Russell King [Wed, 29 Jun 2005 17:45:19 +0000]
[PATCH] Serial: Split 8250 port table (part 2)

Remove legacy ISA serial ports for Accent, Boca, Fourport, Hub6 and MCA
from the architecture specific serial.h include.

The only ports which remain in asm-*/serial.h are the platform specific
entries.  These should really be converted by platform maintainers to
use a platform device, such as can be found in
arch/arm/mach-footbridge/isa.c

[PATCH] Serial: Disable OX950 transmitter for flow control

Disable the transmitter whenever we want to prevent characters
being transmitted by flow control.  However, if we run out of
characters to send and want to only disable the TX interrupt,
allow that scenario.

although thats now fixed with the VIA quirk (which we could just make default
as its what Redmond OS does but Linus didn't like it historically).

A small number of systems have jammed IRQ sources or misdescribes that cause
an IRQ that we have no handler registered anywhere for.  In those cases it
doesn't help.

Mingming Cao [Wed, 29 Jun 2005 03:45:16 +0000]
[PATCH] ext3: reduce allocate-with-reservation lock latencies

Currently in ext3 block reservation code, the global filesystem reservation
tree lock (rsv_block) is hold during the process of searching for a space
to make a new reservation window, including while scaning the block bitmap
to verify if the avalible window has a free block.  Holding the lock during
bitmap scan is unnecessary and could possibly cause scalability issue and
latency issues.

This patch tries to address this by dropping the lock before scan the
bitmap.  Before that we need to reserve the open window in case someone
else is targetting at the same window.  Question was should we reserve the
whole free reservable space or just the window size we need.  Reserve the
whole free reservable space will possibly force other threads which
intended to do block allocation nearby move to another block group(cause
bad layout).  In this patch, we just reserve the desired size before drop
the lock and scan the block bitmap.  This patch fixed a ext3 reservation
latency issue seen on a cvs check out test.  Patch is tested with many fsx,
tiobench, dbench and untar a kernel test.

Also, split the function in 2.  A light version, current_io_context does not

context, because the process holds a reference itself.

[PATCH] blk: __make_request efficiency

In the case where the request is not able to be merged by the elevator, don't
retake the lock and retry the merge mechanism after allocating a new request.

Instead assume that the chance of a merge remains slim, and now that we've
done most of the work allocating a request we may as well just go with it.

Also be rid of the GFP_ATOMIC allocation: we've got working mempools for the
block layer now, so let's save atomic memory for things like networking.

Lastly, in get_request_wait, do an initial get_request call before going into
the waitqueue.  This is reported to help efficiency.

In the case of buffered AIO, in the aio retry path (aio_run_iocb), when the
retry method returns EIOCBRETRY the kicked iocb is added to the context run

never completed.

This patch fixes that by adding the appropriate call to aio_queue_work in

[PATCH] ITIMER_REAL: fix possible deadlock and race

As Steven Rostedt pointed out, there are 2 problems with ITIMER_REAL
timers.

1. do_setitimer() does not call del_timer_sync() in case
   when the timer is not pending (it_real_value() returns 0).
   This is wrong, the timer may still be running, and it can
   rearm itself.

2. It calls del_timer_sync() with tsk->sighand->siglock held.
   This is deadlockable, because timer's handler needs this
   lock too.

[IPVS]: Close race conditions on ip_vs_conn_tab list modification

In an smp system, it is possible for an connection timer to expire, calling
ip_vs_conn_expire while the connection table is being flushed, before
ct_write_lock_bh is acquired.

Since the list iterator loop in ip_vs_con_flush releases and re-acquires the
spinlock (even though it doesn't re-enable softirqs), it is possible for the
expiration function to modify the connection list, while it is being traversed
in ip_vs_conn_flush.

The result is that the next pointer gets set to NULL, and subsequently
dereferenced, resulting in an oops.

15 years ago[NET]: Remove gratuitous use of skb->tail in network drivers.
David S. Miller [Tue, 28 Jun 2005 22:25:31 +0000]
[NET]: Remove gratuitous use of skb->tail in network drivers.

Many drivers use skb->tail unnecessarily.

In these situations, the code roughly looks like:

dev = dev_alloc_skb(...);

[optional] skb_reserve(skb, ...);

... skb->tail ...

