The PCI and PCMCIA LabPC boards use shared interrupts and need the
IRQF_SHARED flag set when requesting the irq, the ISA boards do not.
Instead of checking the 'bustype' in labpc_common_attach() in order
to determine the isr_flags, just pass the flags as a parameter to the
function.

Currently the ni_labpc driver is used by the legacy (ISA), PCI, and
PCMCIA versions of the LabPC board. The driver is enabled under the
COMEDI_PCI_DRIVERS section of the Kconfig. This means that PCI support
must be enabled in order to use the ni_labpc driver for the PCI or
PCMCIA drivers.
Split the PCI support code out of the ni_labpc driver into a separate
driver, ni_labpc_pci. The PCMCIA support is already slip out as
ni_labpc_cs.
Modify the Kconfig so that the common code in ni_labpc is enabled by the
Kconfig option COMEDI_NI_LABPC. The ISA support code is currently still
in the ni_labpc driver but is only compiled in if COMEDI_NI_LABPC_ISA is
also enabled.
This allows the PCI and PCMCIA drivers to be enabled without the need
for the ISA stuff.

On ARM, it is not legal to pass values larger than 2ms into udelay(),
and mdelay() must be used instead, to avoid this build error:
ERROR: "__bad_udelay" [drivers/staging/comedi/drivers/daqboard2000.ko]
undefined!
On a related note, any use of mdelay() or large udelay() numbers should
be carefully reviewed, and replaced with msleep() or a different
implementation that does not rely on delaying the work.

Building zsmalloc as a module does not work on ARM because it uses
an interface that is not exported:
ERROR: "flush_tlb_kernel_range" [drivers/staging/zsmalloc/zsmalloc.ko] undefined!
Since this is only used as a performance optimization and only on ARM,
we can avoid the problem simply by not using that optimization when
building zsmalloc it is a loadable module.
flush_tlb_kernel_range is often an inline function, but out of the
architectures that use an extern function, only powerpc exports
it.

This driver was merged in 2.6.38 but never actually compiled because
it depends on the <mach/pcie.h> header that has not made it into the
kernel. Starting with Linux-3.10, this results in "allyesconfig"
build errors, since spear13xx can now be enabled with the default
"multiplatform" platform on ARM. Let's mark it as broken for now.
If it doesn't get fixed, we can drop it completely.

A lot of platform code calls into the usb phy core at the moment, which
does not work if it is built as a loadable module. This will hopefully
change when those platforms are all converted to DT based probing,
but for now, the easiest solution is to change it from "tristate"
to "bool".
This solves at least these ARM allmodconfig build errors:

Many cards based on CY7C68300A/B/C use the USB ID 04b4:6830 but only the
B and C variants (EZ-USB AT2LP) support the ATA Command Block
functionality, according to the data sheets. The A variant (EZ-USB AT2)
locks up if ATACB is attempted, until a typical 30 seconds timeout runs
out and a USB reset is performed.
https://bugs.launchpad.net/bugs/428469
It seems that one way to spot a CY7C68300A (at least where the card
manufacturer left Cypress' EEPROM default vaules, against Cypress'
recommendations) is to look at the USB string descriptor indices.
A http://media.digikey.com/pdf/Data%20Sheets/Cypress%20PDFs/CY7C68300A.pdf
B http://www.farnell.com/datasheets/43456.pdf
C http://www.cypress.com/?rID=14189
Note that a CY7C68300B/C chip appears as CY7C68300A if it is running
in Backward Compatibility Mode, and if ATACB would be supported in this
case there is anyway no way to tell which chip it really is.
For 5 years my external USB drive has been locking up for half a minute
when plugged in and ata_id is run by udev, or anytime hdparm or similar
is run on it.
Finally looking at the /correct/ datasheet I think I found the reason. I
am aware the quirk in this patch is a bit hacky, but the hardware
manufacturers haven't made it easy for us.

The current ST Micro Connect Lite uses the FT4232H hi-speed quad USB
UART FTDI chip. It is also possible to drive STM reference targets

the same STMicroelectronics tools.
For this reason, the ST Micro Connect Lite PIDs should be
ST_STMCLT_2232_PID: 0x3746
ST_STMCLT_4232_PID: 0x3747

usb: urgent fixes for v3.10 merge window
Here are some late urgent fixes for v3.10 merge window.
All of these errors were introduced by recent commits
which are in linux-next.
f_obex, multi and cdc2 gadget drivers have learned to
return a proper error code when something goes wrong.
usb_bind_phy() was mistakenly placed into .init.text
section which caused Section mismatch warnings and undefined
reference compile errors.
f_source_sink had a copy-paste error which is now corrected.
g_zero got a memory leak plugged.
Two defconfigs got fixed to enable the newly introduced
CONFIG_USB_PHY.

Due to a missing cast, the high 32-bits of a 64-bit block number used
when calculating the readahead block for inode tables can get lost.
This means we can end up fetching the wrong blocks for readahead for

Linus found this when experimenting with an enhacement to the sparse
