hwmon: (coretemp) Add missing newline to dev_warn() message

2010-04-01T22:56:00+00:00

commit 4d7a5644e4adfafe76c2bd8ee168e3f3b5dae3a8 upstream.

Add missing newline to dev_warn() message string. This is more of an issue
with older kernels that don't automatically add a newline if it was missing
from the end of the previous line.

x86: Fix placement of FIX_OHCI1394_BASE

2010-04-01T22:56:00+00:00

commit ff30a0543e9a6cd732582063e7cae951cdb7acf2 upstream.

Ever for 32-bit with sufficiently high NR_CPUS, and starting
with commit 789d03f584484af85dbdc64935270c8e45f36ef7 also for
64-bit, the statically allocated early fixmap page tables were
not covering FIX_OHCI1394_BASE, leading to a boot time crash
when "ohci1394_dma=early" was used. Despite this entry not being
a permanently used one, it needs to be moved into the permanent
range since it has to be close to FIX_DBGP_BASE and
FIX_EARLYCON_MEM_BASE.

USB: fix usbfs regression

2010-04-01T22:56:00+00:00

commit 7152b592593b9d48b33f8997b1dfd6df9143f7ec upstream.

This patch (as1352) fixes a bug in the way isochronous input data is
returned to userspace for usbfs transfers.  The entire buffer must be
copied, not just the first actual_length bytes, because the individual
packets will be discontiguous if any of them are short.

doc: add the documentation for mpol=local

2010-04-01T22:55:59+00:00

commit 5574169613b40b85d6f4c67208fa4846b897a0a1 upstream.

commit 3f226aa1c (mempolicy: support mpol=local tmpfs mount option) added
new mpol=local mount option.  but it didn't add a documentation.

This patch does it.

tmpfs: cleanup mpol_parse_str()

2010-04-01T22:55:59+00:00

commit 926f2ae04f183098cf9a30521776fb2759c8afeb upstream.

mpol_parse_str() made lots 'err' variable related bug.  Because it is ugly
and reviewing unfriendly.

This patch simplifies it.

tmpfs: handle MPOL_LOCAL mount option properly

2010-04-01T22:55:59+00:00

commit 12821f5fb942e795f8009ece14bde868893bd811 upstream.

commit 71fe804b6d5 (mempolicy: use struct mempolicy pointer in
shmem_sb_info) added mpol=local mount option.  but its feature is broken
since it was born.  because such code always return 1 (i.e.  mount
failure).

This patch fixes it.

tmpfs: mpol=bind:0 don't cause mount error.

2010-04-01T22:55:58+00:00

commit d69b2e63e9172afb4d07c305601b79a55509ac4c upstream.

Currently, following mount operation cause mount error.

% mount -t tmpfs -ompol=bind:0 none /tmp

Because commit 71fe804b6d5 (mempolicy: use struct mempolicy pointer in
shmem_sb_info) corrupted MPOL_BIND parse code.

This patch restore the needed one.

tmpfs: fix oops on mounts with mpol=default

2010-04-01T22:55:58+00:00

commit 413b43deab8377819aba1dbad2abf0c15d59b491 upstream.

Fix an 'oops' when a tmpfs mount point is mounted with the mpol=default
mempolicy.

Upon remounting a tmpfs mount point with 'mpol=default' option, the mount
code crashed with a null pointer dereference.  The initial problem report
was on 2.6.27, but the problem exists in mainline 2.6.34-rc as well.  On
examining the code, we see that mpol_new returns NULL if default mempolicy
was requested.  This 'NULL' mempolicy is accessed to store the node mask
resulting in oops.

The following patch fixes it.

V4L/DVB (13961): em28xx-dvb: fix memleak in dvb_fini()

2010-04-01T22:55:58+00:00

commit 19f48cb105b7fa18d0dcab435919a3a29b7a7c4c upstream.

this patch fixes a memory leak which occurs when an em28xx card with DVB
extension is unplugged or its DVB extension driver is unloaded. In
dvb_fini(), dev->dvb must be freed before being set to NULL, as is done
in dvb_init() in case of error.
Note that this bug is also present in the latest stable kernel release.
