Since target allocations can occur while resetting the virtual adapter,
we shouldn't be using GFP_KERNEL for them as it could hang. Switch to
use GFP_NOIO.

The async split up of probing in sd.c created a potential failure case where
something goes wrong with device_add(), but which we don't recover properly.
Since, in general, asynchronous error handling is hard, move the device_add()
into the asynchronous path (it should be fast) and make sure all the deferred
processing cannot fail.

The Documentation is incorrect (we removed some functions referred to), and
none of the bug warnings now apply. Additionally remove the spurious check on
the return from blk_get_request() which can't fail if __GFP_WAIT is passed in.

Using gcc 3.3.5 a "make allmodconfig" + "CONFIG_KVM=n"
triggers a build error:
arch/x86/mm/built-in.o(.init.text+0x43f7): In function `__change_page_attr':
arch/x86/mm/pageattr.c:114: undefined reference to `__udivdi3'
make: *** [.tmp_vmlinux1] Error 1
The culprit turned out to be a division in arch/x86/mm/memtest.c
For more info see this thread:
http://marc.info/?l=linux-kernel&m=124416232620683
The patch entirely removes the division that caused the build
error.
[ Impact: build fix with certain GCC versions ]

Added boot quirk for C-Media CM6206 device in snd_usb_audio_probe.
The function snd_usb_cm6206_boot_quirk sets up six internal 16-bit
registers in order to initialize the device. Values for the registers
came from sniffing USB traffic under Windows since only four of the six
are documented in the datasheet for CM106 and some reserved bits were
also being set.

Fix bug in the SGI UV macros that support systems with multiple
coherency domains. The macros used for referencing global MMR
(chipset registers) are failing to correctly "or" the NASID
(node identifier) bits that reside above M+N. These high bits
are supplied automatically by the chipset for memory accesses
coming from the processor socket.
However, the bits must be present for references to the special
global MMR space used to map chipset registers. (See uv_hub.h
for more details ...)
The bug results in references to invalid/incorrect nodes.

The dx_map_entry structure doesn't support over 64KB block size by
current usage of its member("offs"). Because "offs" treats an offset
of copies of the ext4_dir_entry_2 structure as is. This member size is
16 bits. But real offset for over 64KB(256KB) block size needs 18
bits. However, real offset keeps 4 byte boundary, so lower 2 bits is
not used.
Therefore, we do the following to fix this limitation:
For "store":
we divide the real offset by 4 and then store this result to "offs"
member.
For "use":
we multiply "offs" member by 4 and then use this result
as real offset.

Adds support for the new queues in the SLI-4 interface. There are :
- Work Queues - host-to-adapter for fast-path traffic
- Mailbox Queues - host-to-adapter for control (slow-path)
- Buffer Queues - host-to-adapter for posting buffers for async receive
- Completion Queues - adapter-to-host for posting async events,
completions for fast or slow patch work, receipt of async
receive traffic
- Event Queues - tied to MSI-X vectors, binds completion queues with
interrupts
These patches add the all the support code to tie into command submission
and response paths, updates the interrupt handling, etc.

Preps the organization of the driver so that the bottom half, which
interacts with the hardware, can share common code sequences for
attachment, detachment, initialization, teardown, etc with new hardware.
For very common code sections, which become specific to the interface
type, the driver uses an indirect function call. The function is set at
initialization. For less common sections, such as initialization, the
driver looks at the interface type and calls the routines relative to
the interface.

Outlining fixes the issue were on certain CPUs such as the R10000 family
the delay loop would need an extra cycle if it overlaps a cacheline
boundary.
The rewrite also fixes build errors with GCC 4.4 which was changed in
way incompatible with the kernel's inline assembly.
Relying on pure C for computation of the delay value removes the need for
explicit. The price we pay is a slight slowdown of the computation - to
be fixed on another day.
