As far back as I can see (which right now is a draft of the v1.2 spec
dating from September 2008), bits 24-31 of the Extended Capability Register
have already been reserved. I have no idea why anyone ever thought there
would be multiple sets of IOTLB registers, but we've never supported them
and all we do is make sure we map enough MMIO space for them.
Kill it dead. Those bits do actually have a different meaning now.

The acpi_os_ioremap() function may be used to map normal RAM or IO
regions. The current implementation simply uses ioremap_cache(). This
will work for some architectures, but arm64 ioremap_cache() cannot be
used to map IO regions which don't support caching. So for arm64, use
ioremap() for non-RAM regions.

rhashtable_destroy() variant which stops rehashes, iterates over
the table and calls a callback to release resources.
Avoids need for nft_hash to embed rhashtable internals and allows to
get rid of the being_destroyed flag. It also saves a 2nd mutex
lock upon destruction.
Also fixes an RCU lockdep splash on nft set destruction due to
calling rht_for_each_entry_safe() without holding bucket locks.
Open code this loop as we need know that no mutations may occur in

sata_sil24 for some reason pukes when tags are allocated round-robin
which helps tag ordered controllers. To work around the issue,
72dd299d50 ("libata: allow sata_sil24 to opt-out of tag ordered
submission") introduced ATA_FLAG_LOWTAG which tells libata tag
allocation to do lowest-first.
However, with the recent switch to blk-mq tag allocation, the liata
tag allocation code path is no longer used and the workaround is now
implemented in the block layer and selected by setting
scsi_host_template->tag_alloc_policy to BLK_TAG_ALLOC_FIFO. See
9269e23496 ("libata: make sata_sil24 use fifo tag allocator").
This leaves ATA_FLAG_LOWTAG withoout any actual user. Remove it.

The current state of the different cpuidle drivers is the different PM
operations are passed via the platform_data using the platform driver
paradigm.
This approach allowed to split the low level PM code from the arch specific
and the generic cpuidle code.
Unfortunately there are complaints about this approach as, in the context of the
single kernel image, we have multiple drivers loaded in memory for nothing and
the platform driver is not adequate for cpuidle.
This patch provides a common interface via cpuidle ops for all new cpuidle
driver and a definition for the device tree.
It will allow with the next patches to a have a common definition with ARM64
and share the same cpuidle driver.
The code is optimized to use the __init section intensively in order to reduce
the memory footprint after the driver is initialized and unify the function
names with ARM64.

The commit 963ecbd41a ("rhashtable:
Fix use-after-free in rhashtable_walk_stop") fixed a real bug
but created another one because we may end up sleeping inside an
RCU critical section.
This patch fixes it properly by replacing the mutex with a spin
lock that specifically protects the walker lists.

If a DAD conflict is detected, we want to retry privacy stable address
generation up to idgen_retries (= 3) times with a delay of idgen_delay
(= 1 second). Add the logic to addrconf_dad_failure.
By design, we don't clean up dad failed permanent addresses.

This patch implements the stable privacy address generation for
link-local and autoconf addresses as specified in RFC7217.
RID = F(Prefix, Net_Iface, Network_ID, DAD_Counter, secret_key)
is the RID (random identifier). As the hash function F we chose one
round of sha1. Prefix will be either the link-local prefix or the
router advertised one. As Net_Iface we use the MAC address of the
device. DAD_Counter and secret_key are implemented as specified.
We don't use Network_ID, as it couples the code too closely to other
subsystems. It is specified as optional in the RFC.
As Net_Iface we only use the MAC address: we simply have no stable
identifier in the kernel we could possibly use: because this code might
run very early, we cannot depend on names, as they might be changed by
user space early on during the boot process.
A new address generation mode is introduced,
IN6_ADDR_GEN_MODE_STABLE_PRIVACY. With iproute2 one can switch back to
none or eui64 address configuration mode although the stable_secret is
already set.
We refuse writes to ipv6/conf/all/stable_secret but only allow
ipv6/conf/default/stable_secret and the interface specific file to be
written to. The default stable_secret is used as the parameter for the
namespace, the interface specific can overwrite the secret, e.g. when
switching a network configuration from one system to another while
inheriting the secret.

