Given those two choices :
#if defined(CONFIG_SMP) || defined(CONFIG_PROVE__LOCKING)
kmalloc(sizeof(rwlock_t) * size);
#endif
and
if (sizeof(rwlock_t) != 0) {
kmalloc(sizeof(rwlock_t) * size);
}
I prefer the 2nd one. Less error prone, and no need to remember how are
spelled the gazillions CONFIG_something we have.

And similarly on SPARC64 is will be set based upon the
physical capabilities of the system.
This makes a huge different as we have to set NR_CPUS to 4096
in order to handle the cpu numbering of some UltraSPARC-IV

Add PHY IDs for Marvell 88E1240. It seems to have close enough programming

Also clean up whitespace in the ID list a bit.

Really? Hopefully you have a large enough stack then. There
are various users who put char str[NR_CPUS] on the stack
and a few other data structures also get incredibly big with
NR_CPUS arrays.
If it's for sparse cpu ids -- x86 handles those with an
translation array.

I thinking you were close. I am afraid my brain is congested, even the

It could be done with just fshift on the slow path (config time) of one

From: Rumen G. Bogdanovski <rumen@voicecho.com>
This patch makes the master daemon to sync the connection when it is about
to close. This makes the connections on the backup to close or timeout
according their state. Before the sync was performed only if the
connection is in ESTABLISHED state which always made the connections to
timeout in the hard coded 3 minutes. However the Andy Gospodarek's patch
([IPVS]: use proper timeout instead of fixed value) effectively did nothing
more than increasing this to 15 minutes (Established state timeout). So
this patch makes use of proper timeout since it syncs the connections on
status changes to FIN_WAIT (2min timeout) and CLOSE (10sec timeout).
However if the backup misses CLOSE hopefully it did not miss FIN_WAIT.
Otherwise we will just have to wait for the ESTABLISHED state timeout. As
it is without this patch. This way the number of the hanging connections
on the backup is kept to minimum. And very few of them will be left to
timeout with a long timeout.
This is important if we want to make use of the fix for the real server
overcommit on master/backup fail-over.

Rumen Bogdanovski

Two related patches from Rumen G. Bogdanovski
to help prevent overcommit on the standby.
On the last two attempts I have managed to send somewhat bogus patches.
So I started from scratch. I tool the original patches, fixed
up what scripts/checkpatch.pl didn't like, then compared the output
to my previous attempt, which happily showed the bogus bits
that I know about have been fixed.

This patch fixes the problem with node overload on director fail-over.
Given the scenario: 2 nodes each accepting 3 connections at a time and 2
directors, director failover occurs when the nodes are fully loaded (6
connections to the cluster) in this case the new director will assign
another 6 connections to the cluster, If the same real servers exist
there.
The problem turned to be in not binding the inherited connections to
the real servers (destinations) on the backup director. Therefore:
"ipvsadm -l" reports 0 connections:
root@test2:~# ipvsadm -l
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP test2.local:5999 wlc
-> node473.local:5999 Route 1000 0 0
-> node484.local:5999 Route 1000 0 0
while "ipvs -lnc" is right
root@test2:~# ipvsadm -lnc
IPVS connection entries
pro expire state source virtual destination
TCP 14:56 ESTABLISHED 192.168.0.10:39164 192.168.0.222:5999
192.168.0.51:5999
TCP 14:59 ESTABLISHED 192.168.0.10:39165 192.168.0.222:5999
192.168.0.52:5999
So the patch I am sending fixes the problem by binding the received
connections to the appropriate service on the backup director, if it
exists, else the connection will be handled the old way. So if the
master and the backup directors are synchronized in terms of real
services there will be no problem with server over-committing since
new connections will not be created on the nonexistent real services
on the backup. However if the service is created later on the backup,
the binding will be performed when the next connection update is
received. With this patch the inherited connections will show as
inactive on the backup:
root@test2:~# ipvsadm -l

Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn

For the stack case there is one debugging case, and that's for

I would rather not do this, so much assembler code indexes straight
into the per-cpu arrays.

Also, at current rates, I'll need to be able to support

Seems not good or I miss something:
host order:
address: xx.xx.xf.fx
hmask : 00.00.0f.f0
net order:
address: fx.xf.xx.xx
hmask : f0.0f.00.00
fshift after ntohl(s->hmask): 4
so, above:
h = (fx.xf.xx.xx & f0.0f.00.00) >> 4;
h == 0f.00.f0.00
return 00.f0.00.0f (?)
But, I hope, maybe Radu could check this better - after his analyze
it looks like his coffee is the best!
Currently I think this should be possible to get this one important
byte with 2 shifts, but it needs much more coffee on my slow path...
But, this wouldn't be very readable and I'm not sure the gain would
be really visible with current cpus, so maybe this first proposal is
quite reasonable. Then, I'd only suggest to Radu to change the '*'
style a bit in the comment and to sign this off, if you agree?
Cheers,
Jarek P.
BTW: when looking around this I think, maybe, in u32_change():
1) if (--divisor > 0x100) should be probably ">=", but is it really
needed to check this 2 times (including tc)?
2) this while() loop for n->fshift could be replaced with ffs()?

So how exactly do you want me to handle this (I'm still new to this device
tree stuff, so please bear with me)? Like this?
RGMII0: emac-rgmii@ef601000 {
device_type = "rgmii-interface";
compatible = "ibm,rgmii-405ex", "ibm,rgmii";
reg = <ef601000 8>;
has-mdio;
};
Or add this to the compatible property?
RGMII0: emac-rgmii@ef601000 {
device_type = "rgmii-interface";
compatible = "ibm,rgmii-405ex", "ibm,rgmii", "ibm,has-mdio";
reg = <ef601000 8>;
};

It's not only the OC bit-flip on AXON, but also the different STACR register
layout for read/write op-codes (STAOPC). This seems to be the same on all new
EMAC core's like on AXON, 440EPx/GRx and 405EX. So "stacr-oc-inverted" is not
enough here. This is what is needed for 440SPe, which "only" has the bit-flip
and the "old" STAOPC layout.
So perhaps most flexible would be to add individual properties,
like "stacr-oc-inverted" and "stacr-staopc-19-20". What do you think? And
again the additional question: Should the be added as an new property or
added to the compatible property?
Please advise. Thanks.
Best regards,
Stefan

This was fixed after the changeset you quoted so if you update

The above.
Properties without values are typically used for such "flags". I'll
fixup the driver to also take that for the inverted STACR and will post
a patch fixing that up asap.

Ok.

That's always the main question imho ... When it gets nasty like that I
tend to think the compatible property is a good compromise. It's mostly
a matter of taste. Unless you can come up with some more pleasant way to
do it... maybe a stacr-type property with multiple values but it's
really not worth complicating things when a compatible property will do
the job just fine. In that case, it's not really a "feature" of a given
implementation, but more about subtle differences between
implementations.

OK, thanks. I'll wait with further 405ex emac patches until you changed this
in the driver.

Maybe some extra information might help
This is what happens in the kernel while the command 'ip' is stucked in user level.

In this instance the rcu_dereference conversion doesn't make much
sense so we should probably just revert it.
