memattr functions
+  * Fix a memory leak when ignoring NUMA distances on FreeBSD.
+  * Fix build failure on old Linux distributions without accessat().
+  * Fix non-Windows importing of XML topologies and CPUID dumps exported
+    on Windows.
+  * hwloc-calc --cpuset-output-format systemd-dbus-api now allows.
+    to generate AllowedCPUs information for systemd slices.
+    See the hwloc-calc manpage for examples.
+  * Some fixes in manpage EXAMPLES and split them into subsections.
+  * Fix bash completions
+  * API
+    + Add HWLOC_MEMBIND_WEIGHTED_INTERLEAVE memory binding policy on
+      Linux 6.9+.
+      - weighted_interleave_membind is added to membind support bits.
+      - The "weighted" policy is added to the hwloc-bind tool.
+    + Add hwloc_obj_set_subtype().
+  * GPU support
+    + Don't hide the GPU NUMA node on NVIDIA Grace Hopper.
+    + Get Intel GPU OpenCL device locality.
+    + Add bandwidths between subdevices in the LevelZero XeLinkBandwidth
+      matrix.
+    + Fix PCI Gen4+ link speed of NVIDIA GPU obtained from NVML.
+  * Tools
+    + Option --best-memattr may now return multiple nodes. Additional
+      configuration flags may be given to tweak its behavior.
+    + hwloc-info has a new --get-attr option to get a single attribute.
+    + hwloc-info now supports "levels", "support" and "topology"
+      special keywords for backward compatibility for hwloc 3.0.
+    + The --taskset command-line option is superseded by the new
+      --cpuset-output-format which also allows to export as list.
+    + hwloc-calc may now import bitmasks described as a list of bits
+      with the new "--cpuset-input-format list".
+  * Misc
+    + The MemoryTiersNr info attribute in the root object now says how many
+      memory tiers were built.
+    + Fix the management of infinite cpusets in the bitmap printf/sscanf
+      API as well as in command-line tools.
+    + Add section "Compiling software on top of hwloc's C API" in the
+      documentation with examples for GNU Make and CMake.
