Installing SAs using the XFRM_STATE_AF_UNSPEC fails on hosts with
support for one address family only. This patch accepts such SAs, even
if the processing of not supported packets will fail.

After flush the SPD entries, dump the SPD entries will cause kernel painc.
Used the following commands to reproduct:
- echo 'spdflush;' | setkey -c
- echo 'spdadd 3ffe:501:ffff:ff01::/64 3ffe:501:ffff:ff04::/64 any -P out ipsec \
ah/tunnel/3ffe:501:ffff:ff00:200:ff:fe00:b0b0-3ffe:501:ffff:ff02:200:ff:fe00:a1a1/require;\
spddump;' | setkey -c
- echo 'spdflush; spddump;' | setkey -c
- echo 'spdadd 3ffe:501:ffff:ff01::/64 3ffe:501:ffff:ff04::/64 any -P out ipsec \
ah/tunnel/3ffe:501:ffff:ff00:200:ff:fe00:b0b0-3ffe:501:ffff:ff02:200:ff:fe00:a1a1/require;\
spddump;' | setkey -c
This is because when flush the SPD entries, the SPD entry is not remove
from the list.
This patch fix the problem by remove the SPD entry from the list.

It turns out that the following sequence of actions will reproduce the
oops:
1. Create a new RFCOMM device (using RFCOMMCREATEDEV ioctl)
2. (Try to) open the device
3. Release the RFCOMM device (using RFCOMMRELEASEDEV ioctl)
At this point, the "/dev/rfcomm*" device is still in use, but it is gone
from the internal list, so the device id can be reused.
4. Create a new RFCOMM device with the same device id as before
And now kobject will complain that the TTY already exists.
(See http://lkml.org/lkml/2008/7/13/89 for a reproducible test-case.)
This patch attempts to correct this by only removing the device from the
internal list of devices at the final unregister stage, so that the id
won't get reused until the device has been completely destructed.
This should be safe as the RFCOMM_TTY_RELEASED bit will be set for the
device and prevent the device from being reopened after it has been
released.

Newer GCC versions are a little bit picky about how to deal with format
arguments:
net/bluetooth/hci_sysfs.c: In function ‘hci_register_sysfs’:
net/bluetooth/hci_sysfs.c:418: warning: format not a string literal and no format arguments
It is simple enough to fix and makes the compiler happy.

With the introduction of CONFIG_DYNAMIC_PRINTK_DEBUG it is possible to
allow debugging without having to recompile the kernel. This patch turns
all BT_DBG() calls into pr_debug() to support dynamic debug messages.
As a side effect all CONFIG_BT_*_DEBUG statements are now removed and
some broken debug entries have been fixed.

The Bluetooth subsystem was not using the HCI Reset command when doing
device initialization. The Bluetooth 1.0b specification was ambiguous
on how the device firmware was suppose to handle it. Almost every device
was triggering a transport reset at the same time. In case of USB this
ended up in disconnects from the bus.
All modern Bluetooth dongles handle this perfectly fine and a lot of
them actually require that HCI Reset is sent. If not then they are
either stuck in their HID Proxy mode or their internal structures for
inquiry and paging are not correctly setup.
To handle old and new devices smoothly the Bluetooth subsystem contains
a quirk to force the HCI Reset on initialization. However maintaining
such a quirk becomes more and more complicated. This patch turns the
logic around and lets the old devices disable the HCI Reset command.
The only device where the HCI_QUIRK_NO_RESET is still needed are the
original Digianswer devices and dongles with an early CSR firmware.
CSR reported that they fixed this for version 12 firmware. The last
official release of version 11 firmware is build ID 115. The first
version 12 candidate was build ID 117.

After adding proper lockdep annotations for Bluetooth protocols the case
when lockdep is disabled produced two compiler warnings:
net/bluetooth/af_bluetooth.c:60: warning: ‘bt_key_strings’ defined but not used
net/bluetooth/af_bluetooth.c:71: warning: ‘bt_slock_key_strings’ defined but not used

them and re-arranging the code a little bit.

};
sizeof(struct hci_dev_list_req) == 4, so the two bytes immediately
following "dev_num" will never be initialized. When this structure
is copied to userspace, these uninitialized bytes are leaked.
Fix by using kzalloc() instead of kmalloc(). Found using kmemcheck.

