6c7080a61f firmware: fix directory creation rule matching with make 3.82
Attempting to run 'firmware_install' with CONFIG_USB_SERIAL_TI=y when
using make 3.82 results in an error

make[2]: *** No rule to make target `/lib/firmware/./', needed by
`/lib/firmware/ti_3410.fw'.  Stop.

It turns out make 3.82 is picky when matching directory names with
trailing slashes as a result, where make 3.81 would handle this
correctly make 3.82 does not find the rule needed to create the
directory.

The './' seen in the error is added by $(dir) for firmware which
resides in the base firmware src directory, such as
ti_3410.fw.ihex. By performing $(dir) after we prepend the
$(INSTALL_FW_PATH) we can ensure we don't end up with a './' in the
middle of the path and the directory will be properly created.

This change works with make 3.81 and should work with previous
versions as well.

015618b902 ALSA: snd-usb: Fix URB cancellation at stream start
Commit e9ba389c5 ("ALSA: usb-audio: Fix scheduling-while-atomic bug in
PCM capture stream") fixed a scheduling-while-atomic bug that happened
when snd_usb_endpoint_start was called from the trigger callback, which
is an atmic context. However, the patch breaks the idea of the endpoints
reference counting, which is the reason why the driver has been
refactored lately.

Revert that commit and let snd_usb_endpoint_start() take care of the URB
cancellation again. As this function is called from both atomic and
non-atomic context, add a flag to denote whether the function may sleep.

2b60af0178 netfilter: nf_conntrack_ipv6: fix tracking of ICMPv6 error messages containing fragments
ICMPv6 error messages are tracked by extracting the conntrack tuple of
the inner packet and looking up the corresponding conntrack entry. Tuple
extraction uses the ->get_l4proto() callback, which in case of fragments
returns NEXTHDR_FRAGMENT instead of the upper protocol, even for the
first fragment when the entire next header is present, resulting in a
failure to find the correct connection tracking entry.

This patch changes ipv6_get_l4proto() to use ipv6_skip_exthdr() instead
of nf_ct_ipv6_skip_exthdr() in order to skip fragment headers when the
fragment offset is zero.

4cdd34084d netfilter: nf_conntrack_ipv6: improve fragmentation handling
The IPv6 conntrack fragmentation currently has a couple of shortcomings.
Fragmentes are collected in PREROUTING/OUTPUT, are defragmented, the
defragmented packet is then passed to conntrack, the resulting conntrack
information is attached to each original fragment and the fragments then
continue their way through the stack.

Helper invocation occurs in the POSTROUTING hook, at which point only
the original fragments are available. The result of this is that
fragmented packets are never passed to helpers.

This patch improves the situation in the following way:

- If a reassembled packet belongs to a connection that has a helper
  assigned, the reassembled packet is passed through the stack instead
  of the original fragments.

- During defragmentation, the largest received fragment size is stored.
  On output, the packet is refragmented if required. If the largest
  received fragment size exceeds the outgoing MTU, a "packet too big"
  message is generated, thus behaving as if the original fragments
  were passed through the stack from an outside point of view.

- The ipv6_helper() hook function can't receive fragments anymore for
  connections using a helper, so it is switched to use ipv6_skip_exthdr()
  instead of the netfilter specific nf_ct_ipv6_skip_exthdr() and the
  reassembled packets are passed to connection tracking helpers.

The result of this is that we can properly track fragmented packets, but
still generate ICMPv6 Packet too big messages if we would have before.

This patch is also required as a precondition for IPv6 NAT, where NAT
helpers might enlarge packets up to a point that they require
fragmentation. In that case we can't generate Packet too big messages
since the proper MTU can't be calculated in all cases (f.i. when
changing textual representation of a variable amount of addresses),
so the packet is transparently fragmented iff the original packet or
fragments would have fit the outgoing MTU.

590e3f79a2 ipvs: IPv6 MTU checking cleanup and bugfix
Cleaning up the IPv6 MTU checking in the IPVS xmit code, by using
a common helper function __mtu_check_toobig_v6().

The MTU check for tunnel mode can also use this helper as
ntohs(old_iph->payload_len) + sizeof(struct ipv6hdr) is qual to
skb->len.  And the 'mtu' variable have been adjusted before
calling helper.

Notice, this also fixes a bug, as the the MTU check in ip_vs_dr_xmit_v6()
were missing a check for skb_is_gso().

This bug e.g. caused issues for KVM IPVS setups, where different
Segmentation Offloading techniques are utilized, between guests,
via the virtio driver.  This resulted in very bad performance,
due to the ICMPv6 "too big" messages didn't affect the sender.

