Subject: [PATCH] Fixed incorrect LLONG alignment for openrisc and cris
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
r container and/or with cross-compiler):
- cris, m68k, microblaze, nios2, or1k, sh4, x86 (32bit)
See include/exec/user/abitypes.h to update the value.
OK, abitypes.h should be updated with the following patch (discard the
previous patch on syscall_defs.h):

and CASA.
Re-posting to add "signed-off-by" line. Removing also unused functions
from qemu-sparc (32bit) building, and consequently removed helper patch
(needed only by unused [removed] functions).

The or1k epoll_event structure - unlike other architectures - is packed,
so we need to define it as packed in qemu-user, otherwise it leads to
infinite loop due to missing file descriptor in the returned data:

final uint64_t parameters, leading to incorrect comparison on the RBTree
(only the first call to mmap on the upper 2GB memory will be successful).

On qemu-sparc (user-space), the CASA instruction is not handled for
SPARC32 even if the selected cpu (e.g. LEON3) supports it.
Following the patch that works. I created "fake" ld/st_asi helpers: it
seems all works fine, but I don't know if we should make real ld/st
helpers like for SPARC64 use

On 32bit qemu-user targets, memory allocation failed after about 2GB due
to incorrect signed (instead of the correct unsigned) "last" parameter
in pageflags_find and pageflags_next functions (file accel/tcg/user-exec.c).
The parameter, on 32bit targets, will be signed-extent to the 64bit

On qemu-sparc64 (userspace) the struct "target_stat64" is not correctly
padded, so the field st_rdev is not correctly aligned and will report
wrong major/minor (e.g. for /dev/zero it reports 0,0x1050 instead of
1,5).
