ext_int_info_t is no longer used in entry(64).S Instead do_extint is a C function that handles the hash search. As the structure is handled in C code, we can also remove the packed attribute to avoid alignment issues. (Currently there is no alignment problem in ext_int_info_t, even if packet) Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
