[Stable-8.0.5 15/43] Fixed incorrect LLONG alignment for openrisc and cr


From: Michael Tokarev
Subject: [Stable-8.0.5 15/43] Fixed incorrect LLONG alignment for openrisc and cris
Date: Sat, 9 Sep 2023 15:59:41 +0300

From: Luca Bonissi <qemu@bonslack.org>

OpenRISC (or1k) has long long alignment to 4 bytes, but currently not
defined in abitypes.h. This lead to incorrect packing of /epoll_event/
structure and eventually infinite loop while waiting for file
descriptor[s] event[s].

Fixed also CRIS alignments (1 byte for all types).
