[PATCH 2/2][RFC] tracing: Add extract out softirq names used by irq trace events
The irq trace events that map the softirq vectors to strings shows up in the format files as names. To allow binary parsers to be able to convert these names to their actual numbers, this patch extracts those enums.

[PATCH] adcxx: Fix for single-channel ADCs
Hi, While testing a ADC121S021 in an embedded board with a S3C2142 SoC (ARM core), I have found that the 'adcxx' driver does not handle correctly single channel ADCs from this chip family. For single channel chips you must only issue one read transfer for correct measurement. Regards, Jos� Gon�alves ... 12 Feb 2010 10:02

Emulates PWM hardware using a high-resolution timer and a GPIO pin
2010/2/12 Stanislav O. Bezzubtsev <stas(a)lvk.cs.msu.su>: The second strange thing is "unsigned long <name>:1". I'm not sure but as far as I can remember the right way to define several-bits field is "int <name>:1". But I might be mistaken. A bitfield of size 1 should not be signed, as there's no space for a sign b... 12 Feb 2010 08:55

[PATCH 11/12] mm: Take the RCU read lock in rmap_walk_anon
rmap_walk_anon() does not use page_lock_anon_vma() for looking up and locking an anon_vma. One important difference between page_lock_anon_vma() and rmap_walk_anon() is that the page_lock_anon_vma() takes the RCU lock before the lookup so that the anon_vma does not disappear. There does not appear to be locking in ... 12 Feb 2010 07:50

[PATCH 10/12] mm: Check for an empty VMA list in rmap_walk_anon
There appears to be a race in rmap_walk_anon() that can be triggered by using page migration under heavy load on pages that do not belong to the process doing the migration - e.g. during memory compaction. The bug triggered is a NULL pointer deference in list_for_each_entry(). I believe what is happening is that ... 12 Feb 2010 07:50
