Pull kdump fixes from Peter Anvin:
"The kexec/kdump people have found several problems with the support
for loading over 4 GiB that was introduced in this merge cycle. This
is partly due to a number of design problems inherent in the way the
various pieces of kdump fit together (it is pretty horrifically manual
in many places.)
After a *lot* of iterations this is the patchset that was agreed upon,
but of course it is now very late in the cycle. However, because it
changes both the syntax and semantics of the crashkernel option, it
would be desirable to avoid a stable release with the broken
interfaces."
I'm not happy with the timing, since originally the plan was to release
the final 3.9 tomorrow. But apparently I'm doing an -rc8 instead...

Pull x86 fixes from Peter Anvin:
"Three groups of fixes:
1. Make sure we don't execute the early microcode patching if family
< 6, since it would touch MSRs which don't exist on those

2. The Xen partial emulation of HyperV can be dealt with more
gracefully than just disabling the driver.
3. More EFI variable space magic. In particular, variables hidden

Commit 257b5358b32f ("scm: Capture the full credentials of the scm
sender") changed the credentials passing code to pass in the effective
uid/gid instead of the real uid/gid.
Obviously this doesn't matter most of the time (since normally they are
the same), but it results in differences for suid binaries when the wrong
uid/gid ends up being used.
This just undoes that (presumably unintentional) part of the commit.

For each CPU vendor that implements CPU microcode patching, there will
be a minimum family for which this is implemented. Verify this
minimum level of support.
This can be done in the dispatch function or early in the application
functions. Doing the latter turned out to be somewhat awkward because
of the ineviable split between the BSP and the AP paths, and rather
than pushing deep into the application functions, do this in
the dispatch function.

When building ax88796 on an ARM platform with 64-bit resource_size_t,
we currently get
drivers/net/ethernet/8390/ax88796.c:875: undefined reference to `__aeabi_uldivmod'
because we do a division on the length of the MMIO resource.
Since we know that this resource is very short, using an
"unsigned long" instead of "resource_size_t" is entirely
sufficient, and avoids this link-time error.

Bjørn Mork says:
====================
This series adds workarounds for 3 different firmware bugs, each
preventing the affected devices from working at all. I therefore
humbly request that these fixes go to stable-3.8 (if still
maintained) and 3.9 (either via net if still possible, or via
stable if not).
All 3 workarounds are applied to all devices supported by the driver.
Adding quirks for specific devices was considered as an alternative,
but was rejected because we have too little information about the
exact distribution of the buggy firmwares. All we know is that the
same bug shows up in devices from at least 3 different, and presumably
independent, vendors.
The workarounds have instead been designed to automatically apply
when necessary, and to have as little impact as possible on unaffected
devices. The series has been tested on a number of devices both with
and without these bugs.
The series should apply cleanly to net/master, net-next/master and
stable/linux-3.8.y

We normally trust and use the CDC functional descriptors provided by a
number of devices. But some of these will erroneously list the address
reserved for the device end of the link. Attempting to use this on
both the device and host side will naturally not work.
Work around this bug by ignoring the functional descriptor and assign a
random address instead in this case.

The bogus address is always the same, and matches the address
suggested by many devices as a default address. It is likely a
hardcoded firmware default.
The circumstances where this bug has been observed indicates that
the trigger is related to timing or some other factor the host
cannot control. Repeating the exact same configuration sequence
that caused it to trigger once, will not necessarily cause it to
trigger the next time. Reproducing the bug is therefore difficult.
This opens up a possibility that the bug is more common than we can
confirm, because affected devices often will work properly again
after a reset. A procedure most users are likely to try out before
reporting a bug.
Unconditionally rewriting the destination address if the first digit
of the received packet is 0, is considered an acceptable compromise
since we already have to inspect this digit. The simplification will
cause unnecessary rewrites if the real address starts with 0, but this
is still better than adding additional tests for this particular case.

