The previous commit re-enabled hp_nid setup for IDT92HD73*, but
it's unneeded indeed for Dell laptops that have multiple headphones.
Setting the extra hp_nid results in a non-working "Headpohne" mixer
control. Thus hp_nid should be 0 for these dell models.
Also, the automatic addition of hp_nid should check whether it's
a dual-HP model or not. For dual-HPs, the pins are already checked
by the early workaround.

The ACPI interpreter usually runs with irqs enabled.
However, during suspend/resume it runs with
irqs disabled to evaluate _GTS/_BFS, as well as
by irqrouter_resume() which evaluates _CRS, _PRS, _SRS.

acpi_early_init() was changed to over-write the cmdline param,
making it really inconvenient to set debug flags at boot-time.
Also,
This sets the default level to "info", which is what all the ACPI
drivers use. So to enable messages from drivers, you only have to
supply the "layer" (a.k.a. "component"). For non-"info" ACPI core
and ACPI interpreter messages, you have to supply both level and
layer masks, as before.

Impact: fix wrong cache sharing detection on platforms supporting > 8 bit apicid's
In the presence of extended topology eumeration leaf 0xb provided
by cpuid, 32bit extended initial_apicid in cpuinfo_x86 struct will be
updated by detect_extended_topology(). At this instance, we should also
reinit the apicid (which could also potentially be extended to 32bit).
With out this there will potentially be duplicate apicid's populated in the
per cpu's cpuinfo_x86 struct, resulting in wrong cache sharing topology etc
detected by init_intel_cacheinfo().

Fix problem that deleting multiple logical drives could cause a panic.
It fixes a panic which can be easily reproduced in the following way: Just
create several "arrays," each with multiple logical drives via hpacucli,
then delete the first array, and it will blow up in deregister_disk(), in
the call to get_host() when it tries to dig the hba pointer out of a NULL
queue pointer.
The problem has been present since my code to make rebuild_lun_table
behave better went in.

On PAE systems, GEM allocates pages using shmem, and passes these
pages to be bound into AGP, however the AGP interfaces + the x86
set_memory interfaces all take unsigned long not dma_addr_t.
The initial fix for this was a mess, so we need to do this correctly
for 2.6.29.

When we read the write-intent-bitmap off the device, we currently
read a whole number of pages.
When PAGE_SIZE is 4K, this works due to the alignment we enforce
on the superblock and bitmap.
When PAGE_SIZE is 64K, this case read past the end-of-device
which causes an error.
When we write the superblock, we ensure to clip the last page
to just be the required size. Copy that code into the read path
to just read the required number of sectors.

The original ppp_generic code treated the netdev and struct ppp as
independent data structures which were freed separately. In moving the
ppp struct into the netdev, it is now possible for the private data to
be freed before the call to ppp_shutdown_interface(), which is bad.
The kfree(ppp) in ppp_destroy_interface() is also wrong; presumably
ppp hasn't worked since the above commit.
The following patch fixes both problems.

The kernel_accept() does not hold the module refcount of newsock->ops->owner,
so we need __module_get(newsock->ops->owner) code after call kernel_accept()
by hand.
In sunrpc, the module refcount is missing to hold. So this cause kernel panic.
Used following script to reproduct:
while [ 1 ];
do
mount -t nfs4 192.168.0.19:/ /mnt
touch /mnt/file
umount /mnt
lsmod | grep ipv6
done
This patch fixed the problem by add __module_get(newsock->ops->owner) to
kernel_accept(). So we do not need to used __module_get(newsock->ops->owner)
in every place when used kernel_accept().

Impact: enhancement
Ingo Molnar has asked about a way to remove items from the filter
lists. Currently, you can only add or replace items. The way
items are added to the list is through opening one of the list
files (set_ftrace_filter or set_ftrace_notrace) via append.
If the file is opened for truncate, the list is cleared.
echo spin_lock > /debug/tracing/set_ftrace_filter
The above will replace the list with only spin_lock
echo spin_lock >> /debug/tracing/set_ftrace_filter
The above will add spin_lock to the list.
Now this patch adds:
echo '!spin_lock' >> /debug/tracing/set_ftrace_filter
This will remove spin_lock from the list.
The limited glob features of these lists also can be notted.
echo '!spin_*' >> /debug/tracing/set_ftrace_filter
This will remove all functions that start with 'spin_'
Note:
echo '!spin_*' > /debug/tracing/set_ftrace_filter
will simply clear out the list (notice the '>' instead of '>>')

I happened to notice that the ibmphp hotplug driver does something
rather silly in its init routine. It purposely calls module_put so as
to underflow its module ref count to avoid being removed from the
kernel. This is bad practice, and wrong, since it provides a window for
subsequent module_gets to reset the refcount to zero, allowing an unload
to race in and cause all sorts of mysterious panics. If the module is
unsafe to load, simply omitting the module_exit parameter is sufficient
to prevent the kernel from allowing the unload.
