btrfs: don't stop searching after encountering the wrong item

commit 03b71c6ca6286625d8f1ed44aabab9b5bf5dac10 upstream.

The search ioctl skips items that are too large for a result buffer, but
inline items of a certain size occuring before any search result is
found would trigger an overflow and stop the search entirely.

i2c: designware: always clear interrupts before enabling them

commit 2a2d95e9d6d29e726cc294b65391917ed2e32bf4 upstream.

If the I2C bus is put to a low power state by an ACPI method it might pull
the SDA line low (as its power is removed). Once the bus is put to full
power state again, the SDA line is pulled back to high. This transition
looks like a STOP condition from the controller point-of-view which sets
STOP detected bit in its status register causing the driver to fail
subsequent transfers.

Fix this by always clearing all interrupts before we start a transfer.

media: mantis: fix silly crash case

commit e1d45ae10aea8e8a403e5d96bf5902ee670007ff upstream.

If we set mantis->fe to NULL on an error its not a good idea to then try
passing NULL to the unregister paths and oopsing really.

Linux 3.4.47
xen-pciback: rate limit error messages from xen_pcibk_enable_msi{,x}()

... as being guest triggerable (e.g. by invoking
XEN_PCI_OP_enable_msi{,x} on a device not being MSI/MSI-X capable).

This is CVE-2013-0231 / XSA-43.

Also make the two messages uniform in both their wording and severity.
