| fix-test-several-levels-same-type | commit 9693e9f5f8ea3df749263faadc0eab77184dffb8 (HEAD -> master, mine/sscanf) hwloc_type_sscanf: fix test when host has several levels with same type E.g. with HWLOC_SYNTHETIC="group:2 group:2 pu:2" ./tests/hwloc/hwloc_type_sscanf The presence of the two group levels makes the check for level depth fail for the hwloc_obj_type_string case which does not expose attributes which allow to distinguish them.

| work_around_legacy_max_proc_being_0 | commit 452765963af7532add7060edfefb06dd05a4cb26 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.
