As Richard Smith pointed out, ACR * 6250 / 15 provides for less
precision loss than ACR * 4167 / 10, _and_ it doesn't overflow. Switch
to using that equation for CHARGE_COUNTER.Signed-off-by: Andres Salomon

This adds PROP_CHARGE_COUNTER to the power supply class (documenting it
as well). The OLPC battery driver uses this for spitting out its ACR
values (in uAh). We have some rounding errors (the data sheet claims
416.7, the math actually works out to 416.666667, so we're forced to
choose between overflows or precision loss. I chose precision loss,
and stuck w/ data sheet values), but I don't think anyone will care
that much.Signed-off-by: Andres Salomon

This allows you to dump 0x60 bytes from the battery's EEPROM (starting at
address 0x20). Note that it does an EC command for each byte, so it's pretty
slow. OTOH, if you want to grab just a single byte from somewhere in the
EEPROM, you can do something like:dd bs=1 count=1 skip=16 if=/sys/class/power_supply/olpc-battery/eeprom | od -x
Userspace battery collection/logging information needs this.

This replaces the duplicated arch-specific versions of "sys_pipe()" with
one unified implementation. This removes almost 250 lines of duplicated
code.It's marked __weak, so that *if* an architecture wants to override the
default implementation it can do so by simply having its own replacement
version, since many architectures use alternate calling conventions for
the 'pipe()' system call for legacy reasons (ie traditional UNIX
implementations often return the two file descriptors in registers)I still haven't changed the cris version even though Linus says the BKL
isn't needed. The arch maintainer can easily do it if there are really
no obstacles.Signed-off-by: Ulrich Drepper

Signed-off-by: David S. Miller -
When a netdev is moved across namespaces with the
'dev_change_net_namespace' function, the 'device_rename' function is
used to fixup kobject and refresh the sysfs tree. The device_rename
function will call kobject_rename and this one will check if there is
an object with the same name and this is the case because we are
renaming the object with the same name.The use of 'device_rename' seems for me wrong because we usually don't
rename it but just move it across namespaces. As we just want to do a
mini "netdev_[un]register", IMO the functions
'netdev_[un]register_kobject' should be used instead, like an usual
network device [un]registering.This patch replace device_rename by netdev_unregister_kobject,
followed by netdev_register_kobject.The netdev_register_kobject will call device_initialize and will raise
a warning indicating the device was already initialized. In order to
fix that, I split the device initialization into a separate function
and use it together with 'netdev_register_kobject' into
register_netdevice. So we can safely call 'netdev_register_kobject' in
'dev_change_net_namespace'.This fix will allow to properly use the sysfs per namespace which is
coming from -mm tree.Signed-off-by: Daniel Lezcano

1. The jumbo rx buffer page size is now configurable and set to the

firmware DMA'ing to the wrong address.Signed-off-by: Michael Chan

On some remote PHY blade systems, the driver receives no initial link

The forwarding table binary interface (my bad choice), only exposes
the port number of the first 8 bits. The bridge code was limited to
256 ports at the time, but now the kernel supports up 1024 ports, so
the upper bits are lost when doing:brctl showmacs
The fix is to squeeze the extra bits into small hole left in data
structure, to maintain binary compatiablity.Signed-off-by: Stephen Hemminger

All variants of the 5714, 5715, and 5780 offer a feature called the
"Universal Management Port". This feature is implemented in firmware
and is largely transparent to the driver, except...It turns out that the UMP firmware needs to know the current status
of the link. Because the firmware cannot touch the PHY registers while
the driver is in control of the device, it needs the driver to report
link status changes through an additional handshaking mechanism.
Without this handshake, it has been observed in the field that the UMP
firmware will not operate correctly.This patch implements the new handshake with the UMP firmware. Since
the handshake uses the same mechanism ASF heartbeats use, code was
added to detect and wait for completion of a pending previous event.Signed-off-by: Matt Carlson

A CPMU related loopback test bug existed for AX revisions of the 5761.
While that errata has been fixed, the CPMU still slows down the core

The MI clock is not configured correctly on adapters with the CPMU
present. The tg3 driver has code which statically sets the MI clock to
be a fraction of the speed at which the core clock is running.
However, the CPMU can change the adapter's core clock frequency based
on operating conditions. Consequently, the MI will run slow when the
core's clock has been slowed down.There is a new 500KHz constant frequency clock available on adapters
with a CPMU. This patch removes the static core clock scaling and
configures the MI clock to use this new 500KHz clock instead.Running the MI clock at slower speeds will not directly result in data
corruption, but it does challenge the PHY read and write routine timeouts.Signed-off-by: Matt Carlson