A number of LTE devices from different vendors all suffer from the
same firmware bug: Most of the packets received from the device while
it is attached to a LTE network will not have an ethernet header. The
devices work as expected when attached to 2G or 3G networks, sending
an ethernet header with all packets.
This driver is not aware of which network the modem attached to, and
even if it were there are still some packet types which are always
received with the header intact.
All devices supported by this driver have severely limited
networking capabilities:
- can only transmit IPv4, IPv6 and possibly ARP
- can only support a single host hardware address at any time
- will only do point-to-point communcation with the host
Because of this, we are able to reliably identify any bogus raw IP
packets by simply looking at the 4 IP version bits. All we need to
do is to avoid 4 or 6 in the first digit of the mac address. This
workaround ensures this, and fix up the received packets as necessary.
Given the distribution of the bug, it is believed that the source is
the chipset vendor. The devices which are verified to be affected are:
Huawei E392u-12 (Qualcomm MDM9200)
Pantech UML290 (Qualcomm MDM9600)
Novatel USB551L (Qualcomm MDM9600)
Novatel E362 (Qualcomm MDM9600)
It is believed that the bug depend on firmware revision, which means
that possibly all devices based on the above mentioned chipset may be
affected if we consider all available firmware revisions.
The information about affected devices and versions is likely
incomplete. As the additional overhead for packets not needing this
fixup is very small, it is considered acceptable to apply the
workaround to all devices handled by this driver.

The "reason" can come from skb->data[] and it hasn't been capped so it
can be from 0-255 instead of just 0-6. For example in irlmp_state_dtr()
the code does:
reason = skb->data[3];
...
irlmp_disconnect_indication(self, reason, skb);
Also LMREASON has a couple other values which don't have entries in the
irlmp_reasons[] array. And 0xff is a valid reason as well which means
"unknown".
So far as I can see we don't actually care about "reason" except for in

As reported by Dave Kleikamp, when we emit cross calls to do batched
TLB flush processing we have a race because we do not synchronize on
the sibling cpus completing the cross call.
So meanwhile the TLB batch can be reset (tb->tlb_nr set to zero, etc.)
and either flushes are missed or flushes will flush the wrong
addresses.
Fix this by using generic infrastructure to synchonize on the
completion of the cross call.
This first required getting the flush_tlb_pending() call out from
switch_to() which operates with locks held and interrupts disabled.
The problem is that smp_call_function_many() cannot be invoked with
IRQs disabled and this is explicitly checked for with WARN_ON_ONCE().
We get the batch processing outside of locked IRQ disabled sections by
using some ideas from the powerpc port. Namely, we only batch inside
of arch_{enter,leave}_lazy_mmu_mode() calls. If we're not in such a
region, we flush TLBs synchronously.
1) Get rid of xcall_flush_tlb_pending and per-cpu type
implementations.
2) Do TLB batch cross calls instead via:
smp_call_function_many()
tlb_pending_func()
__flush_tlb_pending()
3) Batch only in lazy mmu sequences:
a) Add 'active' member to struct tlb_batch
b) Define __HAVE_ARCH_ENTER_LAZY_MMU_MODE
c) Set 'active' in arch_enter_lazy_mmu_mode()
d) Run batch and clear 'active' in arch_leave_lazy_mmu_mode()
e) Check 'active' in tlb_batch_add_one() and do a synchronous
flush if it's clear.
4) Add infrastructure for synchronous TLB page flushes.
a) Implement __flush_tlb_page and per-cpu variants, patch
as needed.
b) Likewise for xcall_flush_tlb_page.
c) Implement smp_flush_tlb_page() to invoke the cross-call.
d) Wire up global_flush_tlb_page() to the right routine based
upon CONFIG_SMP
5) It turns out that singleton batches are very common, 2 out of every
3 batch flushes have only a single entry in them.
The batch flush waiting is very expensive, both because of the poll
on sibling cpu completeion, as well as because passing the tlb batch
pointer to the sibling cpus invokes a shared memory dereference.
Therefore, in flush_tlb_pending(), if there is only one entry in
the batch perform a completely asynchronous global_flush_tlb_page()
instead.

cyc_to_sched_clock() is called by sched_clock() and cyc_to_ns()
is called by cyc_to_sched_clock(). I suspect that some compilers
inline both of these functions into sched_clock() and so we've
been getting away without having a notrace marking. It seems that
my compiler isn't inlining cyc_to_sched_clock() though, so I'm
hitting a recursion bug when I enable the function graph tracer,
causing my system to crash. Marking these functions notrace fixes
it. Technically cyc_to_ns() doesn't need the notrace because it's
already marked inline, but let's just add it so that if we ever
remove inline from that function it doesn't blow up.

