Consolidates validation of scope and name sequence range values into
a single routine where it applies both to local name publications
and to name publications issued by other nodes in the network. This
change means that the scope value for non-local publications is now
validated and the name sequence range for local publications is now
validated only once. Additionally, a publication attempt that fails
validation now creates an entry in the system log file only if debugging
capabilities have been enabled; this prevents the system log from being
cluttered up with messages caused by a defective application or network
node.

Streamlines the job of re-initializing TIPC's network topology service
when a node's network address is first assigned. Rather than destroying
the topology server port and breaking its connections to existing
subscribers, TIPC now simply lets the service continue running (since
the change to the port identifier of each port used by the topology
service no longer impacts the flow of messages between the service and
its subscribers).
This enhancement means that applications that utilize the topology
service prior to the assignment of TIPC's network address no longer need
to re-establish their subscriptions when the address is finally assigned.
However, it is worth noting that any subsequent events for existing
subscriptions report the new port identifier of the publishing port,
rather than the original port identifier. (For example, a name that was
previously reported as being published by <0.0.0:ref> may be subsequently
withdrawn by <Z.C.N:ref>.)
This doesn't impact any of the existing known userspace in tipc-utils,
since (a) TIPC continues to treat references to the original port ID
correctly and (b) normal use cases assign an address before active use.
However if there does happen to be some rare/custom application out
there that was relying on this, they can simply bypass the enhancement
by issuing a subscription to {0,0} and break its connection to the
topology service, if an associated withdrawal event occurs.

In pirq_check_eoi_map use the pirq number rather than the Linux irq
number to check whether an eoi is needed in the pirq_eoi_map.
The reason is that the irq number is not always identical to the
pirq number so if we wrongly use the irq number to check the
pirq_eoi_map we are going to check for the wrong pirq to EOI.
As a consequence some interrupts might not be EOI'ed by the

There are exactly four users of __monitor and __mwait:
- cstate.c (which allows acpi_processor_ffh_cstate_enter to be called
when the cpuidle API drivers are used. However patch
"cpuidle: replace xen access to x86 pm_idle and default_idle"
provides a mechanism to disable the cpuidle and use safe_halt.
- smpboot (which allows mwait_play_dead to be called). However
safe_halt is always used so we skip that.
- intel_idle (same deal as above).
- acpi_pad.c. This the one that we do not want to run as we
will hit the below crash.
Why do we want to expose MWAIT_LEAF in the first place?
We want it for the xen-acpi-processor driver - which uploads
C-states to the hypervisor. If MWAIT_LEAF is set, the cstate.c
sets the proper address in the C-states so that the hypervisor
can benefit from using the MWAIT functionality. And that is
the sole reason for using it.
Without this patch, if a module performs mwait or monitor we
get this:

This file has lots and lots of ifdef, around structure decls
and structure usages. The failure issue was that we would
build the BF538-EZKIT_defconfig and get:
arch/blackfin/mach-bf538/boards/ezkit.c:924:3: error: 'bfin_lq035q1_device'
undeclared here (not in a function)
even though the same ifdef _appeared_ to enable both the struct
declaration and the code that used it. Yet cpp was telling us we
didn't have the struct, but we still had the usage of it.
However, _appeared_ is the operative word. After marking all the
anonymous #endif with their parent #ifdef config options, it was
_then_ clear that there was a misplaced #endif that was hiding
the struct declaration.
The real guts of the patch boils down to this:
-#endif
+#endif /* CONFIG_MTD_M25P80 */
+#endif /* CONFIG_SPI_BFIN5XX */
[...]
-#endif /* spi master and devices */
but since I had to tag the #endif with their respective #ifdef
options to find this misplaced SPI endif, it would be silly to
then go and delete them all. So they stay.

We seem to have a decent confusion between the output timings and the
input timings of the sdvo encoder. If I understand the code correctly,
we use the original mode unchanged for the output timings, safe for
the lvds case. And we should use the adjusted mode for input timings.
Clarify the situation by adding an explicit output_dtd to the sdvo
mode_set function and streamline the code-flow by moving the input and
output mode setting in the sdvo encode together.
Furthermore testing showed that the sdvo input timing needs the
unadjusted dotclock, the sdvo chip will automatically compute the
required pixel multiplier to get a dotclock above 100 MHz.
Fix this up when converting a drm mode to an sdvo dtd.
This regression was introduced in

