General Software writes their own VSA2 module for their version
of the Geode BIOS, which returns a different ID then the standard
VSA2. This was causing the framebuffer driver to break for most
GSW boards.

When a 64-bit x86 processor runs in 32-bit PAE mode, a pte can
potentially have the same number of physical address bits as the
64-bit host ("Enhanced Legacy PAE Paging"). This means, in theory,
we could have up to 52 bits of physical address in a pte.
The 32-bit kernel uses a 32-bit unsigned long to represent a pfn.
This means that it can only represent physical addresses up to 32+12=44
bits wide. Rather than widening pfns everywhere, just set 2^44 as the
Linux x86_32-PAE architectural limit for physical address size.
This is a bugfix for two cases:
1. running a 32-bit PAE kernel on a machine with
more than 64GB RAM.
2. running a 32-bit PAE Xen guest on a host machine with
more than 64GB RAM
In both cases, a pte could need to have more than 36 bits of physical,
and masking it to 36-bits will cause fairly severe havoc.

Max of promiscuity and allmulti plus positive @inc can cause overflow.
Fox example: when allmulti=0xFFFFFFFF, any caller give dev_set_allmulti() a
positive @inc will cause allmulti be off.
This is not what we want, though it's rare case.
The fix is that only negative @inc will cause allmulti or promiscuity be off
and when any caller makes the counters touch the roof, we return error.
Change of v2:
Change void function dev_set_promiscuity/allmulti to return int.
So callers can get the overflow error.
Caller's fix will be done later.
Change of v3:
1. Since we return error to caller, we don't need to print KERN_ERROR,
KERN_WARNING is enough.
2. In dev_set_promiscuity(), if __dev_set_promiscuity() failed, we
return at once.

Permit bonding to function rationally if max_bonds is set to
zero. This will load the module, but create no master devices (which can
be created via sysfs).
Requires some change to bond_create_sysfs; currently, the
netdev sysfs directory is determined from the first bonding device created,
but this is no longer possible. Instead, an interface from net/core is
created to create and destroy files in net_class.
Based on a patch submitted by Phil Oester <kernel@linuxaces.com>.
Modified by Jay Vosburgh to fix the sysfs issue mentioned above and to
update the documentation.

Add NETDEV_BONDING_FAILOVER event to be used in a successive patch
by bonding to announce fail-over for the active-backup mode through the
netdev events notifier chain mechanism. Such an event can be of use for the
RDMA CM (communication manager) to let native RDMA ULPs (eg NFS-RDMA, iSER)
always be aligned with the IP stack, in the sense that they use the same
ports/links as the stack does. More usages can be done to allow monitoring
tools based on netlink events being aware to bonding fail-over.

ROSE network is organized through nodes connected via hamradio or Internet.
AX25 packet radio frames sent to a remote ROSE address destination are routed
through these nodes.
Without the present patch, automatic routing mechanism did not work optimally
due to an improper parameter checking.
rose_get_neigh() function is called either by rose_connect() or by
rose_route_frame().
In the case of a call from rose_connect(), f0 timer is checked to find if a connection
is already pending. In that case it returns the address of the neighbour, or returns a NULL otherwise.
When called by rose_route_frame() the purpose was to route a packet AX25 frame
through an adjacent node given a destination rose address.
However, in that case, t0 timer checked does not indicate if the adjacent node
is actually connected even if the timer is not null. Thus, for each frame sent, the
function often tried to start a new connexion even if the adjacent node was already connected.
The patch adds a "new" parameter that is true when the function is called by
rose route_frame().
This instructs rose_get_neigh() to check node parameter "restarted".
If restarted is true it means that the route to the destination address is opened via a neighbour
node already connected.
If "restarted" is false the function returns a NULL.
In that case the calling function will initiate a new connection as before.
This results in a fast routing of frames, from nodes to nodes, until
destination is reached, as originaly specified by ROSE protocole.

Fix three ct_extend/NAT extension related races:
- When cleaning up the extension area and removing it from the bysource hash,
the nat->ct pointer must not be set to NULL since it may still be used in
a RCU read side
- When replacing a NAT extension area in the bysource hash, the nat->ct
pointer must be assigned before performing the replacement
- When reallocating extension storage in ct_extend, the old memory must
not be freed immediately since it may still be used by a RCU read side

Three major portions to this change:
1) Add IW_EV_COMPAT_LCP_LEN, IW_EV_COMPAT_POINT_OFF,
and IW_EV_COMPAT_POINT_LEN helper defines.
2) Delete iw_stream_check_add_*(), they are unused.
3) Add iw_request_info argument to iwe_stream_add_*(), and use it to
size the event and pointer lengths correctly depending upon whether
IW_REQUEST_FLAG_COMPAT is set or not.
4) The mechanical transformations to the drivers and wireless stack
bits to get the iw_request_info passed down into the routines
modified in #3. Also, explicit references to IW_EV_LCP_LEN are
replaced with iwe_stream_lcp_len(info).
With a lot of help and bug fixes from Masakazu Mokuno.
