IDs are allocated when a previously unshared vfsmount becomes the
first member of a peer group.  When a new member is added to an
existing group, the ID is copied from one of the old members.

Setting the MNT_SHARED flag on members of a subtree is done as a
separate step, after all the IDs have been allocated.  This way an

i2c-algo-pca: Extend for future drivers

The separation between algorithm and adapter was unsharp at places. This was
partly hidden by the fact, that the ISA-driver allowed just one instance and
had all private data in static variables. This patch makes neccessary
preparations to add a platform driver on top of the algorithm, while still
supporting ISA. Note: Due to lack of hardware, the ISA-driver could not be
tested except that it builds.

Concerning the core struct i2c_algo_pca_data:

- A private data field was added, all hardware dependant data may go here.
  Similar to other algorithms, now a pointer to this data is passed to the
  adapter's functions. In order to make as less changes as possible to the
  ISA-driver, it leaves the private data empty and still only uses its static
  variables.

- A "reset_chip" function pointer was added; such a functionality must come
  from the adapter, not the algorithm.

- use a variable "i2c_clock" instead of a function pointer "get_clock",
  allowing for write access to a default in case a wrong value was supplied.

In the algorithm-file:

- move "i2c-pca-algo.h" into "linux/i2c-algo-pca.h"
- now using per_instance timeout values (i2c_adap->timeout)
- error messages specify the device, not only the driver name
- restructure initialization to easily support "i2c_add_numbered_adapter"
- drop "retries" and "own" (i2c address) as they were unused

(The state-machine for I2C-communication was not touched.)

- adapt to new algorithm

If pUStk is true, it means we are going to return user mode, hence we fetch
ar.itc to get time at leave from system.
It seems that it is not possible to interrupt the window if pUStk is true,
because interrupts are disabled early.  And also disabling interrupt makes
sense because it is safe for referring current_thread_info()->flags.

However interrupting the window while pUStk is true was possible.
The route was:
ia64_trace_syscall
-> .work_pending_syscall_end
-> .work_processed_syscall
Only in case entering the window from this route, interrupts are enabled
during in the window even if pUStk is true.  I suppose interrupts must be
disabled here anyway if pUStk is true.
I'm not sure but afraid that what kind of bad effect were there, other
than crazy system time which I found.

FYI, there was a commit 6f6d75825dc49b082906b84537b4df28293c2977 that
points out a bug at same point(exit of ia64_trace_syscall) in 2006.
It can be said that there was an another bug.

HID: fixup fullspeed interval on highspeed Afatech DVB-T IR kbd

endpoint descriptor for interrupt endpoints. This quirk fixes up that by
recalculating the right value for highspeed device.

At the time of hid configuration this quirk calculates which highspeed interval
value gives same interval delay as, or next smaller then, what it would be if
the original value would be interpreted as fullspeed value. In subsequent urbs
that new value is used instead.

Forming the 'hid->name' in usb_hid_config() was moved up to accommodate more
descriptive printk reporting the fixup.

In this patch the quirk is set for one such device: Afatech DVB-T 2 infrared
HID-keyboard. It reports value 16 which means 4,069s in highspeed while
obviously 16ms was intended. In this case quirk calculates new value to be 8
which gives when interpreted as highspeed value 16ms as wanted. The behavior of

[IPSEC]: Fix catch-22 with algorithm IDs above 31

As it stands it's impossible to use any authentication algorithms
with an ID above 31 portably.  It just happens to work on x86 but
fails miserably on ppc64.

The reason is that we're using a bit mask to check the algorithm
ID but the mask is only 32 bits wide.

After looking at how this is used in the field, I have concluded
that in the long term we should phase out state matching by IDs
because this is made superfluous by the reqid feature.  For current
applications, the best solution IMHO is to allow all algorithms when
the bit masks are all ~0.

The following patch does exactly that.

IB/ipath: Remove tests of PCI_MSI in ipath_iba7220.c

The PCI MSI interface is stubbed out properly so that all the
functions just return failure if PCI_MSI=n, so there's no reason to
have "#ifdef CONFIG_PCI_MSI" blocks in ipath_iba7220.c.

IB/ipath: Remove dependency on PCI_MSI || HT_IRQ

Before IBA7220 support was added, the ipath driver didn't support any
hardware unless PCI_MSI and/or HT_IRQ was enabled.  However, the
IBA7220 can generate INTx interrupts, so it makes sense to allow the
driver to be build even if PCI_MSI=n and HT_IRQ=n.

IB/ipath: Build IBA7220 code unconditionally

The new IBA7220 code added a call to ipath_init_iba7220_funcs() that
is compiled unconditionally, but only built the IBA7220 code if
PCI_MSI is enabled.  Fix this by building the IBA7220 file
unconditonally.

This fixes build breakage when PCI_MSI=n, HT_IRQ=y and
INFINIBAND_IPATH=y reported by Ingo Molnar <mingo@elte.hu>:

 drivers/built-in.o: In function `ipath_init_one':

IB/ipath: Remove reference to dev->class_dev

Commit 124b4dcb ("IB/ipath: add calls to new 7220 code and enable in
build") inadvertently added core to set dev->class_dev.dev back into
ib_ipath.  This is completely redundant since commit 1912ffbb ("IB: Set
class_dev->dev in core for nice device symlink"), which removed
class_dev setting from low-level drivers, and also will break the build
when class_dev is removed completely from struct ib_device.
