[PATCH] pcnet_cs.c: IRQ handler optimization
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.

[PATCH] net/sis900: Use the DMA_32BIT_MASK constant
Use the DMA_32BIT_MASK constant from dma-mapping.h when calling

This patch includes dma-mapping.h explicitly because it caused errors

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.

bonding: xor/802.3ad improved slave hash
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:

freezing(process) Check if a process is being frozen
freeze(process) Tell a process to freeze (go to refrigerator)
thaw_process(process) Restart process

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!

Use msleep() instead of schedule_timeout() to guarantee the task delays as
