Ben Tebulin reported:
"Since v3.7.2 on two independent machines a very specific Git
repository fails in 9/10 cases on git-fsck due to an SHA1/memory
failures. This only occurs on a very specific repository and can be
reproduced stably on two independent laptops. Git mailing list ran
out of ideas and for me this looks like some very exotic kernel issue"
and bisected the failure to the backport of commit 53a59fc67f ("mm:
limit mmu_gather batching to fix soft lockups on !CONFIG_PREEMPT").
That commit itself is not actually buggy, but what it does is to make it
much more likely to hit the partial TLB invalidation case, since it
introduces a new case in tlb_next_batch() that previously only ever
happened when running out of memory.
The real bug is that the TLB gather virtual memory range setup is subtly
buggered. It was introduced in commit 597e1c3580 ("mm/mmu_gather:
enable tlb flush range in generic mmu_gather"), and the range handling
was already fixed at least once in commit e6c495a96c ("mm: fix the TLB
range flushed when __tlb_remove_page() runs out of slots"), but that fix
was not complete.
The problem with the TLB gather virtual address range is that it isn't
set up by the initial tlb_gather_mmu() initialization (which didn't get
the TLB range information), but it is set up ad-hoc later by the
functions that actually flush the TLB. And so any such case that forgot
to update the TLB range entries would potentially miss TLB invalidates.
Rather than try to figure out exactly which particular ad-hoc range
setup was missing (I personally suspect it's the hugetlb case in
zap_huge_pmd(), which didn't have the same logic as zap_pte_range()
did), this patch just gets rid of the problem at the source: make the
TLB range information available to tlb_gather_mmu(), and initialize it
when initializing all the other tlb gather fields.
This makes the patch larger, but conceptually much simpler. And the end
result is much more understandable; even if you want to play games with
partial ranges when invalidating the TLB contents in chunks, now the
range information is always there, and anybody who doesn't want to
bother with it won't introduce subtle bugs.
Ben verified that this fixes his problem.

In order to be able to (securely) keep connections alive after
the system was suspended for WoWLAN, we need some additional
APIs. We already have API (ieee80211_gtk_rekey_notify) to tell
wpa_supplicant about the new replay counter if GTK rekeying
was done by the device while the host was asleep, but that's
not sufficient.
If GTK rekeying wasn't done, we need to tell the host about
sequence counters for the GTK (and PTK regardless of rekeying)
that was used while asleep, add ieee80211_set_key_rx_seq() for
that.
If GTK rekeying was done, then we need to be able to disable
the old keys (with ieee80211_remove_key()) and allocate the
new GTK key(s) in mac80211 (with ieee80211_gtk_rekey_add()).
If protocol offload (e.g. ARP) is implemented, then also the
TX sequence counter for the PTK must be updated, using the new
ieee80211_set_key_tx_seq() function.

This patch decouples the power save processing from the frame decryption
by running the decrypt rx handler after sta_process. In the case where
the decryption failed for some reason, the stack used to not process
the PM and MOREDATA bits for that frame. The stack now always performs
power save processing regardless of the decryption result. That means that
encrypted data frames and NULLFUNC frames are now handled in the same way
regarding power save processing, making the stack more robust.

amount of pages increased from 16 to 32 bits.
In MANAGE_PAGES command the input_num_entries and output_num_entries fields
sizes changed from 16 to 32 bits and the PAS tables offset changed to 0x10.
In the pages request event the num_pages field also changed to 32 bits.
In the HCA-capabilities-layout the size and location of max_qp_mcg field has
been changed to support 24 bits.
This patch isn't compatible with firmware versions < 5; however, it turns out that the
first GA firmware we will publish will not support previous versions so this should be OK.

The recent fix d9bf5f1309 "tun: compare with 0 instead of total_len" is
not totally correct. Because "len" and "sizeof()" are size_t type, that
means they are never less than zero.

Commit d8af4dfd8 ("net/tg3: Fix kernel crash") introduced a possible
NULL pointer dereference in tg3 driver when !netdev || !netif_running(netdev)
condition is met and netdev is NULL. Then, the jump to the 'done' label
calls dev_close() with a netdevice that is NULL. Therefore, only call
dev_close() when we have a netdevice, but one that is not running.

The documentation for antenna diversity says:
"The decision of diversity is done at 802.11 preamble. So, for
11G/11B, for every MAC packet hardware will do a decision. But in
11N with aggregation, the decision is made only at the preamble and
all other MPDUs will use the same LNA as the first MPDU."
Make use of rs_firstaggr to avoid needlessly scanning for LNA
changes.

In case a descriptor has the "done" bit clear and the
next descriptor has it set, we drop both of them. If
the packet that is received after these two packets
is dropped for some reason, "discard_next" will not cleared.
