Subject: Introduce compat_u64 and compat_s64 types
From: Arnd Bergmann <arnd@arndb.de>

One common problem with 32 bit system call and ioctl emulation is the
different alignment rules between i386 and 64 bit machines.  A number of
drivers work around this by marking the compat structures as
'attribute((packed))', which is not the right solution because it breaks
all the non-x86 architectures that want to use the same compat code.

Hopefully, this patch improves the situation, it introduces two new types,
compat_u64 and compat_s64.  These are defined on all architectures to have
the same size and alignment as the 32 bit version of u64 and s64.
