The child of a video bus device is not alway a video device.

6847aa5cce rt2x00: LEDS build failure
Config symbols that select LEDS_CLASS need to depend on NEW_LEDS so that
undefined symbols are not used in the build.

The alternative is to select NEW_LEDS, which some drivers do.

c6d8f400cc rtc: Ramtron FM3130 RTC support
Ramtron FM3130 is a chip with two separate devices inside, RTC clock and
FRAM.  This driver provides only RTC functionality.

This chip is met in lots of custom boards with AT91SAMXXXX CPU I work
with, is cheap and in no way better or worse than any other RTC on market.
 While it is mostly met on much smaller devices, I think it is great to
have it supported in Linux.

e6d2bb2bac rtc: make HPET_RTC_IRQ track HPET_EMULATE_RTC
More Kconfig tweaks related to the legacy PC RTC code:

 - Describe the legacy PC RTC driver as such ... it's never quite
   been clear that this driver is for PC RTCs, and now it's fair
   to call this the "legacy" driver.

 - Force it to understand about HPET stealing its IRQs ... kernel
   code does this always when HPET is in use, there should be no
   option for users to goof up the config.

This seems to fix kernel bugzilla #10729.

1da2e3d679 provide rtc_cmos platform device
Recently (around 2.6.25) I've noticed that RTC no longer works for me.  It
turned out this is because I use pnpacpi=off kernel option to work around
the parport_pc bugs.  I always did so, but RTC used to work fine in the
past, and now it have regressed.

The patch fixes the problem by creating the platform device for the RTC
when PNP is disabled.  This may also help running the PNP-enabled kernel
on an older PCs.

643b52b9c0 radix-tree: fix small lockless radix-tree bug
We shrink a radix tree when its root node has only one child, in the left
most slot.  The child becomes the new root node.  To perform this
operation in a manner compatible with concurrent lockless lookups, we
atomically switch the root pointer from the parent to its child.

However a concurrent lockless lookup may now have loaded a pointer to the
parent (and is presently deciding what to do next).  For this reason, we
also have to keep the parent node in a valid state after shrinking the
tree, until the next RCU grace period -- otherwise this lookup with the
parent pointer may not do the right thing.  Notably, we need to keep the
child in the left most slot there in case that is requested by the lookup.

This is all pretty standard RCU stuff.  It is worth repeating because in
my eagerness to obey the radix tree node constructor scheme, I had broken
it by zeroing the radix tree node before the grace period.

What could happen is that a lookup can load the parent pointer, then
decide it wants to follow the left most child slot, only to find the slot
contained NULL due to the concurrent shrinker having zeroed the parent
node before waiting for a grace period.  The lookup would return a false
negative as a result.

Fix it by doing that clearing in the RCU callback.  I would normally want
to rip out the constructor entirely, but radix tree nodes are one of those
places where they make sense (only few cachelines will be touched soon
after allocation).

This was never actually found in any lockless pagecache testing or by the
test harness, but by seeing the odd problem with my scalable vmap rewrite.
 I have not tickled the test harness into reproducing it yet, but I'll
keep working at it.

Fortunately, it is not a problem anywhere lockless pagecache is used in
mainline kernels (pagecache probe is not a guarantee, and brd does not
have concurrent lookups and deletes).

6c826818ff /proc/sysvipc/shm: fix 32-bit truncation of segment sizes
sysvipc_shm_proc_show() picks between format strings (based on the
expected maximum length of a SHM segment) in a way that prevents gcc from
performing format checks on the seq_printf() parameters.  This hid two
format errors - shp->shm_segsz and shp->shm_nattach are both unsigned
long, but were being printed as unsigned int and signed int respectively.
This leads to 32-bit truncation of SHM segment sizes reported in
/proc/sysvipc/shm.  (And for nattach, but that's less of a problem for
most users).

This patch makes the format string directly visible to gcc's format
specifier checker, and fixes the two broken format specifiers.

The generic nvram driver announces itself as
	'Macintosh non-volatile memory driver'
instead of 'Generic non-volatile memory driver'.  Fix that.

e59b6a5ab5 drivers/video/cirrusfb: fix RAM address printk
In the cirrusfb driver, the RAM address printk has a superfluous 'x' that
could be interpreted as "don't care", while it is actually a typo.  Fix
that.

c97aee9ba4 intel_rng: make device not found a warning
Since many distros load this driver by default (throw it against the wall
and see what sticks method).  Change the error message severity level to
avoid alarming users.  Isn't it annoying when users actually read the
error logs...

cef33400d0 mmc: wbsd: initialize tasklets before requesting interrupt
With CONFIG_DEBUG_SHIRQ set we will get an interrupt as soon as we
allocate one.  Tasklets may be scheduled in the interrupt handler but they
will be initialized after the handler returns, causing a BUG() in
kernel/softirq.c when they run.

Should fix this Fedora bug report:

f1ef9167ca uml: work around broken host PTRACE_SYSEMU
Fedora broke PTRACE_SYSEMU again, and UML crashes as a result when it
doesn't need to.  This patch makes the PTRACE_SYSEMU check fail gracefully
and makes UML fall back to PTRACE_SYSCALL.

that.

8cdbc2b982 capabilities: add (back) dummy support for KEEPCAPS
The dummy module is used by folk that run security conscious code(!?).  A
feature of such code (for example, dhclient) is that it tries to operate
with minimum privilege (dropping unneeded capabilities).  While the dummy
module doesn't restrict code execution based on capability state, the user
code expects the kernel to appear to support it.  This patch adds back
faked support for the PR_SET_KEEPCAPS etc., calls - making the kernel
behave as before 2.6.26.

For details see: http://bugzilla.kernel.org/show_bug.cgi?id=10748
