Commit 273024ded7b3 ("PCI: pcie, aer: flags to bits") made an effort
to reduce memory size of struct aer_err_info by converting flags and
small integers to bitfields.
So it seems the proper approach would be to take away 1 bit from
__pad1 or __pad2 and use that for the is_cxl flag.
I know bitfields are somewhat controversial, but it is what this
struct is using, so... :)
Thanks,
