6460b4cceb [PATCH] ppc32: improve timebase sync for SMP
Currently the procedure in the ppc32 kernel that synchronizes the timebase
registers across an SMP powermac system does so by setting both timebases
to zero.  That is OK at boot but causes problems if done later.  So that we
can do hotplug CPU on these machines, this patch changes the code so it
reads the timebase from one CPU and transfers the value to the other CPU. 
(Hotplug CPU is needed for sleep (aka suspend to RAM) to work.)

35b535d9cc [PATCH] ppc32: ppc4xx_pic - add acknowledge when enabling level-sensitive IRQ
This patch adds interrupt acknowledge to the PPC4xx PIC enable_irq
implementation for level-sensitive IRQ sources.  This helps in cases when
enable/disable_irq is used in interrupt handlers for hardware, which
requires IRQ acknowledge to be issued from non-interrupt context (e.g. 
when actual ACK in device needs an I2C transaction).  For such strange
hardware, interrupt handler disables IRQ and defers actual ACK to some
other context.  When this happens, IRQ is enabled again.  For
level-sensitive sources we get spurious triggering right after IRQ is
enabled.  This patch fixes this.

Suggested by Tolunay Orkun <listmember@orkun.us>.

16acbc624e [PATCH] ppc32: fix bogosity in process-freezing code
The code that went into arch/ppc/kernel/signal.c recently to handle process
freezing seems to contain a dubious assumption: that a process that calls
do_signal when PF_FREEZE is set will have entered the kernel because of a
system call.  This patch removes that assumption.

0c9b79429c [PATCH] SELinux: add support for NETLINK_KOBJECT_UEVENT
This patch adds SELinux support for the KOBJECT_UEVENT Netlink family, so
that SELinux can apply finer grained controls to it.  For example, security
policy for hald can be locked down to the KOBJECT_UEVENT Netlink family
only.  Currently, this family simply defaults to the default Netlink socket
class.

Note that some new permission definitions are added to sync with changes in
the core userspace policy package, which auto-generates header files.

6775cab98b [PATCH] Fix dst_destroy() race
When we are not the real parent of the dst (e.g., when we're xfrm_dst and
the child is an rtentry), it may already be on the GC list.

In fact the current code is buggy to, we need to check dst->flags before
the dec as dst may no longer be valid afterwards.

4c4c402d6c [PATCH] meminfo: add Cached underflow check

The cause is that get_page_cache_size() is an approximate value, and for a

d345734267 [PATCH] filemap_getpage can block when MAP_NONBLOCK specified
We will return NULL from filemap_getpage when a page does not exist in the
page cache and MAP_NONBLOCK is specified, here:

	page = find_get_page(mapping, pgoff);
	if (!page) {
		if (nonblock)
			return NULL;
		goto no_cached_page;
	}

But we forget to do so when the page in the cache is not uptodate.  The
following could result in a blocking call:

	/*
	 * Ok, found a page in the page cache, now we need to check
	 * that it's up-to-date.
	 */
	if (!PageUptodate(page))
		goto page_not_uptodate;

This was unexported by Arjan because we have no current users.

However, during a conversion from tasklets to workqueues of the parisc led
functions, we ran across a case where this was needed.  In particular, the
open coded equivalent of cancel_rearming_delayed_workqueue was implemented
incorrectly, which is, I think, all the evidence necessary that this is a
useful API.

From: Russell King <rmk+lkml@arm.linux.org.uk>

ARM wasn't raising a SIGBUS with a siginfo structure.  Fix
__do_user_fault() to allow us to use it for SIGBUS conditions, and arrange
for the sigbus path to use this.

We need to prevent the siginfo code being called if we do not have a user
space context to call it, so consolidate the "user_mode()" tests.
