It's that time of the year again.  Summer starts in the US, and people
want to sit at the beach with a new -rc candidate.

This reverts commit c8fdd247255a3a027cd9f66dcf93e6847d1d2f85.

It turns out the kernel was correct, and the gcc complaint was a gcc
bug.  The preferred stack boundary is expressed not in bytes, but in the
the log2() of the preferred boundary, so "-mpreferred-stack-boundary=2"
is in fact exactly what we want, but a gcc that is compiled for x86-64
will consider it an error (because the 64-bit calling sequence says that
the stack should be 16-byte aligned) even if we are then using "-m32" to
generate 32-bit code.

Most system calls seems to get added to i386 first. This patch
automatically generates a warning for any new system call which is
implemented on i386 but not the architecture currently being compiled.
On PowerPC at the moment, for example, it results in these warnings:
init/missing_syscalls.h:935:3: warning: #warning syscall sync_file_range not implemented
init/missing_syscalls.h:947:3: warning: #warning syscall getcpu not implemented
init/missing_syscalls.h:950:3: warning: #warning syscall epoll_pwait not implemented

The file scripts/checksyscalls.sh list a number of legacy system calls
that are ignored because they only makes sense on i386 systems.
