There is nothing special about having the init code separate from
the common code, so combine the two.
Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

The common oprofile code assumes the name "PMU" (from Intel's
performance management unit).  This is misleading when we
start adding oprofile support for other machine types which
don't use the same terminology.  Call it op_arm_* instead of
pmu_*.
Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

The oprofile suspend/resume was missing locking.  If we failed
to start oprofile on resume, we still reported that it was
enabled.  Instead, disable oprofile on error.

Make ARM independent of the way bootmem operates internally.  We
now map each node as we initialise it, and place the bootmem bitmap
inside each node, rather than all in the first node.

Including asm/hardware.h into asm/io.h can cause #define clashes

Andi Kleen reports that it seems to break things for some people,
and since it's purely a small optimization, revert it for now.

This bug is responsible for causing the infamous "Treason uncloaked"
messages that's been popping up everywhere since the printk was added.
It has usually been blamed on foreign operating systems.  However,
some of those reports implicate Linux as both systems are running
Linux or the TCP connection is going across the loopback interface.

In fact, there really is a bug in the Linux TCP header prediction code
that's been there since at least 2.1.8.  This bug was tracked down with
help from Dale Blount.

The effect of this bug ranges from harmless "Treason uncloaked"
messages to hung/aborted TCP connections.  The details of the bug
and fix is as follows.

When snd_wnd is updated, we only update pred_flags if
tcp_fast_path_check succeeds.  When it fails (for example,
when our rcvbuf is used up), we will leave pred_flags with
an out-of-date snd_wnd value.

When the out-of-date pred_flags happens to match the next incoming
packet we will again hit the fast path and use the current snd_wnd
which will be wrong.

In the case of the treason messages, it just happens that the snd_wnd
cached in pred_flags is zero while tp->snd_wnd is non-zero.  Therefore
when a zero-window packet comes in we incorrectly conclude that the
window is non-zero.

In fact if the peer continues to send us zero-window pure ACKs we
will continue making the same mistake.  It's only when the peer
transmits a zero-window packet with data attached that we get a
chance to snap out of it.  This is what triggers the treason
message at the next retransmit timeout.

This just makes sure that a thread's expiry times can't get reset after
it clears them in do_exit.

This is what allowed us to re-introduce the stricter BUG_ON() check in
a362f463.

This reverts commit 3de463c7.

Roland has another patch that allows us to leave the BUG_ON() in place
by just making sure that the condition it tests for really is always
true.

That goes in next.

There's a silly off-by-one error in the code that updates the expiration
of posix CPU timers, causing them to not be properly updated when they
hit exactly on their expiration time (which should be the normal case).

This causes them to then fire immediately again, and only _then_ get
properly updated.
