Add @print_info argument to ata_dev_configure(). Details of
configured device is printed only when @pinfo_info is non-zero. This
patch also reorganizes device info printing for LBA case to simplify
code (necessary as @print_info adds extra nesting around it).

In ata_dev_configure(), reinitialize parameters before configuring.
This change is for revalidation and hotplug. As ata_dev_configure()
can be entered multiple times, parameters need to be reinitialized.

This patch adds proper logic to cpufreq driver in order to handle
CPU Hotplug.
When CPUs go on/offline, the affected CPUs data, cpufreq_policy->cpus,
is not updated properly. This causes sysfs directories and symlinks to
be in an incorrect state after few CPU on/offlines.

powernow-k8: Let cpufreq driver handle affected CPUs
Let the cpufreq driver manage AMD Dual-Core CPUs being tied together.
Since cpufreq driver's affected CPUs data, cpufreq_policy->cpus, already
knows about which cores are tied together, powernow driver does not have
keep its internal data for every core. (even a pointer.. it will never
be called on) Telling cpufreq driver about cpu_core_map at init time is
sufficient.

session when multiply mounted.
Fixes slow response when cifs client is mounted to shares on multiple
servers and oplock break occurs (usually due to attempt to multiply open a
file). When treeids on mutiple mounted shares match and we find the wrong
match first, we searched for the wrong cached files to send oplock break
response for which usually meant that no matching file was found and thus
the server would have to timeout the notification. Oplock break timeout is
about 20 seconds on some servers so this could cause significantly slower
performance on file open calls in a few cases (in particular when multiple
shares are mounted from multiple servers, tree ids match, and we have a
cached file which is later opened multiple times). This was the most
important of the bugs that was found and fixed at Connectathon
(interoperability testing event) this week.

[MMC] au1xmmc: Fix a compilation warning ('status' is not used)
[MMC] au1xmmc: Fix linking error because mmc_rsp_type doesn't exist
[MMC] au1xmmc: Fix compilation error by using platform_driver
Building an allmodconfig kernel for ppc64 revealed a number of false
positives - originally reported by Andrew Morton.
This patch removes most if not all false positives for ppc64:
Section .opd
The .opd section contains function descriptors at least for ppc64.
So ignore it for .init.text (was ignored for .exit.text).
See description of function descriptors here:
http://www.linuxbase.org/spec/ELF/ppc64/PPC-elf64abi-1.7.html
Section .toc1
ppc64 places some static variables in .toc1 - ignore the.
Section __bug_tabe
BUG() and friends uses __bug_table. Ignore warnings from that section.
Module parameters are placed in .data.rel for ppc64, for adjust pattern to
match on section named .data*
Tested with gcc: 3.4.0 and binutils 2.15.90.0.3

As documented in National application note 1287 the RX state machine on
the natsemi chip can lock up under some conditions (mostly related to
heavy load). When this happens a series of bogus packets are reported
by the chip including some oversized frames prior to the final lockup.
This patch implements the fix from the application note: when an
oversized packet is reported it resets the RX state machine, dropping
any currently pending packets.

This patch converts the natsemi driver to use NAPI. It was originally

any more.

switch. In this patch, new flags are added in priv_flags of net_device
structure to let the bonding driver discard duplicate packets in
dev.c:skb_bond().
Modified by Jay Vosburgh to change a define name, update some

priv_flags on slave release, and update the driver version.

The function now does not disable device on failure, it just returns

configure and disabling devices according to the results, this patch
also kills ata_dev_identify() and inlines the logic into

Reimplement piix_sata_probe() such that it turns on PCS enable bits on
all avaliable ports and check present bits after a while to determine
device presence. This should help broken BIOSes. After device
presence detection is complete, PCS enable bits of unoccupied bits are
turned off unless the controller supports AHCI (ICH6/7 docs mandate
all enables bits are always set on AHCI capable controllers).
Note that PCS present bits are ignored on 6300ESB as described in the
datasheet. This should fix device detection problems reported with
the controller.
