With cmwq, there's no reason to use a separate workqueue in
cpufreq_spudemand. Use system_wq instead. The work items are already
sync canceled on stop, so it's already guaranteed that no work is

powerpc: Ensure the else case of feature sections will fit
When we create an alternative feature section, the else case must be the
same size or smaller than the body. This is because when we patch the
else case in we just overwrite the body, so there must be room.
Up to now we just did this by inspection, but it's quite easy to enforce
it in the assembler, so we should.
The only change is to add the ifgt block, but that effects the alignment
of the tabs and so the whole macro is modified.
Also add a test, but #if 0 it because we don't want to break the build.
Anyone who's modifying the feature macros should enable the test.

ns83820: Avoid bad pointer deref in ns83820_init_one().
In drivers/net/ns83820.c::ns83820_init_one() we dynamically allocate
memory via alloc_etherdev(). We then call PRIV() on the returned storage
which is 'return netdev_priv()'. netdev_priv() takes the pointer it is
passed and adds 'ALIGN(sizeof(struct net_device), NETDEV_ALIGN)' to it and
returns it. Then we test the resulting pointer for NULL, which it is
unlikely to be at this point, and later dereference it. This will go bad
if alloc_etherdev() actually returned NULL.

ipv6: Silence privacy extensions initialization
When a network namespace is created (via CLONE_NEWNET), the loopback
interface is automatically added to the new namespace, triggering a
printk in ipv6_add_dev() if CONFIG_IPV6_PRIVACY is set.
This is problematic for applications which use CLONE_NEWNET as
part of a sandbox, like Chromium's suid sandbox or recent versions of
vsftpd. On a busy machine, it can lead to thousands of useless
"lo: Disabled Privacy Extensions" messages appearing in dmesg.
It's easy enough to check the status of privacy extensions via the
use_tempaddr sysctl, so just removing the printk seems like the most
sensible solution.

iwlwifi: fix valid chain reading from EEPROM
When read valid tx/rx chains from EEPROM, there is a bug to use the
tx chain value for both tx and rx, the result of this cause low
receive throughput on 1x2 devices becuase rx will only utilize single
chain instead of two chains

perf: Validate cpu early in perf_event_alloc()
Starting from perf_event_alloc()->perf_init_event(), the kernel
assumes that event->cpu is either -1 or the valid CPU number.
Change perf_event_alloc() to validate this argument early. This
also means we can remove the similar check in
find_get_context().

While most users of a physical Malta board are using the serial port

perf: Fix contexted inheritance
Linus reported that the RCU lockdep annotation bits triggered for this
rcu_dereference() because we're not holding rcu_read_lock().
Going over the code I cannot convince myself its correct:
- holding a ref on the parent_ctx, doesn't avoid it being uncloned
concurrently (as the comment says), so we can race with a free.
- holding parent_ctx->mutex doesn't avoid the above free from taking
place either, it would at best avoid parent_ctx from being freed.
I.e. the warning is correct. To fix the bug, serialize against the
unclone_ctx() call by extending the reach of the parent_ctx->lock.

x86: Make relocatable kernel work with new binutils
The CONFIG_RELOCATABLE=y option is broken with new binutils, which will make
boot panic.
According to Lu Hongjiu, the affected binutils are from 2.20.51.0.12 to
2.21.51.0.3, which are release since Oct 22 this year. At least ubuntu 10.10 is
using such binutils. See:
http://sourceware.org/bugzilla/show_bug.cgi?id=12327
The reason of the boot panic is that we have 'jiffies = jiffies_64;' in
vmlinux.lds.S. The jiffies isn't in any section. In kernel build, there is
warning saying jiffies is an absolute address and can't be relocatable. At
runtime, jiffies will have virtual address 0.

Further down, at the current dentry check for it being simple_positive()

ret, otherwise when p is assinged to ret we end up with no lock on p and
a lost lock on ret, which leads to a deadlock.
