There's some odd bug in gcc-4.2 where it miscompiles a simple loop whent
he loop counter is of type 'unsigned char' and it should count to 128.
The compiler will incorrectly decide that a trivial loop like this:
unsigned char i, ...
for (i = 0; i < 128; i++) {
..
is endless, and will compile it to a single instruction that just
branches to itself.
This was triggered by the addition of '-fno-strict-overflow', and we
could play games with compiler versions and go back to '-fwrapv'
instead, but the trivial way to avoid it is to just make the loop
induction variable be an 'int' instead.
Thanks to Krzysztof Oledzki for reporting and testing and to Troy Moure
for digging through assembler differences and finding it.

I'm using ide on 2.6.30.1 with xfs filesystem. I noticed a kernel memory
leak after writing lots of data, the kmalloc-96 slab cache keeps
growing. It seems the struct ide_cmd kmalloced by idedisk_prepare_flush
is never kfreed.
Commit a09485df9c ("ide: move request
type specific code from ide_end_drive_cmd() to callers (v3)") and
f505d49ffd ("ide: fix barriers support")
cause this regression, cmd->rq must now be set for ide_complete_cmd to

via a vendor-specific USB interface. CDC Phonet follows the
Communications Device Class model, with one control interface, and
and a pair of inactive and active data alternative interface. The later
has two bulk endpoint, one per direction.
This was tested against Nokia E61, Nokia N95, and the existing Phonet

A pointer to mac_sonic_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.
Various other functions that are called by mac_sonic_probe need to move
to .devinit.text, too.
An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

Since 2.6.30 (commit 4995f8ef9d, 'vcs:

netxen: fix deadlock on dev close
The tx ring accounting fix in commit cb2107be43
("netxen: fix tx ring accounting") introduced intermittent

This was possibly combined effect of speculative tx pause,
calling netif_tx_lock instead of queue lock and unclean
synchronization with napi which could end up unmasking

The variable virtio_blk references the function virtblk_probe() (which
is in .devinit section) and also references the function
virtblk_remove() ( which is in .devexit section). So, virtio_blk
simultaneously refers .devinit and .devexit section. To avoid this
messup, we mark virtio_blk as __refdata.
