This is on v6.4-rc1. I fat-fingered the make target (I intended
"pciehp.o", not "pciehp.c"), then interrupted the build when I noticed
my mistake:
06:04:15 ~/linux (hotplug)$ make drivers/pci/hotplug/pciehp.c
SYNC include/config/auto.conf.cmd
^Cmake: *** [include/config/auto.conf.cmd] Deleting file 'include/generated/rustc_cfg'
make: *** [include/config/auto.conf.cmd] Deleting file 'include/generated/autoconf.h'
make[2]: *** [scripts/kconfig/Makefile:77: syncconfig] Interrupt
make[1]: *** [Makefile:692: syncconfig] Interrupt
make: *** [Makefile:793: include/config/auto.conf.cmd] Interrupt
Subsequent builds now fail ("pciehp.o" is *also* an incorrect target,
but doesn't seem related to the error):
06:04:22 ~/linux (hotplug)$ make drivers/pci/hotplug/pciehp.o

I finally got the right target, but the build still fails:
06:04:39 ~/linux (hotplug)$ make drivers/pci/hotplug/
CALL scripts/checksyscalls.sh
DESCEND objtool

After "make distclean", everything works as expected, so maybe this is
just the expected behavior after my initial user error? I dunno; it
seemed surprising. Just FYI.
