REGPARM has already gotten much testing, what about removing the
dependency on EXPERIMENTAL?
Additionally, this patch does:
- remove the useless "default n"
- remove note regarding binary only modules (nowadays, there are even
some binary only modules compiled with REGPARM=y available)

This patch address several issues in the current BSD Secure Levels code:
o plaintext_to_sha1: Missing check for a NULL return from __get_free_page
o passwd_write_file: A page is leaked if the password is wrong.
o fix securityfs registration order
o seclvl_init is a mess and can't properly tolerate failures, failure
path is upside down (deldif and delf should be switched)
Cleanups:
o plaintext_to_sha1: Use buffers passed in
o passwd_write_file: Use kmalloc() instead of get_zeroed_page()
o passwd_write_file: hashedPassword comparison is just memcmp
o s/ENOSYS/EINVAL/
o misc
(akpm: after some discussion it appears that the BSD secure levels feature
should be scheduled for removal. But for now, let's fix these problems up).

We have noticed lockups during boot when stress testing kexec on ppc64.
Two cpus would deadlock in scheduler code trying to grab already taken
spinlocks.
The double_rq_lock code uses the address of the runqueue to order the
taking of multiple locks. This address is a per cpu variable:
if (rq1 < rq2) {
spin_lock(&rq1->lock);
spin_lock(&rq2->lock);
} else {
spin_lock(&rq2->lock);
spin_lock(&rq1->lock);
}
On the other hand, the code in wake_sleeping_dependent uses the cpu id
order to grab locks:
for_each_cpu_mask(i, sibling_map)
spin_lock(&cpu_rq(i)->lock);
This means we rely on the address of per cpu data increasing as cpu ids
increase. While this will be true for the generic percpu implementation it
may not be true for arch specific implementations.
One way to solve this is to always take runqueues in cpu id order. To do
this we add a cpu variable to the runqueue and check it in the
double runqueue locking functions.

The current code follows the spec but uses an overlong delay. This would
be great if the hardware did. Several vendors however forget the D7
pulldown. Fortunately 0xFF isnt a sane reset state so we can use it to

over a long time)

The problem is in ip_push_pending_frames(), which uses:
if (!df) {
__ip_select_ident(iph, &rt->u.dst, 0);
} else {
iph->id = htons(inet->id++);
}
instead of ip_select_ident().
Right now I think the code is a nonsense. Most likely, I copied it from
old ip_build_xmit(), where it was really special, we had to decide
whether to generate unique ID when generating the first (well, the last)
fragment.
In ip_push_pending_frames() it does not make sense, it should use plain
ip_select_ident() instead.

The expectation mask has some particularities that requires a different
handling. The protocol number fields can be set to non-valid protocols,
ie. l3num is set to 0xFFFF. Since that protocol does not exist, the mask
tuple will not be dumped. Moreover, this results in a kernel panic when
nf_conntrack accesses the array of protocol handlers, that is PF_MAX (0x1F)
long.
This patch introduces the function ctnetlink_exp_dump_mask, that correctly
dumps the expectation mask. Such function uses the l3num value from the
expectation tuple that is a valid layer 3 protocol number. The value of the
l3num mask isn't dumped since it is meaningless from the userspace side.
