Subject: Bury the conditionals from kernel_thread/kernel_execve series
All architectures have
CONFIG_GENERIC_KERNEL_THREAD
CONFIG_GENERIC_KERNEL_EXECVE
__ARCH_WANT_SYS_EXECVE
None of them have __ARCH_WANT_KERNEL_EXECVE and there are only two callers
of kernel_execve() (which is a trivial wrapper for do_execve() now) left.
Kill the conditionals and make both callers use do_execve().

Subject: Wire up finit_module syscall
Linux was granted a new system call to load modules by file descriptor
in commit 34e1169d996a ("module: add syscall to load module from fd").
Wire it up for ia64 (ready for the Chrome port :-)

Subject: sanitize rt_sigaction() situation a bit
Switch from __ARCH_WANT_SYS_RT_SIGACTION to opposite
(!CONFIG_ODD_RT_SIGACTION); the only two architectures that
need it are alpha and sparc. The reason for use of CONFIG_...
instead of __ARCH_... is that it's needed only kernel-side
and doing it that way avoids a mess with include order on many
architectures.
