struct gnet_stats_rate_est contains u32 fields, so the bytes per second
field can wrap at 34360Mbit.
Add a new gnet_stats_rate_est64 structure to get 64bit bps/pps fields,
and switch the kernel to use this structure natively.
This structure is dumped to user space as a new attribute :
TCA_STATS_RATE_EST64
Old tc command will now display the capped bps (to 34360Mbit), instead
of wrapped values, and updated tc command will display correct
information.
Old tc command output, after patch :

As we know, netlink sockets are private resource of
net namespace, they can communicate with each other
only when they in the same net namespace. this works
well until we try to add namespace support for other
subsystems which use netlink.
Don't like ipv4 and route table.., it is not suited to
make these subsytems belong to net namespace, Such as
audit and crypto subsystems,they are more suitable to
user namespace.
So we must have the ability to make the netlink sockets
in same user namespace can communicate with each other.
This patch adds a new function pointer "compare" for
netlink_table, we can decide if the netlink sockets can
communicate with each other through this netlink_table
self-defined compare function.
The behavior isn't changed if we don't provide the compare
function for netlink_table.

Merge tag 'stable/for-linus-3.10-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen
Pull Xen fixes from Konrad Rzeszutek Wilk:
- Use proper error paths
- Clean up APIC IPI usage (incorrect arguments)
- Delay XenBus frontend resume is backend (xenstored) is not running
- Fix build error with various combinations of CONFIG_
* tag 'stable/for-linus-3.10-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen:
xenbus_client.c: correct exit path for xenbus_map_ring_valloc_hvm
xen-pciback: more uses of cached MSI-X capability offset
xen: Clean up apic ipi interface
xenbus: save xenstore local status for later use
xenbus: delay xenbus frontend resume if xenstored is not running
xmem/tmem: fix 'undefined variable' build error.
The following warning was seen on 3.9 when a corrected PCIe error was being
handled by the AER subsystem.
WARNING: at .../drivers/pci/search.c:214 pci_get_dev_by_id+0x8a/0x90()
This occurred because a call to pci_get_domain_bus_and_slot() was added to
cper_print_pcie() to setup for the call to cper_print_aer(). The warning
showed up because cper_print_pcie() is called in an interrupt context and
pci_get* functions are not supposed to be called in that context.
The solution is to move the cper_print_aer() call out of the interrupt
context and into aer_recover_work_func() to avoid any warnings when calling
pci_get* functions.
