KOSAKI Motohiro 6837765963 mm: remove CONFIG_UNEVICTABLE_LRU config option
Currently, nobody wants to turn UNEVICTABLE_LRU off.  Thus this
configurability is unnecessary.

Magnus Damm 720b17e759 videobuf-dma-contig: zero copy USERPTR support
Since videobuf-dma-contig is designed to handle physically contiguous
memory, this patch modifies the videobuf-dma-contig code to only accept a
user space pointer to physically contiguous memory.  For now only
VM_PFNMAP vmas are supported, so forget hotplug.

On SuperH Mobile we use this with our sh_mobile_ceu_camera driver together
with various multimedia accelerator blocks that are exported to user space
using UIO.  The UIO kernel code exports physically contiguous memory to
user space and lets the user space application mmap() this memory and pass
a pointer using the USERPTR interface for V4L2 zero copy operation.

With this approach we support zero copy capture, hardware scaling and
various forms of hardware encoding and decoding.

Mel Gorman 6484eb3e2a page allocator: do not check NUMA node ID when the caller knows the node is valid
Callers of alloc_pages_node() can optionally specify -1 as a node to mean
"allocate from the current node".  However, a number of the callers in
fast paths know for a fact their node is valid.  To avoid a comparison and
branch, this patch adds alloc_pages_exact_node() that only checks the nid
with VM_BUG_ON().  Callers that know their node is valid are then
converted.

Yinghai Lu 3b0fde0fac firmware_map: fix hang with x86/32bit
Addresses http://bugzilla.kernel.org/show_bug.cgi?id=13484

Peer reported:
| The bug is introduced from kernel 2.6.27, if E820 table reserve the memory
| above 4G in 32bit OS(BIOS-e820: 00000000fff80000 - 0000000120000000
| (reserved)), system will report Int 6 error and hang up. The bug is caused by
| the following code in drivers/firmware/memmap.c, the resource_size_t is 32bit
| variable in 32bit OS, the BUG_ON() will be invoked to result in the Int 6
| error. I try the latest 32bit Ubuntu and Fedora distributions, all hit this
| bug.
|======
|static int firmware_map_add_entry(resource_size_t start, resource_size_t end,
|                  const char *type,
|                  struct firmware_map_entry *entry)

and it only happen with CONFIG_PHYS_ADDR_T_64BIT is not set.

it turns out we need to pass u64 instead of resource_size_t for that.

Arnd Bergmann 08604bd993 time: move PIT_TICK_RATE to linux/timex.h
PIT_TICK_RATE is currently defined in four architectures, but in three
different places.  While linux/timex.h is not the perfect place for it, it
is still a reasonable replacement for those drivers that traditionally use
asm/timex.h to get CLOCK_TICK_RATE and expect it to be the PIT frequency.

Note that for Alpha, the actual value changed from 1193182UL to 1193180UL.
 This is unlikely to make a difference, and probably can only improve
accuracy.  There was a discussion on the correct value of CLOCK_TICK_RATE
a few years ago, after which every existing instance was getting changed
to 1193182.  According to the specification, it should be
1193181.818181...

Thanks, but it turns out I hit a 32 bit integer overflow in
the gain calculation. I'd like to mend that with the following
patch. Now max_uV could be increased up to 4.294 V, enough to
charge LiPo cells.

Philipp Zabel b110a8fb24 regulator/max1586: support increased V3 voltage range
The V3 regulator can be configured with an external resistor
connected to the feedback pin (R24 in the data sheet) to
increase the voltage range.

For example, hx4700 has R24 = 3.32 kOhm to achieve a maximum
V3 voltage of 1.55 V which is needed for 624 MHz CPU frequency.

Greg Kroah-Hartman 1909e2f658 regulator: remove driver_data direct access of struct device
In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device.  Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used.  These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

Regulators need to be available early in init in order to allow them

by registering them at subsys_initcall() time but not all regulator
drivers have done that. Convert these drivers to do so in order to

The current build shows a warning with the DTL-1 driver:

  CC [M]  drivers/bluetooth/dtl1_cs.o
drivers/bluetooth/dtl1_cs.c: In function ‘dtl1_hci_send_frame’:
drivers/bluetooth/dtl1_cs.c:396: warning: ‘nsh.type’ may be used uninitialized in this function

Fix this by adding a proper error for unknown packet types.

Randy Dunlap 13be8a1268 ieee802154: fix kconfig bool/tristate muckup
menuconfig IEEE802154_DRIVERS is a bool that depends on tristate IEEE802154.
If the IEEE802154 symbol is 'm', the bool becomes 'y'.
This allows tristate symbols under IEEE802154_DRIVERS to be configured as
'y' and cause build problems.
Changing the menuconfig bool to a tristate fixes this.

Stephen Hemminger 373500db92 bonding: network device names are case sensative
The bonding device acts unlike all other Linux network device functions
in that it ignores case of device names. The developer must have come
from windows!

Cleanup the management of names and use standard routines where possible.
Flag places where bonding device still doesn't work right with network
namespaces.

It is not safe to use a network device destructor that is a function in

handle is open.

When eventually using netlink, the device cleanup code needs to be done

When both MSI-X and legacy INTx fail to generate an interrupt, the
driver frees the MSI-X interrupts twice.  Fix this by clearing the
have_irq flag for the MSI-X interrupts when they are freed the first
time.

Ben Dooks 051913dada mmc_block: do not DMA to stack
In the write recovery routine, the data to get from the card
is allocated from the stack. The DMA mapping documentation says
explicitly stack memory is not mappable by any of the DMA calls.

Change to using kmalloc() to allocate the memory for the result
from the card and then free it once we've finished with the
transaction.

Ian Molton da46a0bd42 tmio_mmc: fix clock setup
This patch fixes the clock setup in tmio_mmc.

  * Incorrect divider setting
  * Cruft written to the clock registers (seemingly harmless but Not
Good (tm))

It also eliminates some unnecessary ifs and tidies the loop syntax.

Thanks to Philipp Zabel who discovered the divider issue, commenting

   "Except for the SDCLK = HCLK (divider bypassed) case, the clock
    setting resulted in double the requested frequency.
    The smallest possible frequency (f_max/512) is configured with
    a divider setting 0x80, not 0x40."
