Some BIOS's break if Wake On Lan is enabled, and the machine
can't boot. Better to have some user's have to call ethtool to
enable WOL than to break a single user's boot.

Change bond_mii_monitor to not hold any locks when calling rtnl_unlock,

Fix the handling of rtnl and the bonding_rwsem to always be acquired
in a consistent order (rtnl, then bonding_rwsem).

The existing code sometimes acquired them in this order, and sometimes
in the opposite order, which opens a window for deadlock between ifenslave
and sysfs.

	A recent change to add an additional hash policy modified
bond_parse_parm, but it now does not correctly match parameters passed in

	Rewrote bond_parse_parm to handle (a) parameter matches that

sysfs input often has a trailing newline).

	alb_fasten_mac_swap (actually rlb_teach_disabled_mac_on_primary)

	Fix the functions that store the primary and active slave
options via sysfs to hold the correct locks in the correct order.

	The bond_change_active_slave and bond_select_active_slave
functions both require rtnl, bond->lock for read and curr_slave_lock for
write_bh, and no other locks.  This is so that the lower level
mode-specific functions (notably for balance-alb mode) can release locks
down to just rtnl in order to call, e.g., dev_set_mac_address with the
locks it expects (rtnl only).

This patch puts #ifdef CONFIG_DEBUG_VM around a check in vm_normal_page
that verifies that a pfn is valid.  This patch increases performance of the
page fault microbenchmark in lmbench by 13% and overall dbench performance
by 7% on s390x.  pfn_valid() is an expensive operation on s390 that needs a
high double digit amount of CPU cycles.  Nick Piggin suggested that
pfn_valid() involves an array lookup on systems with sparsemem, and
therefore is an expensive operation there too.

The check looks like a clear debug thing to me, it should never trigger on
regular kernels.  And if a pte is created for an invalid pfn, we'll find
out once the memory gets accessed later on anyway.  Please consider
inclusion of this patch into mm.

The culprit was zone_batchsize() which were annotated __devinit but used

to drop the annotation of zone_batchsize() so we know it is always valid to

- Move alignment to page size of init data outside ifdef for BLK_DEV_INITRD.
  The reservation up to page size of memory after init data was previously
  not done if BLK_DEV_INITRD was undefined.
  This caused a kernel oops when init memory pages were freed after startup,
  data placed in the same page as the last init memory would also be freed
  and reused, with disastrous results.

- Use macros for initcalls and .text sections.

- Replace hardcoded page size constant with PAGE_SIZE define.

- Change include/asm-cris/page.h to use the _AC macro to instead
  of testing __ASSEMBLY__.

When the cpufreq driver starts up at boot time, it calls into the default
governor which might not be initialised yet.  This hurts when the
governor's worker function relies on memory that is not yet set up by its
init function.

This migrates all governors from module_init() to fs_initcall() when being
the default, as was already done in cpufreq_performance when it was the
only possible choice.  The performance governor is always initialized early
because it might be used as fallback even when not being the default.

Fixes at least one actual oops where ondemand is the default governor and
cpufreq_governor_dbs() uses the uninitialised kondemand_wq work-queue
during boot-time.

a queue full condition and you have a recipe to leak quickly.

Let's release every pending Tx descriptor which has been given
back to the host CPU by the network controller. The xmit handler

Fix a buffer overflow in mutli-packet handling code.  The overflow can
only happen with eGalax devices and is even there very unlikely (only
non-report packet are affected any only when truncated after the first
byte).

Also changes the mutli-packet handling code not to drop unknown packets,
but rather just drop one byte.  This allows synchronizing on report packets
in the data stream.  It's required for some egalax devices to work at all.

Also remove the pointless 'flags' member of the device struct and set the
version number to 0.6, plus some minor cleanups.

Devices like the HP Integrated Remote Console Virtual Mouse, which are
standard equipment on all Proliant and Integrity servers, produce
absolute coordinates instead of relative coordinates.  This is done to
synchronize the position of the mouse cursor on the client desktop
with the mouse cursor position on the server.  Mousedev is not
designed to pass those absolute events directly to X, but it can
translate them into relative movements.  It currently does this for
tablet like devices and touchpads.  This patch merely tells it to also
include a device with ABS_X, ABS_Y, and mouse buttons in its list of
devices to process input for.

This patch enables the mouse pointer to move when using the remote