When the "hpwdt" module is loaded (even if the /dev/watchdog device is not
opened), then kdump does not work. The panic kernel either does not start at
all or crash in various places.
The problem is that hpwdt_pretimeout is registered with register_die_notifier()
with the highest possible priority. Because it returns NOTIFY_STOP, the
crash_nmi_callback which is also registered with register_die_notifier()
is never executed. This causes the shutdown of other CPUs to fail.
Reverting the order is no option: The crash_nmi_callback executes HLT
and so never returns normally. Because of that, it must be executed as
last notifier, which currently is done.
So, that patch returns NOTIFY_OK to keep the crash_nmi_callback executed.

The address provided by the SMBIOS/DMI CRU information is mapped via
ioremap() in the virtual address space. However, since the address is
executed (i.e. call'd), we need to set that pages as executable.

To avoid memory allocation failure during bulk-read, pre-allocate
a bulk-read buffer, so that if there is only one bulk-reader at
a time, it would just use the pre-allocated buffer and would not
do any memory allocation. However, if there are more than 1 bulk-
reader, then only one reader would use the pre-allocated buffer,
while the other reader would allocate the buffer for itself.

Bulk-read allocates 128KiB or more using kmalloc. The allocation
starts failing often when the memory gets fragmented. UBIFS still
works fine in this case, because it falls-back to standard
(non-optimized) read method, though. This patch teaches bulk-read
to allocate exactly the amount of memory it needs, instead of
allocating 128KiB every time.
This patch is also a preparation to the further fix where we'll
have a pre-allocated bulk-read buffer as well. For example, now
the @bu object is prepared in 'ubifs_bulk_read()', so we could
path either pre-allocated or allocated information to
'ubifs_do_bulk_read()' later. Or teaching 'ubifs_do_bulk_read()'
not to allocate 'bu->buf' if it is already there.

Bulk-read allocates a lot of memory with 'kmalloc()', and when it
is/gets fragmented 'kmalloc()' fails with a scarry warning. But
because bulk-read is just an optimization, UBIFS keeps working fine.
Supress the warning by passing __GFP_NOWARN option to 'kmalloc()'.
This patch also introduces a macro for the magic 128KiB constant.
This is just neater.
Note, this is not really fixes the problem we had, but just hides
the warnings. The further patches fix the problem.

The LPT may have gaps in it because initially empty LEBs
are not added by mkfs.ubifs - because it does not know how
many there are. Then UBIFS allocates empty LEBs in the
reverse order that they are discovered i.e. they are
added to, and removed from, the front of a list. That
creates a gap in the middle of the LPT.
The function dirtying the LPT tree (for the purpose of
small model garbage collection) assumed that a gap could
only occur at the very end of the LPT and stopped dirtying
prematurely, which in turn resulted in the LPT running
out of space - something that is designed to be impossible.

We print 'ino_t' type using '%lu' printk() placeholder, but this
results in many warnings when compiling for Alpha platform. Fix
this by adding (unsingned long) casts.

Remove the "UBIFS background thread ubifs_bgd0_0 started" message.
We kill the background thread when we switch to R/O mode, and
start it again whan we switch to R/W mode. OLPC is doing this
many times during boot, and we see this message many times as
well, which is irritating. So just kill the message.

It is possible for a shadow page to have a parent link
pointing to a freed page. When zapping a high level table,
kvm_mmu_page_unlink_children fails to remove the parent_pte link.
For that to happen, the child must be unreachable via the shadow
tree, which can happen in shadow_walk_entry if the guest pte was
modified in between walk() and fetch(). Remove the parent pte
reference in such case.
Possible cause for oops in bug #2217430.

When the VM exits, we must call put_page() for every page referenced in the
shadow TLB.
Without this patch, we usually leak 30-50 host pages (120 - 200 KiB with 4 KiB
pages). The maximum number of pages leaked is the size of our shadow TLB, 64
pages.

If an interrupt cannot be injected for some reason (say, page fault
when fetching the IDT descriptor), the interrupt is marked for
reinjection. However, if an NMI is queued at this time, the NMI
will be injected instead and the NMI will be lost.
Fix by deferring the NMI injection until the interrupt has been
injected successfully.