But even if the skb_reserve() happens, skb->data equals
skb->tail.  So it doesn't make any sense to use anything
other than skb->data in these cases.

Another case was the s2io.c driver directly mucking with
the skb->data and skb->tail pointers.  It really just wanted
to do an skb_reserve(), so that's what the code was changed
to do instead.

Another reason I'm making this change as it allows some SKB
cleanups I have planned simpler to merge.  In those cleanups,
skb->head, skb->tail, and skb->end pointers are removed, and
replaced with skb->head_room and skb->tail_room integers.

[PATCH] ll_rw_blk: prevent huge request allocations

Currently we cap request allocations at q->nr_requests, but we allow a
batching io context to allocate up to 32 more (default setting).  This
can flood the queue with request allocations, with only a few batching
processes.  The real fix would be to limit the number of batchers, but
as that isn't currently tracked, I suggest we just cap the maximum
number of allocated requests to eg 50% over the limit.

This was observed in real life, users typically see this as vmstat bo
numbers going off the wall with seconds of no queueing afterwards.
Behaviour this bursty is not beneficial.

[IPV4]: ipconfig.c: fix dhcp timeout behaviour

I think there is a small bug in ipconfig.c in case IPCONFIG_DHCP is set
and dhcp is used.

When a DHCPOFFER is received, ip address is kept until we get DHCPACK.
If no ack is received, ic_dynamic() returns negatively, but leaves the
offered ip address in ic_myaddr.

This makes the main loop in ip_auto_config() break and uses the maybe

David S. Miller [Thu, 2 Jun 2005 19:55:50 +0000]
[PATCH] PCI: DMA bursting advice

After seeing, at best, "guesses" as to the following kind
of information in several drivers, I decided that we really
need a way for platforms to specifically give advice in this
area for what works best with their PCI controller implementation.

Basically, this new interface gives DMA bursting advice on
PCI.  There are three forms of the advice:

1) Burst as much as possible, it is not necessary to end bursts
   on some particular boundary for best performance.

2) Burst on some byte count multiple.  A DMA burst to some multiple of
   number of bytes may be done, but it is important to end the burst
   on an exact multiple for best performance.

   The best example of this I am aware of are the PPC64 PCI
   controllers, where if you end a burst mid-cacheline then
   chip has to refetch the data and the IOMMU translations
   which hurts performance a lot.

3) Burst on a single byte count multiple.  Bursts shall end
   exactly on the next multiple boundary for best performance.

   Sparc64 and Alpha's PCI controllers operate this way.  They
   disconnect any device which tries to burst across a cacheline
   boundary.

   Actually, newer sparc64 PCI controllers do not have this behavior.
   That is why the "pdev" is passed into the interface, so I can
   add code later to check which PCI controller the system is using
   and give advice accordingly.

[PATCH] acpi bridge hotadd: Make pcibios_fixup_bus() hot-plug safe

PCI scan code calls the arch specific pcibios_fixup_bus() each time it scans a
new bridge.  For root bridge hot-plug, the bridge and it's attached devices
may not have been configured properly yet, so it's not safe to claim those
resources at this time.

This code goes away when we clean up the way pci resources are claimed (in
pci_enable_device()), so this is only a stopgap fix.

[PATCH] acpi bridge hotadd: Fix pci_enable_device() for p2p bridges

When checking if a PCI to PCI bridge should be enabled to decode memory and/or
IO resources, we need to look at all device resources not just the first 6.
This is needed to allow PCI bridges to pass down memory and IO accesses to
child devices even when the bridge itself does not consume resources in its
PCI BARs.

15 years ago[PATCH] acpi bridge hotadd: ACPI based root bridge hot-add
Rajesh Shah [Thu, 28 Apr 2005 07:25:45 +0000]
[PATCH] acpi bridge hotadd: ACPI based root bridge hot-add

When you hot-plug a (root) bridge hierarchy, it may have p2p bridges and
devices attached to it that have not been configured by firmware.  In this
case, we need to configure the devices before starting them.  This patch
separates device start from device scan so that we can introduce the
configuration step in the middle.

I kept the existing semantics for pci_scan_bus() since there are a huge number
of callers to that function.

Also, I have no way of testing the changes I made to the parisc files, so this
needs review by those folks.  Sorry for the massive cross-post, this touches
files in many different places.
