Just realized that "PCI device" and "Peripheral" are a bit confusing

what, there's a script to import linux kernel headers to QEMU.

From commit 412a8245 ("pci_regs.h: import from linux"):
```
It seems to make sense to import pci_regs.h from linux: why maintain our own?

As a first step, move the header to standard-headers, and add it to the update script.
```

I'm a little surprised and disappointed that the 2023 Linux Foundation TAB election only has five candidates running for the five open seats. All five of the candidates are existing TAB members.

It would seem like one of the issues the TAB should focus on this year is getting more people interested in TAB participation.

The last one (I think) is having only limited time budget to read.

Another big hurdle is just reading code without knowing what's behind.
