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.

Use the DMA_{64,32}BIT_MASK constants from dma-mapping.h when calling pci_set_dma_mask() or pci_set_consistent_dma_mask() This patch includes dma-mapping.h explicitly because it caused errors on some architectures otherwise.

Make sure the code compiles with and without ARLAN_ENTRY_EXIT_DEBUGGING. Only provide parameter descriptions when parameters are defined. Remove "arlan_"-prefix to shape up built-in parameter names: arlan.arlan_debug -> arlan.debug arlan.arlan_EEPROM_bad -> arlan.EEPROM_bad arlan.arlan_entry_and_exit_debug -> arlan.entry_and_exit_debug arlan.arlan_entry_debug -> arlan.entry_debug arlan.arlan_exit_debug -> arlan.exit_debug Signed-off-by:Magnus Damm <damm@opensource.se>

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.

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#112750Signed-off-by:Jason Gabler <jygabler@lbl.gov> Signed-off-by:

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. This is not clean in an SMP environment. freeze(process) is therefore not SMP safe! Signed-off-by:
