The reason we are dying is b/c the call acpi_get_override_irq() is used,
which returns the polarity and trigger for the IRQs. That function calls
mp_find_ioapics to get the 'struct ioapic' structure - which along with the
mp_irq[x] is used to figure out the default values and the polarity/trigger
overrides. Since the mp_find_ioapics now returns -1 [b/c the IOAPIC is filled
with 0xffffffff], the acpi_get_override_irq() stops trying to lookup in the
mp_irq[x] the proper INT_SRV_OVR and we can't install the SCI interrupt.
The proper fix for this is going in v3.5 and adds an x86_io_apic_ops
struct so that platforms can override it. But for v3.4 lets carry this
work-around. This patch does that by providing a slightly different variant
of the fake IOAPIC entries.

A bunch of fixes for regressions (and a few other problems) in 3.4-rc1:

(adding back the include file on those for now)
* AT91 fixes for usb and spi
* smsc911x ethernet fixes for i.MX
* smsc911x fixes for OMAP
* gpio fixes for Tegra
* A handful of build error and warning fixes for various platforms
* cpufreq kconfig dependencies, build and lowlevel debug fixes for
Samsung platforms
In other words, more or less the regular collection of -rc1/2 type
material. A few of them, in particular the smsc911x for OMAP series, aren't
technically regressions for 3.4, but they're valid fixes and we're still
relatively early in the rc cycle so it seems appropriate to include them.

Several people have noticed that crappy SD cards take much longer to
complete multiple block writes than the 300ms that Linux specifies.
Try to work around this by using a three second write timeout instead.
This is a generalized version of a patch from Chase Maupin
<Chase.Maupin@ti.com>, whose patch description said:
* With certain SD cards timeouts like the following have been seen
due to an improper calculation of the dto value:
mmcblk0: error -110 transferring data, sector 4126233, nr 8,
card status 0xc00
* By removing the dto calculation and setting the timeout value
to the maximum specified by the SD card specification part A2
section 2.2.15 these timeouts can be avoided.
* This change has been used by beagleboard users as well as the
Texas Instruments SDK without a negative impact.
* There are multiple discussion threads about this but the most
relevant ones are:
* http://talk.maemo.org/showthread.php?p=1000707#post1000707
* http://www.mail-archive.com/linux-omap@vger.kernel.org/msg42213.html

The driver should not try to switch to 1.8V when the SD 3.0 host
controller does not have any UHS capabilities bits set (SDR50, DDR50
or SDR104). See page 72 of "SD Specifications Part A2 SD Host
Controller Simplified Specification Version 3.00" under
"1.8V Signaling Enable". Instead of setting SDR12 and SDR25 in the host
capabilities data structure for all V3.0 host controllers, only set them
if SDR104, SDR50 or DDR50 is set in the host capabilities register. This
will prevent the switch to 1.8V later.

mmc_select_powerclass() function returns error if eMMC
VDD level supported by host is between 2.7v to 3.2v.
According to eMMC specification, valid voltage for high
voltage cards is 2.7v to 3.6v. This patch ensures that
2.7v to 3.6v VDD range is treated as valid range.
Also, failure to set the power class shouldn't be treated
as fatal error because even if setting the power class
fails, card can still work in default power class.
If mmc_select_powerclass() returns error, just print
the warning message and go ahead with rest of the card

Neil Brown reports that commit 35cd133c
PM: Run the driver callback directly if the subsystem one is not there
breaks suspend for his libertas wifi, because SDIO has a protocol
where the suspend method can return -ENOSYS and this means "There is
no point in suspending, just turn me off". Moreover, the suspend
methods provided by SDIO drivers are not supposed to be called by
the PM core or bus-level suspend routines (which aren't presend for
SDIO). Instead, when the SDIO core gets to suspend the device's
ancestor, it calls the device driver's suspend function, catches the
ENOSYS, and turns the device off.
The commit above breaks the SDIO core's assumption that the device
drivers' callbacks won't be executed if it doesn't provide any
bus-level callbacks. If fact, however, this assumption has never
been really satisfied, because device class or device type suspend
might very well use the driver's callback even without that commit.
The simplest way to address this problem is to make the SDIO core
tell the PM core to ignore driver callbacks, for example by providing
no-operation suspend/resume callbacks at the bus level for it,
which is implemented by this change.

The various devm_ functions allocate memory that is released when a driver
detaches. This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.
By using devm_ioremap, it also removes a potential memory leak, because
there was no call to iounmap in the probe function.
The call to platform_get_resource was moved just to make it closer to the
place where its result it used.

Merge tag 'omap-fixes-a2-for-3.4rc' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into fixes
From Paul Walmsley:
OMAP clock, powerdomain, clockdomain, and hwmod fixes intended for the
early v3.4-rc series. Also contains an HSMMC integration refinement
of an earlier hardware bug workaround.

The platform data is copied into driver's private data and the copy is
used for all access to the platform data. This simpifies the addition
of device tree support for the sdhci-s3c driver.

max_width member in platform data can be used to derive the mmc bus transfer
width that can be supported by the controller.

SDHCI controllers on Exynos4 do not include the sdclk divider as per the
sdhci controller specification. This case can be represented using the
sdhci quirk SDHCI_QUIRK_NONSTANDARD_CLOCK instead of using an additional
enum type definition 'clk_types'.
Hence, usage of clk_type member in platform data is removed and the sdhci
quirk is used. In addition to that, since this qurik is SoC specific,
driver data is introduced to represent controllers on SoC's that require
this quirk.

When a slave comes up, we're unsetting the current_arp_slave without
removing active flags from it, which can lead to situations where we have
more than one slave with active flags in active-backup mode.
To avoid this situation we must remove the active flags from a slave before
removing it as a current_arp_slave.

commit 2f53384424 (tcp: allow splice() to build full TSO packets) added
a regression for splice() calls using SPLICE_F_MORE.
We need to call tcp_flush() at the end of the last page processed in
tcp_sendpages(), or else transmits can be deferred and future sends
stall.
Add a new internal flag, MSG_SENDPAGE_NOTLAST, acting like MSG_MORE, but
with different semantic.
For all sendpage() providers, its a transparent change. Only
sock_sendpage() and tcp_sendpages() can differentiate the two different
flags provided by pipe_to_sendpage()

Merge batch of fixes from Andrew Morton:
"The simple_open() cleanup was held back while I wanted for laggards to
merge things.
I still need to send a few checkpoint/restore patches. I've been
wobbly about merging them because I'm wobbly about the overall
prospects for success of the project. But after speaking with Pavel
at the LSF conference, it sounds like they're further toward
completion than I feared - apparently davem is at the "has stopped
complaining" stage regarding the net changes. So I need to go back
and re-review those patchs and their (lengthy) discussion."
