memcg: oom: fix totalpages calculation for memory.swappiness==0

2012-11-26T19:37:45+00:00

commit 9a5a8f19b43430752067ecaee62fc59e11e88fa6 upstream.

oom_badness() takes a totalpages argument which says how many pages are
available and it uses it as a base for the score calculation.  The value
is calculated by mem_cgroup_get_limit which considers both limit and
total_swap_pages (resp.  memsw portion of it).

This is usually correct but since fe35004fbf9e ("mm: avoid swapping out
with swappiness==0") we do not swap when swappiness is 0 which means
that we cannot really use up all the totalpages pages.  This in turn
confuses oom score calculation if the memcg limit is much smaller than
the available swap because the used memory (capped by the limit) is
negligible comparing to totalpages so the resulting score is too small
if adj!=0 (typically task with CAP_SYS_ADMIN or non zero oom_score_adj).
A wrong process might be selected as result.

The problem can be worked around by checking mem_cgroup_swappiness==0
and not considering swap at all in such a case.

ALSA: hda - Workaround for silent output on VAIO Z with ALC889

2012-10-02T17:29:53+00:00

commit e427c2375646789ecd0ccaef1a1e41458559ab2d upstream.

On recent kernels, Realtek codec parser tries to optimize the routing
aggressively and take the headphone output as primary at first.  This
caused a regression on VAIO Z with ALC889, the silent output from the
speaker.

The problem seems that the speaker pin must be connected to the first
DAC (0x02) on this machine by some reason although the codec itself
advertises the flexible routing with any DACs.

This patch adds a fix-up for choosing the speaker pin as the primary
so that the right DAC is assigned on this device.

commit 108cc108a3bb42fe4705df1317ff98e1e29428a6 upstream.

Also add a model/fixup string "lenovo-dock", so that other Thinkpad
users will be able to test this fixup easily, to see if it enables
dock I/O for them as well.

stable: Allow merging of backports for serious user-visible performance issues

2012-07-16T16:04:08+00:00

commit eb3979f64d25120d60b9e761a4c58f70b1a02f86 upstream.

Distribution kernel maintainers routinely backport fixes for users that
were deemed important but not "something critical" as defined by the
rules. To users of these kernels they are very serious and failing to fix
them reduces the value of -stable.

The problem is that the patches fixing these issues are often subtle and
prone to regressions in other ways and need greater care and attention.
To combat this, these "serious" backports should have a higher barrier
to entry.

This patch relaxes the rules to allow a distribution maintainer to merge
to -stable a backported patch or small series that fixes a "serious"
user-visible performance issue. They should include additional information on
the user-visible bug affected and a link to the bugzilla entry if available.
The same rules about the patch being already in mainline still apply.
