This reverts commit e86ff4a63c.
This tried to enforce the semantics of one interrupt per iir read of the
THRE (transmit-hold empty) status, but events from other sources
(particularly modem status) defeat this guarantee.
This change also broke 8250_pci suspend/resume support as
pciserial_resume_ports() re-runs .init() quirks, but does not run
.exit() quirks in pciserial_suspend_ports() leading to reports like:
sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:16.3/msi_irqs'
...and a subsequent crash. The mismatch of init/exit at suspend/resume
seems like a bug in its own right.

On our custom board, we are using RS485 in half-duplex mode on an AT91SAM9G45.
SER_RS485_RX_DURING_TX is not set as we do not want to receive the data we
transmit (our transceiver will receive transmitted data).
Although the current driver attempts to disable and enable the receiver at the
appropriate points, incoming data is still loaded into the receive register
causing our code to receive the very last byte that was sent once the receiver
is enabled.
I ran this by Atmel support and they wrote: "The issue comes from the fact
that you disable the PDC/DMA Reception and not the USART Reception channel. In
your case, the[n] you will still receive data into the USART_RHR register, and
maybe you [h]ave the overrun flag set. So please disable the USART reception
channel."
The following patch should force the driver to enable/disable the receiver via
RXEN/RXDIS fields of the USART control register. It fixed the issue I was
having.

The driver frees the clock samples buffer before stopping the video
buffers queue. If a DQBUF call arrives in-between,
uvc_video_clock_update() will be called with a NULL clock samples
buffer, leading to a crash. This occurs very frequently when using the
webcam with the flash browser plugin.
Move clock initialization/cleanup to uvc_video_enable() in order to free
the clock samples buffer after the queue is stopped. Make sure the clock
is reset at resume time to avoid miscalculating timestamps.

No, this is the correct patch:
RADIO_MAXIRADIO should be treated just like RADIO_SF16FMR2, I just didn't

The commit e399ce77e6 has broken the DVB ABI for xine:
The problem is that xine is expecting every event after a successful
FE_SET_FRONTEND ioctl to have a non-zero frequency parameter, regardless
of whether the tuning process has LOCKed yet. What used to happen is
that the events inherited the initial tuning parameters from the
FE_SET_FRONTEND call. However, the fepriv->parameters_out struct is now
not initialised until the status contains the FE_HAS_LOCK bit.
You might argue that this behaviour is intentional, except that if an
application other than xine uses the DVB adapter and manages to set the
parameters_out.frequency field to something other than zero, then xine
no longer has any problems until either the adapter is replugged or the
kernel modules reloaded. This can only mean that the
fepriv->parameters_out struct still contains the (stale) tuning
information from the previous application.

Add abort flag and use it to terminate processing when an exchange
is timed out or is reset. The abort flag is used in place of the
transport_generic_free_cmd function call in the reset and timeout
cases, because calling that function in that context would free
memory that was in use. The aborted flag allows the lifetime to
be managed in a more normal way, while truncating the processing.
This change eliminates a source of memory corruption which
manifested in a variety of ugly ways.

Pull xen fixes from Konrad Rzeszutek Wilk:
"Two fixes for regressions:
* one is a workaround that will be removed in v3.5 with proper fix in
the tip/x86 tree,
* the other is to fix drivers to load on PV (a previous patch made
them only load in PVonHVM mode).
The rest are just minor fixes in the various drivers and some cleanup
in the core code."
* tag 'stable/for-linus-3.4-rc1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen:
xen/pcifront: avoid pci_frontend_enable_msix() falsely returning success
xen/pciback: fix XEN_PCI_OP_enable_msix result
xen/smp: Remove unnecessary call to smp_processor_id()
xen/x86: Workaround 'x86/ioapic: Add register level checks to detect bogus io-apic entries'
xen: only check xen_platform_pci_unplug if hvm
The major fixes here are:
* Disable use of MSI in sdhci-pci, which caused multiple chipsets to
stop working in 3.4-rc1. I'll wait to turn this on again until we
have a chipset whitelist for it.
* Fix a libertas SDIO powered-resume regression introduced in 3.3;
thanks to Neil Brown and Rafael Wysocki for this fix.
* Fix module reloading on omap_hsmmc.
* Stop trusting the spec/card's specified maximum data timeout length,
and use three seconds instead. Previously we used 300ms.
Also cleanups and fixes for s3c, atmel, sh_mmcif and omap_hsmmc.

Commit 360f748b204275229f8398cb2f9f53955db1503b
"serial: PL011: clear pending interrupts"
attempts to clear interrupts by writing to a
yet-unassigned memory address. This fixes the issue.
The breaking patch is marked for stable so should be
carried along with the other patch.

I have a new optimized x86 "strncpy_from_user()" that will use these
same helper functions for all the same reasons the name lookup code uses
them. This is preparation for that.
This moves them into an architecture-specific header file. It's
architecture-specific for two reasons:
- some of the functions are likely to want architecture-specific
implementations. Even if the current code happens to be "generic" in
the sense that it should work on any little-endian machine, it's
likely that the "multiply by a big constant and shift" implementation
is less than optimal for an architecture that has a guaranteed fast
bit count instruction, for example.
- I expect that if architectures like sparc want to start playing
around with this, we'll need to abstract out a few more details (in
particular the actual unaligned accesses). So we're likely to have
more architecture-specific stuff if non-x86 architectures start using
this.
(and if it turns out that non-x86 architectures don't start using
this, then having it in an architecture-specific header is still the
right thing to do, of course)
