2005-06-27[PATCH] acpi bridge hotadd: Link newly created pci child bus to its parent ↵Rajesh Shah
on creation When a pci child bus is created, add it to the parent's children list immediately rather than waiting till pci_bus_add_devices(). For hot-plug bridges/devices, pci_bus_add_devices() may be called much later, after they have been properly configured. In the meantime, this allows us to use the normal pci bus search functions for the hot-plug bridges/buses.

2005-06-27[PATCH] acpi bridge hotadd: Prevent duplicate bus numbers when scanning PCI ↵Rajesh Shah
bridge When hot-plugging a root bridge, as we try to assign bus numbers we may find that the hotplugged hieratchy has more PCI to PCI bridges (i.e. bus requirements) than available. Make sure we don't step over an existing bus when that happens.

2005-06-27[PATCH] acpi bridge hotadd: ACPI based root bridge hot-addRajesh Shah
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.

2005-06-26[PATCH] defxx: Use irqreturn_t for the interrupt handlerMaciej W. Rozycki
This is a fix for the interrupt handler in the defxx driver to use irqreturn_t. Beside the obvious fix of returning a proper status at all, it actually checks board registers as appropriate for determining if an interrupt has been recorded in the bus-specific interface logic. The patch also includes an obvious one-line fix for SET_NETDEV_DEV needed for the EISA variation, for which I've decided there is no point in sending separately. Signed-off-by: Maciej W.

2005-06-26[PATCH] pcnet_cs.c: IRQ handler optimizationAndreas Mohr
During some performance diagnostics I stumbled on this slightly wasteful code in pcnet_cs.c which I made the patch included at the bottom for (two minor comment fixes included). Improvement: instead of *always* calculating lea 0x2c0(%edx),%ebx and then additionally doing the mov %edx,0xc0(%ebx) addition *if we need it*, we now do the *whole* calculation of mov %edx,0x380(%ebx) *only* if we need it. This even manages to save us a whole 16-byte alignment buffer loss in this compilation case. Result: slightly improves IRQ handler performance in both shared and non-shared IRQ case, which should make my rusty P3/700 a slight bit happier.

2005-06-268139cp: safer spin loop for get_statisticsStephen Hemminger
The spin loop in 8139cp is limited to 100 iterations when pulling hardware stats. There is no allowance for processor speed so on a fast machine, the stats may not be available that fast. Also, if the board doesn't return soon enough make sure turn the address back off to prevent later updates when memory has gone away.

2005-06-26bonding: xor/802.3ad improved slave hashJay Vosburgh
Add support for alternate slave selection algorithms to bonding balance-xor and 802.3ad modes. Default mode (what we have now: xor of MAC addresses) is "layer2", new choice is "layer3+4", using IP and port information for hashing to select peer. Originally submitted by Jason Gabler for balance-xor mode; modified by Jay Vosburgh to additionally support 802.3ad mode. Jason's original comment is as follows: The attached patch to the Linux Etherchannel Bonding driver modifies the driver's "balance-xor" mode as follows: - alternate hashing policy support for mode 2 * Added kernel parameter "xmit_policy" to allow the specification of different hashing policies for mode 2. The original mode 2 policy is the default, now found in xmit_hash_policy_layer2(). * Added xmit_hash_policy_layer34() This patch was inspired by hashing policies implemented by Cisco, Foundry and IBM, which are explained in Foundry documentation found at: http://www.foundrynet.com/services/documentation/sribcg/Trunking.html#112750 Signed-off-by: Jason Gabler <jygabler@lbl.gov> Signed-off-by: Jay Vosburgh <fubar@us.ibm.com>

2005-06-25[PATCH] Cleanup patch for process freezingChristoph Lameter
1. Establish a simple API for process freezing defined in linux/include/sched.h: frozen(process) Check for frozen process freezing(process) Check if a process is being frozen freeze(process) Tell a process to freeze (go to refrigerator) thaw_process(process) Restart process frozen_process(process) Process is frozen now 2. Remove all references to PF_FREEZE and PF_FROZEN from all kernel sources except sched.h 3. Fix numerous locations where try_to_freeze is manually done by a driver 4. Remove the argument that is no longer necessary from two function calls. 5. Some whitespace cleanup 6. Clear potential race in refrigerator (provides an open window of PF_FREEZE cleared before setting PF_FROZEN, recalc_sigpending does not check PF_FROZEN). This patch does not address the problem of freeze_processes() violating the rule that a task may only modify its own flags by setting PF_FREEZE.
