a bug search for "zpci" yielded no results, so I decided to file this as a new
bug.

Regarding the actual details: please see "steps to reproduce" below (to me it
*seems* the missing PCI devices are a secondary error due to the missing zpci
initialization, which in turn is due to the missing CPU facilities).

Please also note that I haven't tried any other kernel releases besides the
default kernel shipped with OpenSUSE Tumbleweed (which, at the time of this
writing is 5.15.3)

Interesting questions in this regard:
1. Are other CPU facilities missing, too (besides the two mentioned ones "69"
and "71")?
2. Is there something like a reference list of all CPU facilities that
"normally" are/should be supported?

TIA for any additional help/info.

Reproducible: Always

Steps to Reproduce:
1. lspci -v / lspci -k
=> no devices listed (but interestingly, the exit status of both commands is
zero)
2. sudo dmesg | grep zpci
=> zpci: PCI is not supported because CPU facilities 69 or 71 are not available
3. grep facilities /proc/cpuinfo
=> facilities      : 0 1 2 3 4 6 7 8 9 10 12 14 15 16 17 18 19 20 21 22 23 24
25 26 27 28 30 31 32 33 34 35 36 37 38 40 41 42 43 44 45 46 47 48 49 50 51 52
53 54 55 57 58 59 60 61 73 74 75 76 77 80 81 82 128 129 130 131 133 134 135 146
147 148 150 151 152 155 156 168
=> both CPU facilities indeed seem to be missing (note that the next facility
number after "61" is "73")
Actual Results:  
no PCI devices

Expected Results:  
The "lspci" command should list some PCI devices