* Skip broadcast/multicast locally generated traffic in the rpfilter,
(closes netfilter bugzilla #814), from Florian Westphal.

John W. Linville says:
====================
A few stragglers hoping for 3.9, somewhat delayed due to my travels...
On the mac80211 bits, Johannes says:
"Sadly, I have another pull request -- the idle handling fix broke LED
handling in some cases."
and:
"Yet one more!
This fixes a fairly important/annoying bug -- when roaming between
multiple APs of the same network, the system could get stuck thinking it
was connected to the old one while it really wasn't."
On top of that...
Arend sends a brcmfmac patch that removes advertising a feature that
isn't actually fully supported, and a brcmsmac patch that rearranges
code to request firmware at IFF_UP to play more nicely with being
built into the kernel.
Felix gives us a minor ath9k_htc fix to support the newly released
open source firmware, and an ath9k_hw initvals fix to improve device
stability.
Rafał Miłecki provides a fix for an ssb regression that caused a
serious performance problem with b43.
Zefir Kurtisi offers an ath9k fix to change some kmalloc flags to
allow the DFS detector to be called in softirq context.
Please let me know if there are problems. If these don't make 3.9,
I'll just pull them into wireless-next -- just let me know if you
want to do it that way!

commit bd090dfc634d (tcp: tcp_replace_ts_recent() should not be called
from tcp_validate_incoming()) introduced a TS ecr bug in slow path
processing.
1 A > B P. 1:10001(10000) ack 1 <nop,nop,TS val 1001 ecr 200>
2 B < A . 1:1(0) ack 1 win 257 <sack 9001:10001,TS val 300 ecr 1001>
3 A > B . 1:1001(1000) ack 1 win 227 <nop,nop,TS val 1002 ecr 200>
4 A > B . 1001:2001(1000) ack 1 win 227 <nop,nop,TS val 1002 ecr 200>
(ecr 200 should be ecr 300 in packets 3 & 4)
Problem is tcp_ack() can trigger send of new packets (retransmits),
reflecting the prior TSval, instead of the TSval contained in the
currently processed incoming packet.
Fix this by calling tcp_replace_ts_recent() from tcp_ack() after the
checks, but before the actions.

This is my example conversion of a few existing mmap users. The
fb_mmap() case is a good example because it is a bit more complicated
than some: fb_mmap() mmaps one of two different memory areas depending
on the page offset of the mmap (but happily there is never any mixing of
the two, so the helper function still works).

This is my example conversion of a few existing mmap users. The mtdchar
case is actually disabled right now (and stays disabled), but I did it
because it showed up on my "git grep", and I was familiar with the code
due to fixing an overflow problem in the code in commit 9c603e53d380
("mtdchar: fix offset overflow detection").

Alex Efros reported rpfilter module doesn't match following packets:
IN=br.qemu SRC=192.168.2.1 DST=192.168.2.255 [ .. ]
(netfilter bugzilla #814).
Problem is that network stack arranges for the locally generated broadcasts
to appear on the interface they were sent out, so the IFF_LOOPBACK check
doesn't trigger.
As -m rpfilter is restricted to PREROUTING, we can check for existing
rtable instead, it catches locally-generated broad/multicast case, too.

The type when timeout support was enabled, could not list all elements,
just the first ones which could fit into one netlink message: it just
did not continue listing after the first message.

Since commit 6b923cb7188d46 (bonding: support for IPv6 transmit hashing)
bonding doesn't properly hash traffic in forwarding setups.
Vitaly V. Bursov diagnosed that skb_network_header_len() returned 0 in
this case.
More generally, the transport header might not be in the skb head.
Use pskb_may_pull() & skb_header_pointer() to get it right, and use
proto_ports_offset() in bond_xmit_hash_policy_l34() to get support for
more protocols than TCP and UDP.

This fixes 2 issues regarding bnx2x's status blocks:
1. ethtool -c caused corruption of status blocks in FW RAM.
2. when using multi-CoS, the configuration of the timeout values of
status blocks is incorrect, harming the coalescing of interrupts
for such CoSs.
