Enable capture from line-in and CD on the Revolution 5.1 card.
This patch adds support for switching between the 5 input channels of
the AK5365 ADC and modifies the Revolution 5.1 driver to make use of
this facility. Previously the capture channel was fixed to channel 0
(microphone on the Revolution 5.1 card).

Rename the 'us_regs' field of the ucc_slow_info structure in ucc_slow.h

also called 'regs', so this patch makes them comparable, and makes the

ehash table layout is currently this one :
First half of this table is used by sockets not in TIME_WAIT state
Second half of it is used by sockets in TIME_WAIT state.
This is non optimal because of for a given hash or socket, the two chain heads
are located in separate cache lines.
Moreover the locks of the second half are never used.
If instead of this halving, we use two list heads in inet_ehash_bucket instead
of only one, we probably can avoid one cache miss, and reduce ram usage,
particularly if sizeof(rwlock_t) is big (various CONFIG_DEBUG_SPINLOCK,
CONFIG_DEBUG_LOCK_ALLOC settings). So we still halves the table but we keep
together related chains to speedup lookups and socket state change.
In this patch I did not try to align struct inet_ehash_bucket, but a future
patch could try to make this structure have a convenient size (a power of two
or a multiple of L1_CACHE_SIZE).
I guess rwlock will just vanish as soon as RCU is plugged into ehash :) , so
maybe we dont need to scratch our heads to align the bucket...
Note : In case struct inet_ehash_bucket is not a power of two, we could
probably change alloc_large_system_hash() (in case it use __get_free_pages())
to free the unused space. It currently allocates a big zone, but the last
quarter of it could be freed. Again, this should be a temporary 'problem'.
Patch tested on ipv4 tcp only, but should be OK for IPV6 and DCCP.

Move DSACK code outside the SACK fast-path checking code. If the DSACK
determined that the information was too old we stayed with a partial cache
copied. Most likely this matters very little since the next packet will not be
DSACK and we will find it in the cache. but it's still not good form and there
is little reason to couple the two checks.
Since the SACK receive cache doesn't need the data to be in host order we also
remove the ntohl in the checking loop.

This patch is needed to make ISC's DHCP server (and probably other
DHCP servers/clients using AF_PACKET) to be able to serve another
client on the same Xen host.
The problem is that packets between different domains on the same
Xen host only have partial checksums. Unfortunately this piece of
information is not passed along in AF_PACKET unless you're using
the mmap interface. Since dhcpd doesn't support packet-mmap, UDP
packets from the same host come out with apparently bogus checksums.
This patch adds a mechanism for AF_PACKET recvmsg(2) to return the
status along with the packet. It does so by adding a new cmsg that
contains this information along with some other relevant data such
as the original packet length.
I didn't include the time stamp information since there is already
a cmsg for that.
This patch also changes the mmap code to set the CSUMNOTREADY flag
on all packets instead of just outoing packets on cooked sockets.

The Atmel AT91 and AVR32 processor architectures share many of the same
peripherals. The PDC (Peripheral Data Controller) registers are also
implemented within in a number of the on-chip peripherals (eg, USART,
MMC, SPI, SSC, etc).
In a attempt not to duplicate the register definitions in each
peripheral, or in each architecture, the at91_pdc.h header in
asm-arm/arch-at91 and asm-avr32/arch-at32ap has been replaced with
linux/atmel_pdc.h.
The definitions have also been renamed from AT91_PDC_* to ATMEL_PDC_*,
and the drivers updated accordingly.

This patch renames pxa_gpio_set/get functions defined in drivers/usb/gadget/pxa2xx_udc.h to udc_gpio_set/get.
These functions are moved from drivers/usb/gadget/pxa2xx_udc.h to include/asm-arm/arch-pxa2xx/udc.h
Creates new functions: udc_gpio_to_irq, udc_gpio_init_vbus, udc_gpio_init_pullup in include/asm-arm/arch-pxa2xx/udc.h. These functions are used in drivers/usb/gadget/pxa2xx_udc.c instead of direct low-level (pxa2xx only) functions.
Creates all these udc_gpio_* functions in include/asm-arm/arch-ixp4xx/udc.h. This implementation has no real code because ixp4xx doesn't use vbus - only vbus uses all these gpio functions (and because ixp4xx misses any function which converts number of gpio pin into it's irq).
This is next step to make pxa2xx_udc fully work on ixp4xx platform.

The Atmel AT91SAM9263 processor includes many more integrated
peripherals than Atmel's previous ARM9-based AT91 processors, so this
has necessitated a few changes to the core AT91 support.
These changes are:
* The system peripheral I/O region we remap has increased from
0xFFFA0000..0xFFFFFFFF to 0xFFF78000..0xFFFFFFFF.
* The increased I/O region forces changes to entry-macro.S and
debug-macro.S due to ARM's limited immediate offset addressing
modes.
* Maximum number of GPIO banks increases to 5.
* 2 MMC controllers so the board-setup code needs to specify which
controller it wishes to use when calling at91_add_device_mmc().

Fix build failure of AT91SAM9260.
The AT91RM9200 ethernet driver (at91_ether.c) stores platform data in a
"struct at91_eth_data" structure, but the AT91SAM9260 (and AT91SAM9263)
ethernet driver (macb.c) [developed on the AVR32 architecture] expects a
"struct eth_platform_data".
Since the platform data of the two drivers is very similar, we continue
to use the "struct at91_eth_data" for all AT91 processors but add a
#define eth_platform_data at91_eth_data
in board.h to keep the MACB driver happy.