4a68a74ba0 gma500: Consider CRTC initially active.
[this one ideally should make 3.6 - it fixes the very annoying mode setting bug]

This causes the pipe to be forced off prior to initial mode set, which
roughly mirrors the behavior of the i915 driver.  It fixes initial mode
setting on my Intel DN2800MT (Cedarview) board.  Without it, mode
setting triggers an out-of-range error from the monitor for most modes,
but only on initial configuration (i.e. they can be configured
successfully from userspace after that).

6fb8a90aa3 xfs: fix race while discarding buffers [V4]
While xfs_buftarg_shrink() is freeing buffers from the dispose list (filled with
buffers from lru list), there is a possibility to have xfs_buf_stale() racing
with it, and removing buffers from dispose list before xfs_buftarg_shrink() does
it.

This happens because xfs_buftarg_shrink() handle the dispose list without
locking and the test condition in xfs_buf_stale() checks for the buffer being in
*any* list:

if (!list_empty(&bp->b_lru))

If the buffer happens to be on dispose list, this causes the buffer counter of
lru list (btp->bt_lru_nr) to be decremented twice (once in xfs_buftarg_shrink()
and another in xfs_buf_stale()) causing a wrong account usage of the lru list.

This may cause xfs_buftarg_shrink() to return a wrong value to the memory
shrinker shrink_slab(), and such account error may also cause an underflowed
value to be returned; since the counter is lower than the current number of
items in the lru list, a decrement may happen when the counter is 0, causing
an underflow on the counter.

The fix uses a new flag field (and a new buffer flag) to serialize buffer
handling during the shrink process. The new flag field has been designed to use
btp->bt_lru_lock/unlock instead of xfs_buf_lock/unlock mechanism.

dchinner, sandeen, aquini and aris also deserve credits for this.

by reenabling IRQ before calling ->poll, but it seems more
problems are introduced after that patch:

http://marc.info/?l=linux-netdev&m=134563282530588&w=2

So it is safe to fix be2net driver code directly.

This patch reverts the offending commit and fixes be_poll() by
avoid disabling BH there, this is okay because be_poll()
can be called either by poll_napi() which already disables
IRQ, or by net_rx_action() which already disables BH.

51cd8e6ff2 mm, slab: lock the correct nodelist after reenabling irqs
cache_grow() can reenable irqs so the cpu (and node) can change, so ensure
that we take list_lock on the correct nodelist.

This fixes an issue with commit 072bb0aa5e ("mm: sl[au]b: add
knowledge of PFMEMALLOC reserve pages") where list_lock for the wrong
node was taken after growing the cache.

f54b350d89 drm/radeon: fix double free in radeon_gpu_reset
radeon_ring_restore is freeing the memory for the saved
ring data. We need to remember that, otherwise we try to
restore the ring data again on the next try. Additional
to that it shouldn't try the reset infinitely if we have
saved ring data.

4a2b6662c3 drm/radeon: force dma32 to fix regression rs4xx,rs6xx,rs740
It seems some of those IGP dislike non dma32 page despite what
documentation says. Fix regression since we allowed non dma32
pages. It seems it only affect some revision of those IGP chips
as we don't know which one just force dma32 for all of them.

0ceb996c9e drm/radeon: rework panel mode setup
Adjust the panel mode setup to match the behavior
of the vbios.  Rather than checking for specific
bridge chip ids, just check the eDP configuration register.
This saves extra aux transactions and works across
DP bridge chips without requiring additional per chip
id checking.

c205b232a6 drm/radeon/atom: powergating fixes for DCE6
Power gating is per crtc pair, but the powergating registers
should be called individually.  The hw handles power up/down
properly.  The pair is powered up if either crtc in the pair
is powered up and the pair is not powered down until both
crtcs in the pair are powered down.  This simplifies
programming and should save additional power as the previous
code never actually power gated the crtc pair.

8d1af57ae3 drm/radeon/atom: rework DIG modesetting on DCE3+
The ordering is important and the current drm code
wasn't cutting it for modern DIG encoders.  We need
to have information about crtc before setting up
the encoders so I've shifted the ordering a bit.
Probably we'll need a full rework akin to danvet's
recent intel patchs.  This patch fixes numerous
issues with DP bridge chips and makes link training
much more reliable.

523885dec1 drm/radeon: add proper checking of RESOLVE_BOX command for r600-r700
Checking of the second colorbuffer was skipped on r700, because
CB_TARGET_MASK was 0xf. With r600, CB_TARGET_MASK is changed to 0xff,
so we must set the number of samples of the second colorbuffer to 1 in order
to pass the CS checker.
The DRM version is bumped, because RESOLVE_BOX is always rejected without this
fix on r600.