/* If it's a TV, we already set the output timing in mode_fixup.
* Otherwise, the output timing is equal to the input timing.
Due to questions raised in review, below a more elaborate analysis of
the bug at hand:
Sdvo seems to have two timings, one is the output timing which will be
sent over whatever is connected on the other side of the sdvo chip (panel,
hdmi screen, tv), the other is the input timing which will be generated by
the gmch pipe. It looks like sdvo is expected to scale between the two.
To make things slightly more complicated, we have a bunch of special
cases:
- For lvds panel we always use a fixed output timing, namely
intel_sdvo->sdvo_lvds_fixed_mode, hence that special case.
- Sdvo has an interface to generate a preferred input timing for a given
output timing. This is the confusing thing that I've tried to clear up
with the follow-on patches.
- A special requirement is that the input pixel clock needs to be between
100MHz and 200MHz (likely to keep it within the electromechanical design
range of PCIe), 270MHz on later gen4+. Lower pixel clocks are
doubled/quadrupled.
The thing this patch tries to fix is that the pipe needs to be
explicitly instructed to double/quadruple the pixels and needs the
correspondingly higher pixel clock, whereas the sdvo adaptor seems to
do that itself and needs the unadjusted pixel clock. For the sdvo
encode side we already set the pixel mutliplier with a different
command (0x21).
This patch tries to fix this mess by:
- Keeping the output mode timing in the unadjusted plain mode, safe
for the lvds case.
- Storing the input timing in the adjusted_mode with the adjusted
pixel clock. This way we don't need to frob around with the core
crtc mode set code.
- Fixing up the pixelclock when constructing the sdvo dtd timing
struct. This is why the first hunk of the patch is an integral part
of the series.
- Dropping the is_tv special case because input_dtd is equivalent to
adjusted_mode after these changes. Follow-up patches clear this up
further (by simply ripping out intel_sdvo->input_dtd because it's
not needed).

iterate over the siblings of the event.
However we don't call the function on the siblings, we call it
repeatedly on the original event - it seems "obvious" that we should
be calling it with sibling as the argument.
It looks like this broke in commit 75f937f24b ("Fix ctx->mutex

By setting loop_max unconditionally to ->nr_running load-balancing
could take a lot of time on very long runqueues (hackbench!). So keep
the sysctl as max limit of the amount of tasks we'll iterate.
Furthermore, the min load filter for migration completely fails with
cgroups since inequality in per-cpu state can easily lead to such
small loads :/
Furthermore the change to add new tasks to the tail of the queue
instead of the head seems to have some effect.. not quite sure I

Combined these fixes solve the huge hackbench regression reported by

The dl2k driver's rio_ioctl call has a few issues:
- No permissions checking
- Implements SIOCGMIIREG and SIOCGMIIREG using the SIOCDEVPRIVATE numbers
- Has a few ioctls that may have been used for debugging at one point
but have no place in the kernel proper.
This patch removes all but the MII ioctls, renumbers them to use the
standard ones, and adds the proper permission check for SIOCSMIIREG.
We can also get rid of the dl2k-specific struct mii_data in favor of
the generic struct mii_ioctl_data.
Since we have the phyid on hand, we can add the SIOCGMIIPHY ioctl too.
Most of the MII code for the driver could probably be converted to use
the generic MII library but I don't have a device to test the results.

multicast packets and ignores the MAC parameter, just what allmulticast
needs. The normals filters, however, should not use SCOPE_ALL.

merge TXQ/RXQ/MAC start/enable code to one function as they
are started/enabled at the same time, just like stop/disable them
in the function of atl1c_stop_mac.

This function is used for suspend of S1/S3/S4 and driver remove.
It sets MAC/PHY based on the WoL configuation to get lower power
consumption.
atl1c_phy_power_saving is renamed to atl1c_phy_to_ps_link, this
function is just make PHY enter a link/speed mode to eat less
power.
REG_MAC_CTRL register is refined as well.

it's unnecessary to reset/init phy when link down.
Only L1/L2 chip (supported by atlx) need such action.

Many magic data are re-configured for PHY during its reset operation
based on chip type to get better compability and stability.
REG_PHY_CTRL register may be configured by BIOS before enter OS.
so, the driver can't directly write to it without any Read-Op.
this change also affect suspend and phy_disable routines.
PHY debug ports and extension registers are refined as well.

bit 17/18 of reg1424 must be clear for l2cb 1.x, or it will cause
the write-reg operation fail without cable connected.
so, please do connect the cable when apply this patch to the driver
to make sure these 2bits are cleared by new driver.
The revised code is move to al1c_reset_mac.
SERDES register definition is refined as well.
when do reset MAC, speed/duplex control right should be transferred
to software before do PHY auto-neg -- by bit MASTER_CTRL_SPEED_MODE_SW.
SERDES register definition is refined as well.

atl1c_reset_phy follows atl1c_reset_pcie in the whole driver,
so, it's unnecessary to add PHY control code in atl1c_reset_pcie.

phy register is read/write via MDIO control module ---
that module will be affected by the hibernate status,
to access phy regs in hib stutus, slow frequency clk must
be selected.
To access phy extension register, the MDIO related
registers are refined/updated, a _core function is
re-wroted for both regular PHY regs and extension regs.
existing PHY r/w function is revised based on the _core.
PHY extension registers will be used for the comming
patches.
