[PATCH] Revert "pata_atiixp: add SB700 PCI ID"

2007-08-28T10:14:55+00:00

That update broke build of pata_atiixp as it requires some PCI IDs
and other updates which have not been merged. Better remove it
from 2.6.20.

This reverts commit f327bcd16db3128a6c1885e03109361e167d1a56.

[PATCH] CPUFREQ: ondemand: add a check to avoid negative load calculation

2007-08-25T15:24:21+00:00

Due to rounding and inexact jiffy accounting, idle_ticks can sometimes
be higher than total_ticks. Make sure those cases are handled as
zero load case.

[PATCH] CPUFREQ: ondemand: fix tickless accounting and software coordination bug

2007-08-25T15:24:21+00:00

With tickless kernel and software coordination os P-states, ondemand
can look at wrong idle statistics. This can happen when ondemand sampling
is happening on CPU 0 and due to software coordination sampling also looks at
utilization of CPU 1. If CPU 1 is in tickless state at that moment, its idle
statistics will not be uptodate and CPU 0 thinks CPU 1 is idle for less
amount of time than it actually is.

This can be resolved by looking at all the busy times of CPUs, which is
accurate, even with tickless, and use that to determine idle time in a
round about way (total time - busy time).

Thanks to Arjan for originally reporting the ondemand bug on
Lenovo T61.

[PATCH] stifb: detect cards in double buffer mode more reliably

2007-08-25T15:24:20+00:00

Visualize-EG, Graffiti and A4450A graphics cards on PARISC can
be configured in double-buffer and standard mode, but the stifb
driver supports standard mode only.
This patch detects double-buffered cards more reliable.

It is a real bugfix for a very nasty problem for all parisc users which have
wrongly configured their graphic card.  The problem: The stifb graphics driver
will not detect that the card is wrongly configured and then nevertheless just
enables the graphics mode, which it shouldn't.  In the end, the user will see
no further updates / boot messages on the screen.

We had documented this problem already on our FAQ
(http://parisc-linux.org/faq/index.html#viseg "Why do I get corrupted graphics
with my Vis-EG/Graffiti/A4450A card?") but people still run into this problem.
 So having this fix in as early as possible can help us.

[PATCH] random: fix bound check ordering (CVE-2007-3105)

2007-08-25T15:24:18+00:00

If root raised the default wakeup threshold over the size of the
output pool, the pool transfer function could overflow the stack with
RNG bytes, causing a DoS or potential privilege escalation.

[PATCH] dm: disable barriers

2007-08-25T15:24:15+00:00

This patch causes device-mapper to reject any barrier requests.  This is done
since most of the targets won't handle this correctly anyway.  So until the
situation improves it is better to reject these requests at the first place.
Since barrier requests won't get to the targets, the checks there can be
removed.

[PATCH] dm snapshot: permit invalid activation

2007-08-25T15:24:15+00:00

Allow invalid snapshots to be activated instead of failing.

This allows userspace to reinstate any given snapshot state - for
example after an unscheduled reboot - and clean up the invalid snapshot
at its leisure.
