Add infrastructure to track "maximum allowable latency" for power saving
policies.
The reason for adding this infrastructure is that power management in the
idle loop needs to make a tradeoff between latency and power savings
(deeper power save modes have a longer latency to running code again). The
code that today makes this tradeoff just does a rather simple algorithm;
however this is not good enough: There are devices and use cases where a
lower latency is required than that the higher power saving states provide.
An example would be audio playback, but another example is the ipw2100
wireless driver that right now has a very direct and ugly acpi hook to
disable some higher power states randomly when it gets certain types of
error.
The proposed solution is to have an interface where drivers can
* announce the maximum latency (in microseconds) that they can deal with
* modify this latency
* give up their constraint
and a function where the code that decides on power saving strategy can
query the current global desired maximum.
This patch has a user of each side: on the consumer side, ACPI is patched
to use this, on the producer side the ipw2100 driver is patched.
A generic maximum latency is also registered of 2 timer ticks (more and you
lose accurate time tracking after all).
While the existing users of the patch are x86 specific, the infrastructure
is not. I'd like to ask the arch maintainers of other architectures if the
infrastructure is generic enough for their use (assuming the architecture
has such a tradeoff as concept at all), and the sound/multimedia driver
owners to look at the driver facing API to see if this is something they
can use.

MSI is defined to be 32-bit write. The 5706 does 64-bit MSI writes
with byte enables disabled on the unused 32-bit word. This is legal
but causes problems on the AMD 8132 which will eventually stop
responding after a while.
Without this patch, the MSI test done by the driver during open will
pass, but MSI will eventually stop working after a few MSIs are
written by the device.
AMD believes this incompatibility is unique to the 5706, and
prefers to locally disable MSI rather than globally disabling it
using pci_msi_quirk.

Introduce the disable_irq_nosync_lockdep_irqsave() and
enable_irq_lockdep_irqrestore() APIs. These are needed for NE2000; basically
NE2000 calls disable_irq and enable_irq as locking against the IRQ handler,
but both in cases where interrupts are on and off. This means that lockdep
needs to track the old state of the virtual irq flags on disable_irq, and
restore these at enable_irq time.

The purpose of this patch is to split off the case when a device does
not reply on the lower level (which is reported by HC hardware), and
a case when the device accepted the request, but does not reply at
upper level. This redefinition allows to diagnose issues easier,
without asking the user if the -110 happened "immediately".
The usbmon splits such cases already thanks to its timestamp, but
it's not always available.

Add modalias attribute support for the almost forgotten now EISA bus and
(at least some) EISA-aware modules.
The modalias entry looks like (for an 3c509 NIC):
eisa:sTCM5093
and the in-module alias like:
eisa:sTCM5093*
The patch moves struct eisa_device_id declaration from include/linux/eisa.h
to include/linux/mod_devicetable.h (so that the former now #includes the
latter), adds proper MODULE_DEVICE_TABLE(eisa, ...) statements for all
drivers with EISA IDs I found (some drivers already have that DEVICE_TABLE
declared), and adds recognision of __mod_eisa_device_table to
scripts/mod/file2alias.c so that proper modules.alias will be generated.
There's no support for /lib/modules/$kver/modules.eisamap, as it's not used
by any existing tools, and because with in-kernel modalias mechanism those
maps are obsolete anyway.
The rationale for this patch is:
a) to make EISA bus to act as other busses with modalias
support, to unify driver loading
b) to foget about EISA finally - with this patch, kernel
(who still supports EISA) will be the only one who knows
how to choose the necessary drivers for this bus ;)

(i.e., with no spinlock or other debugging functions enabled; if you want to
save memory taken up by in-core inodes, the first thing you should do is
disable the debugging options; they are responsible for a huge amount of bloat
in the VFS inode structure).
This patch:
The filesystem or device-specific pointer in the inode is inside a union,
which is pretty pointless given that all 30+ users of this field have been
using the void pointer. Get rid of the union and rename it to i_private, with
a comment to explain who is allowed to use the void pointer. This is just a
cleanup, but it allows us to reuse the union 'u' for something something where
the union will actually be used.

Add logic to check ARP request / reply packets used for ARP
monitor link integrity checking.
The current method simply examines the slave device to see if it
has sent and received traffic; this can be fooled by extraneous traffic.
For example, if multiple hosts running bonding are behind a common
switch, the probe traffic from the multiple instances of bonding will
update the tx/rx times on each other's slave devices.

When a bonding netdevice is admin-ed down it loses the slaves
attributes (set via ifenslave). This is not consistent with other
behavior of netdevices (example a qdisc attached to a netdevice doesnt
disappear or an attached IP address etc).
The included patch fixes this. Ive tested by ifenslaving, downing the
bond, checking /proc and making sure it still has the slaves, up-ing the
bond and making sure things continue to work.

Add priv_flag to specifically identify bonding-involved devices. Needed
because IFF_MASTER is an unreliable identifier (vlan interfaces above bonding

The bonding driver fails to adjust its hard_header_len when enslaving
interfaces. Whenever an interface with a hard_header_len greater than the
ETH_HLEN default is enslaved, the potential for an oops exists, and if the
oops happens while responding to an arp request, for example, the system
panics. GIANFAR devices may use an extended hard_header for VLAN or
hardware checksumming. Enslaving such a device and then transmitting over
it causes a kernel panic.

The fs_no mean used to be fs_enet driver driven, hence it was an

QE on the pipeline, and to make DTS descriptions more clear, fs_no features

Another reason for that is now not only fs_enet is going to utilize those
