- We were statically predicting syscalls would be 32bit which meant every
  64bit syscall was guaranteed to be mispredicted. Just let the hardware
  predict this one.

- We shouldnt use blrl for indirect function calls, it is unlikely to be
  predicted correctly and corrupts the link prediction stack. We should
  use bctrl instead.

- Statically predict a branch in the system call path, favouring calls from
  userspace.

- Remove static prediction in pagefault path, hardware prediction should do
  a better job here.

It turns out in the non NUMA case, max_low_pfn doesnt get initialised
until init_bootmem so we need to move initialisation of max_pfn below
it.

I noticed excessive time in the pid hash functions on a ppc64 box. It
turns out the pid hash is being sized way too small, eg on a 16GB box:

PID hash table entries: 16 (order 4: 256 bytes)

The reason is that the pid hash init function uses max_pfn before it was
setup on ppc64. With the following patch things are good again:

PID hash table entries: 4096 (order 12: 65536 bytes)

As we discussed before, mutable headers should not be allowed after
the AH header.  In fact, this appears to be the intention of RFC 2402.
It is further clarified in section 3.1.1 of

http://www.ietf.org/internet-drafts/draft-ietf-ipsec-rfc2402bis-07.txt

This allows us to simplify the code in ah6.c.  As a result, this also
fixes the following issues:

* Dependence on skb->h in ah6_output().
* Bogus clearing of auth_data of 2nd AH header in ipv6_clear_mutable_options().

On some platforms, you'll want to support READ_IMPLIES_EXEC differently
depending on personality (e.g, native binary vs. x86 binary).

This supports that (and makes the code more readable while at it) by
replacing the old architecture-specific fixed LEGACY_BINARIES macro
define with a architecture-specific "elf_read_implies_exec_binary()"
helper function.

For now, x86 is the only user, and sets the "read implies exec" bit for
legacy apps.  ia64 and x86-64 are likely to want to do their own thing.

This makes it much easier on the callers, no need to
worry about races with vmtruncate() and friends, since
"install_page()" will just cleanly handle that case
and tell the caller about it.

Add is_highmem_idx() and is_normal_idx() to determine whether
a zone index is a highmem or normal zone.  Use this for
memmap_init_zone().

Don't bother zeroing the allocated memory inside alloc_buf() in the
n_tty line discipline.  alloc_buf() is static inline and is only
referenced by n_tty_open() which always clears the memory (once more).

No bug, just a minor cleanup

The recent changes to (6 Jul 04) pkt_cls.h are evil, you can't build a version
of 'tc' to work unless you know the kernel config!

It has several API problems:
  - API data structures change on kernel config options
  - new fields should be added at the end of a structure to allow
    binary compatibility.
 
This patch tries to clean this up.

This patch is a preparation for an update of the ECN encap/decap
code with respect to RFC3168.

It creates an enum of the four code-points defined by RFC3168
and uses them throughout the inet_ecn.h file.

The only non-trivial bit is in IP_ECN_set_ce/IP6_ECN_set_ce where
the patch uses INET_ECN_CE instead of 1.  This is OK as those
functions assume that the ECT bit is already set.

The stack allocation in crypt() is bogus as whether tmp_src/tmp_dst
is used is determined by factors unrelated to nbytes and
src->length/dst->length.

Since the condition for whether tmp_src/tmp_dst are used is very
complex, let's allocate them always instead of guessing.

This fixes a number of weird crashes including those AES crashes
that people have been seeing with the 2.4 backport + ipt_conntrack.
