Merge tag 'asm-generic-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pull asm-generic updates from Arnd Bergmann:
"These are various cleanups, fixing a number of uapi header files to no
longer reference CONFIG_* symbols, and one patch that introduces the
new CONFIG_HAS_IOPORT symbol for architectures that provide working
inb()/outb() macros, as a preparation for adding driver dependencies
on those in the following release"
* tag 'asm-generic-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic:
Kconfig: introduce HAS_IOPORT option and select it as necessary
scripts: Update the CONFIG_* ignore list in headers_install.sh
pktcdvd: Remove CONFIG_CDROM_PKTCDVD_WCACHE from uapi header
Move bp_type_idx to include/linux/hw_breakpoint.h
Move ep_take_care_of_epollwakeup() to fs/eventpoll.c
Move COMPAT_ATM_ADDPARTY to net/atm/svc.c
