rt2x00: error in configurations with mesh support disabled

2013-03-28T19:18:14+00:00

commit 6ef9e2f6d12ce9e2120916804d2ddd46b954a70b upstream.

If CONFIG_MAC80211_MESH is not set, cfg80211 will now allow advertising
interface combinations with NL80211_IFTYPE_MESH_POINT present.
Add appropriate ifdefs to avoid running into errors.

[Backported for 3.8-stable. Removed code of simultaneous AP and mesh
mode added in 4a5fc6d 3.9-rc1.]

ARM: DMA-mapping: add missing GFP_DMA flag for atomic buffer allocation

2013-03-28T19:18:14+00:00

commit 9d1400cf79afb49584b4873eb22cd5130cb341db upstream.

Atomic pool should always be allocated from DMA zone if such zone is
available in the system to avoid issues caused by limited dma mask of
any of the devices used for making an atomic allocation.

USB: io_ti: fix get_icount for two port adapters

2013-03-28T19:18:14+00:00

commit 5492bf3d5655b4954164f69c02955a7fca267611 upstream.

Add missing get_icount field to two-port driver.

The two-port driver was not updated when switching to the new icount
interface in commit 0bca1b913aff ("tty: Convert the USB drivers to the
new icount interface").

USB: garmin_gps: fix memory leak on disconnect

2013-03-28T19:18:14+00:00

commit 618aa1068df29c37a58045fe940f9106664153fd upstream.

Remove bogus disconnect test introduced by 95bef012e ("USB: more serial
drivers writing after disconnect") which prevented queued data from
being freed on disconnect.

The possible IO it was supposed to prevent is long gone.

udf: Fix bitmap overflow on large filesystems with small block size

2013-03-28T19:18:14+00:00

commit 89b1f39eb4189de745fae554b0d614d87c8d5c63 upstream.

For large UDF filesystems with 512-byte blocks the number of necessary
bitmap blocks is larger than 2^16 so s_nr_groups in udf_bitmap overflows
(the number will overflow for filesystems larger than 128 GB with
512-byte blocks). That results in ENOSPC errors despite the filesystem
has plenty of free space.

Fix the problem by changing s_nr_groups' type to 'int'. That is enough
even for filesystems 2^32 blocks (UDF maximum) and 512-byte blocksize.

ACPI: Rework acpi_get_child() to be more efficient

2013-03-28T19:18:14+00:00

commit 33f767d767e9a684e9cd60704d4c049a2014c8d5 upstream.

Observe that acpi_get_child() doesn't need to use the helper
struct acpi_find_child structure and change it to work without it.
Also, using acpi_get_object_info() to get the output of _ADR for the
given device is overkill, because that function does much more than
just evaluating _ADR (let alone the additional memory allocation
done by it).

Moreover, acpi_get_child() doesn't need to loop any more once it has
found a matching handle, so make it stop in that case.  To prevent
the results from changing, make it use do_acpi_find_child() as
a post-order callback.

efivars: Add module parameter to disable use as a pstore backend

2013-03-28T19:18:13+00:00

commit ec0971ba5372a4dfa753f232449d23a8fd98490e upstream.

We know that with some firmware implementations writing too much data to
UEFI variables can lead to bricking machines. Recent changes attempt to
address this issue, but for some it may still be prudent to avoid
writing large amounts of data until the solution has been proven on a
wide variety of hardware.

Crash dumps or other data from pstore can potentially be a large data
source. Add a pstore_module parameter to efivars to allow disabling its
use as a backend for pstore. Also add a config option,
CONFIG_EFI_VARS_PSTORE_DEFAULT_DISABLE, to allow setting the default
value of this paramter to true (i.e. disabled by default).
