When MCS rates start to get bad in 2.4 GHz because of long range or
strong interference, CCK rates can be a lot more robust.
This patch adds a pseudo MCS group containing CCK rates (long preamble
in the lower 4 slots, short preamble in the upper slots).

cfg80211_find_vendor_ie() was checking only that the vendor IE would
fit in the remaining IEs buffer. If a corrupt includes a vendor IE
that is too small, we could potentially overrun the IEs buffer.
Fix this by checking that the vendor IE fits in the reported IE length
field and skip it otherwise.

A user reported the following oops when a backup process reads
/proc/kcore:
BUG: unable to handle kernel paging request at ffffbb00ff33b000
IP: [<ffffffff8103157e>] kern_addr_valid+0xbe/0x110
[...]
Call Trace:
[<ffffffff811b8aaa>] read_kcore+0x17a/0x370

[<ffffffff811517f3>] sys_read+0x53/0xa0
[<ffffffff81449692>] system_call_fastpath+0x16/0x1b
Investigation determined that the bug triggered when reading
system RAM at the 4G mark. On this system, that was the first
address using 1G pages for the virt->phys direct mapping so the
PUD is pointing to a physical address, not a PMD page.
The problem is that the page table walker in kern_addr_valid() is
not checking pud_large() and treats the physical address as if
it was a PMD. If it happens to look like pmd_none then it'll
silently fail, probably returning zeros instead of real data. If
the data happens to look like a present PMD though, it will be
walked resulting in the oops above.
This patch adds the necessary pud_large() check.
Unfortunately the problem was not readily reproducible and now
they are running the backup program without accessing
/proc/kcore so the patch has not been validated but I think it
makes sense.

Starting with win8, vmbus interrupts can be delivered on any VCPU in the guest
and furthermore can be concurrently active on multiple VCPUs. Support this
interrupt delivery model by setting up a separate IDT entry for Hyper-V vmbus.
interrupts. I would like to thank Jan Beulich <JBeulich@suse.com> and
Thomas Gleixner <tglx@linutronix.de>, for their help.
In this version of the patch, based on the feedback, I have merged the IDT

Xen emulates Hyper-V to host enlightened Windows. Looks like this
emulation may be turned on by default even for Linux guests. Check and
fail Hyper-V detection if we are on Xen.
[ hpa: the problem here is that Xen doesn't emulate Hyper-V well

Enable hyperv_clocksource only if its advertised as a feature.
XenServer 6 returns the signature which is checked in
ms_hyperv_platform(), but it does not offer all features. Currently the
clocksource is enabled unconditionally in ms_hyperv_init_platform(), and
the result is a hanging guest.
Hyper-V spec Bit 1 indicates the availability of Partition Reference
Counter. Register the clocksource only if this bit is set.
The guest in question prints this in dmesg:
[ 0.000000] Hypervisor detected: Microsoft HyperV
[ 0.000000] HyperV: features 0x70, hints 0x0
This bug can be reproduced easily be setting 'viridian=1' in a HVM domU
.cfg file. A workaround without this patch is to boot the HVM guest with
'clocksource=jiffies'.

The gfar_stats struct is only used in copying out data
via ethtool. It is declared as the extra stats, followed
by the rmon stats. However, the rmon stats are never
actually ever used in the driver; instead the rmon data
is a u32 register read that is cast directly into the
ethtool buf.
It seems the only reason rmon is in the struct at all is
to give the offset(s) at which it should be exported into
the ethtool buffer. But note gfar_stats doesn't contain
a gfar_extra_stats as a substruct -- instead it contains
a u64 array of equal element count. This implicitly means
we have two independent declarations of what gfar_extra_stats
really is. Rather than have this duality, we already have
defines which give us the offset directly, and hence do not
need the struct at all.
Further, since we know the extra_stats is unconditionally
always present, we can write it out to the ethtool buf
1st, and then optionally write out the rmon data. There
is no need for two independent loops, both of which are
simply copying out the extra_stats to buf offset zero.
This also helps pave the way towards allowing the extra
stats fields to be converted to atomic64_t values, without
having their types directly influencing the ethtool stats
export code (gfar_fill_stats) that expects to deal with u64.

Current act_police uses rate table computed by the "tc" userspace
program, which has the following issue:
The rate table has 256 entries to map packet lengths to token (time
units). With TSO sized packets, the 256 entry granularity leads to
loss/gain of rate, making the token bucket inaccurate.
Thus, instead of relying on rate table, this patch explicitly computes
the time and accounts for packet transmission times with nanosecond
granularity.

The designed workflow for the caches in kmemcg is: register it with
memcg_register_cache() if kmemcg is already available or later on when a
new kmemcg appears at memcg_update_cache_sizes() which will handle all
caches in the system. The caches created at boot time will be handled
by the later, and the memcg-caches as well as any system caches that are
registered later on by the former.
There is a bug, however, in memcg_register_cache: we correctly set up
the array size, but do not mark the cache as a root cache.
This means that allocations for any cache appearing late in the game
will see memcg->memcg_params->is_root_cache == false, and in particular,
trigger VM_BUG_ON(!cachep->memcg_params->is_root_cache) in
__memcg_kmem_cache_get.
The obvious fix is to include the missing assignment.

commit (32f5376 netfilter: nf_ct_helper: disable automatic helper
re-assignment of different type) broke transparent proxy scenarios.
For example, initial helper lookup might yield "ftp" (dport 21),
while re-lookup after REDIRECT yields "ftp-2121".
This causes the autoassign code to toss the ftp helper, even
though these are just different instances of the same helper.
Change the test to check for the helper function address instead
of the helper address, as suggested by Pablo.

Until now, the MPC5200 FEC ethernet driver relied upon the bootloader
(U-Boot) to write the MAC address into the ethernet controller
registers. The Linux driver should not rely on such a thing. So
lets read the MAC address from the DT as it should be done here.
The following priority is now used to read the MAC address:
1) First, try OF node MAC address, if not present or invalid, then:
2) Read from MAC address registers, if invalid, then:
3) Log a warning message, and choose a random MAC address.
This fixes a problem with a MPC5200 board that uses the SPL U-Boot
version without FEC initialization before Linux booting for
boot speedup.
Additionally a status line is now be printed upon successful
driver probing, also displaying this MAC address.

stream... Hopefully the will still make it! :-)
There are three mac80211 fixes pulled from Johannes:
"Here are three fixes still for the 3.8 stream, the fix from Cong Ding
for the bad sizeof (Stephen Hemminger had pointed it out before but I'd
promptly forgotten), a mac80211 managed-mode channel context usage fix
where a downgrade would never stop until reaching non-HT and a bug in
the channel determination that could cause invalid channels like HT40+
on channel 11 to be used."
Also included is a mwl8k fix that avoids an oops when using mwl8k
devices that only support the 5 GHz band.
Please let me know if there are problems!

Using /dev/pstore as a mount point for the pstore filesystem is slightly
awkward. We don't normally mount filesystems in /dev/ and the /dev/pstore
file isn't created automatically by anything. While this method will
still work, we can create a persistent mount point in sysfs. This will
put pstore on par with things like cgroups and efivarfs.

The original fix that was applied for setting gso_type required more change
than necessary because it was assumed ixgbe does RSC on IPv6 frames and this
is not correct. RSC is only supported with IPv4/TCP frames only. As such we
can simplify the fix and avoid the unnecessary move of eth_type_trans.
The previous patch "ixgbe: fix gso type" and this patch reduce the entire fix
to one line that sets gso_type to TCPV4 if the frame is RSC.
