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
in linux-user 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):

Re-posting to add "signed-off-by" line. Removing also unused functions

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

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

Make the alarm code modular, removing #ifdef from the generic code and
abstract a common interface for all the timer. The result is functionally
equivalent to the old code.

The improvements - beyond the refactoring - are either specific to
Linux (HPET timer) or to UNIX in general (dynticks - POSIX timers are
used).
It may be possible to use one-shot timer on windows too, but I'm not
really familiar with win32 API.