This patch implements the procfs logic for the stable_address knob:
The secret is formatted as an ipv6 address and will be stored per
interface and per namespace. We track initialized flag and return EIO
errors until the secret is set.
We don't inherit the secret to newly created namespaces.

This patch reintroduces immediate rehash during insertion. If
we find during insertion that the table is full or the chain
length exceeds a set limit (currently 16 but may be disabled
with insecure_elasticity) then we will force an immediate rehash.
The rehash will contain an expansion if the table utilisation
exceeds 75%.
If this rehash fails then the insertion will fail. Otherwise the
insertion will be reattempted in the new hash table.

This patch adds the missing bits to allow multiple rehashes. The
read-side as well as remove already handle this correctly. So it's
only the rehasher and insertion that need modification to handle
this.
Note that this patch doesn't actually enable it so for now rehashing
is still only performed by the worker thread.
This patch also disables the explicit expand/shrink interface because
the table is meant to expand and shrink automatically, and continuing
to export these interfaces unnecessarily complicates the life of the
rehasher since the rehash process is now composed of two parts.

Since every current rhashtable user uses jhash as their hash
function, the fact that jhash is an inline function causes each
user to generate a copy of its code.
This function provides a solution to this problem by allowing
hashfn to be unset. In which case rhashtable will automatically
set it to jhash. Furthermore, if the key length is a multiple
of 4, we will switch over to jhash2.

When rht_key_hashfn is called from rhashtable itself and params
is equal to ht->p, there is no point in checking params.key_len
and falling back to ht->p.key_len.
For some reason gcc couldn't figure out that params is the same
as ht->p. So let's help it by only checking params.key_len when
it's a constant.

====================
pull-request: can-next 2015-03-23
this is a pull request of 6 patches for net-next/master.
A patch by Florian Westphal, converts the skb->destructor to use
sock_efree() instead of own destructor. Ahmed S. Darwish's patch
converts the kvaser_usb driver to use unregister_candev(). A patch by
me removes a return from a void function in the m_can driver. Yegor
Yefremov contributes a patch for combined rx/tx LED trigger support. A
sparse warning in the esd_usb2 driver was fixes by Thomas Körper. Ben
Dooks converts the at91_can driver to use endian agnostic IO accessors.

====================
Netfilter updates for net-next
The following patchset contains Netfilter updates for net-next.
Basically, more incremental updates for br_netfilter from Florian
Westphal, small nf_tables updates (including one fix for rb-tree
locking) and small two-liner to add extra validation for the REJECT6
target.
More specifically, they are:
1) Use the conntrack status flags from br_netfilter to know that DNAT is
happening. Patch for Florian Westphal.
2) nf_bridge->physoutdev == NULL already indicates that the traffic is
bridged, so let's get rid of the BRNF_BRIDGED flag. Also from Florian.
3) Another patch to prepare voidization of seq_printf/seq_puts/seq_putc,
from Joe Perches.
4) Consolidation of nf_tables_newtable() error path.
5) Kill nf_bridge_pad used by br_netfilter from ip_fragment(),
from Florian Westphal.
6) Access rb-tree root node inside the lock and remove unnecessary
locking from the get path (we already hold nfnl_lock there), from
Patrick McHardy.
7) You cannot use a NFT_SET_ELEM_INTERVAL_END when the set doesn't
support interval, also from Patrick.
8) Enforce IP6T_F_PROTO from ip6t_REJECT to make sure the core is
actually restricting matches to TCP.

The last patch reduced our interrupt-suppression region to one address,
so simplify the code somewhat.
Also, remove the obsolete undefined instruction ranges and the comment
which refers to lguest_guest.S instead of head_32.S.
