[PATCH] proc: Simplify the ownership rules for /proc

Currently in /proc if the task is dumpable all of files are owned by the tasks
effective users.  Otherwise the files are owned by root.  Unless it is the
/proc/<tgid>/ or /proc/<tgid>/task/<pid> directory in that case we always make
the directory owned by the effective user.

However the special case for directories is pointless except as a way to read
the effective user, because the permissions on both of those directories are
world readable, and executable.

/proc/<tgid>/status provides a much better way to read a processes effecitve
userid, so it is silly to try to provide that on the directory.

So this patch simplifies the code by removing a pointless special case and
gets us one step closer to being able to remove the hard coded /proc inode
numbers.

[PATCH] proc: Remove unnecessary and misleading assignments from proc_pid_make_inode

The removed fields are already set by proc_alloc_inode.  Initializing them in
proc_alloc_inode implies they need it for proper cleanup.  At least ei->pde

just remove the redundant assignments.

[PATCH] nfsd kconfig: select things at the closest tristate instead of bool

I noticed recently that my CONFIG_CRYPTO_MD5 turned into a y again instead
of m.  It turns out that CONFIG_NFSD_V4 is selecting it to be y even though
I've chosen to compile nfsd as a module.

In general when we have a bool sitting under a tristate it is better to
select things you need from the tristate rather than the bool since that
allows the things you select to be modules.

The following patch does it for nfsd.

The interresting part of it is the "virtual address 00200200", which is
LIST_POISON2.  I thought about some race condition, but as this is an UP
system, it leads to questions on how it can happen.  If we look at EFLAGS:
00010202, we see that interrupts are enabled at the time of the crash
(eflags & 0x200).

Finally, I don't understand all the capi code, but I think that
handle_minor_send() is racing somehow against capi_recv_message(), which
call both capiminor_del_ack().  So if an IRQ occurs in the middle of
capiminor_del_ack() and another instance of it is invoked, it leads to
linked list corruption.

I came up with the following patch.  With this, I could not reproduce the
crash anymore.  Clearly, this is not the correct fix for the issue.  As this
seems to be some locking issue, there might be more locking issues in that
code.  For example, doesn't the whole struct capiminor have to be locked
somehow?

[PATCH] Notify page fault call chain for x86_64

Currently in the do_page_fault() code path, we call notify_die(DIE_PAGE_FAULT,
...) to notify the page fault.  Since notify_die() is highly overloaded, this
page fault notification is currently being sent to all the components
registered with register_die_notification() which uses the same die_chain to
loop for all the registered components which is unnecessary.

In order to optimize the do_page_fault() code path, this critical page fault
notification is now moved to different call chain and the test results showed
great improvements.

And the kprobes which is interested in this notifications, now registers onto
this new call chain only when it need to, i.e Kprobes now registers for page
fault notification only when their are an active probes and unregisters from
this page fault notification when no probes are active.

I have incorporated all the feedback given by Ananth and Keith and everyone,
and thanks for all the review feedback.

[PATCH] Time: Use clocksource abstraction for NTP adjustments

Instead of incrementing xtime by tick_nsec + ntp adjustments, use the
clocksource abstraction to increment and scale time.  Using the clocksource
abstraction allows other clocksources to be used consistently in the face of
late or lost ticks, while preserving the existing behavior via the jiffies
clocksource.

This removes the need to keep time_phase adjustments as we just use the
current_tick_length() function as the NTP interface and accumulate time using
shifted nanoseconds.

The basics of this design was by Roman Zippel, however it is my own
interpretation and implementation, so the credit should go to him and the
blame to me.

[PATCH] keys: allocate key serial numbers randomly

Cause key_alloc_serial() to generate key serial numbers randomly rather than
in linear sequence.

Using an linear sequence permits a covert communication channel to be
established, in which one process can communicate with another by creating or
not creating new keys within a certain timeframe.  The second process can
probe for the expected next key serial number and judge its existence by the
error returned.

This is a problem as the serial number namespace is globally shared between
all tasks, regardless of their context.

[PATCH] Bluetooth: fix potential NULL ptr deref in dtl1_cs.c::dtl1_hci_send_frame()

There's a problem in drivers/bluetooth/dtl1_cs.c::dtl1_hci_send_frame()

If bt_skb_alloc() returns NULL, then skb_reserve(s, NSHL); will cause a
NULL pointer deref - ouch.  If we can't allocate the resources we require
we need to tell the caller by returning -ENOMEM.

Found by the coverity checker as bug #409

[PATCH] work around ppc64 bootup bug by making mutex-debugging save/restore irqs

It seems ppc64 wants to lock mutexes in early bootup code, with interrupts
disabled, and they expect interrupts to stay disabled, else they crash.
