- The recent ACPICA commit that set the ACPI _REV return value to 2
(which is the value always used by Windows and now mandated by the
spec too) in order to prevent the firmware people from using it to
play tricks with us caused a serious audio regression to happen on
Dell XPS 13 (the AML on that machine uses the _REV return value to
decide how to expose audio to the OS and does that to hide the lack
of proper support for its I2S audio in Linux), so revert that
commit for now and we'll revisit the issue in the next cycle.
- Ensure that the ordering of acpi_reserve_resources() with respect
to the rest of the ACPI initialization sequence will always be the

registers may be assigned to a PCI host bridge as a result of a

mm, numa: really disable NUMA balancing by default on single node machines
NUMA balancing is meant to be disabled by default on UMA machines but
the check is using nr_node_ids (highest node) instead of
num_online_nodes (online nodes).
The consequences are that a UMA machine with a node ID of 1 or higher
will enable NUMA balancing. This will incur useless overhead due to
minor faults with the impact depending on the workload. These are the
impact on the stats when running a kernel build on a single node machine
whose node ID happened to be 1:

kernfs: do not account ino_ida allocations to memcg
root->ino_ida is used for kernfs inode number allocations. Since IDA has
a layered structure, different IDs can reside on the same layer, which
is currently accounted to some memory cgroup. The problem is that each
kmem cache of a memory cgroup has its own directory on sysfs (under
/sys/fs/kernel/<cache-name>/cgroup). If the inode number of such a
directory or any file in it gets allocated from a layer accounted to the
cgroup which the cache is created for, the cgroup will get pinned for
good, because one has to free all kmem allocations accounted to a cgroup
in order to release it and destroy all its kmem caches. That said we
must not account layers of ino_ida to any memory cgroup.
Since per net init operations may create new sysfs entries directly
(e.g. lo device) or indirectly (nf_conntrack creates a new kmem cache
per each namespace, which, in turn, creates new sysfs entries), an easy
way to reproduce this issue is by creating network namespace(s) from
inside a kmem-active memory cgroup.

gfp: add __GFP_NOACCOUNT
Not all kmem allocations should be accounted to memcg. The following
patch gives an example when accounting of a certain type of allocations to
memcg can effectively result in a memory leak. This patch adds the
__GFP_NOACCOUNT flag which if passed to kmalloc and friends will force the
allocation to go through the root cgroup. It will be used by the next
patch.
Note, since in case of kmemleak enabled each kmalloc implies yet another
allocation from the kmemleak_object cache, we add __GFP_NOACCOUNT to
gfp_kmemleak_mask.
Alternatively, we could introduce a per kmem cache flag disabling
accounting for all allocations of a particular kind, but (a) we would not
be able to bypass accounting for kmalloc then and (b) a kmem cache with
this flag set could not be merged with a kmem cache without this flag,
which would increase the number of global caches and therefore
fragmentation even if the memory cgroup controller is not used.
Despite its generic name, currently __GFP_NOACCOUNT disables accounting
only for kmem allocations while user page allocations are always charged.
To catch abusing of this flag, a warning is issued on an attempt of
passing it to mem_cgroup_try_charge.

firmware: dmi_scan: Fix ordering of product_uuid
In function dmi_present(), dmi_walk_early() calls dmi_table(), which
calls dmi_decode(), which ultimately calls dmi_save_uuid(). This last
function makes a decision based on the value of global variable
dmi_ver. The problem is that this variable is set right _after_
dmi_walk_early() returns. So dmi_save_uuid() always sees dmi_ver == 0
regardless of the actual version implemented.
This causes /sys/class/dmi/id/product_uuid to always use the old
ordering even on systems implementing DMI/SMBIOS 2.6 or later, which
should use the new ordering.
This is broken since kernel v3.8 for legacy DMI implementations and
since kernel v3.10 for SMBIOS 2 implementations. SMBIOS 3
implementations with the 64-bit entry point are not affected.
The first breakage does not matter much as in practice legacy DMI
implementations are always for versions older than 2.6, which is when
the UUID ordering changed. The second breakage is more problematic as
it affects the vast majority of x86 systems manufactured since 2009.

MIPS: fix FP mode selection in lieu of .MIPS.abiflags data
Commit
46490b572544 ("MIPS: kernel: elf: Improve the overall ABI and FPU
mode checks") reworked the ELF FP ABI mode selection logic, but when
CONFIG_MIPS_O32_FP64_SUPPORT is enabled it breaks the use of binaries
which have no PT_MIPS_ABIFLAGS program header & associated
.MIPS.abiflags section.
A default mode is selected based upon whether the ELF contains MIPS32 or
MIPS64 code, but that selection is made in arch_elf_pt_proc.
arch_elf_pt_proc only executes when a PT_MIPS_ABIFLAGS program header is
found. If one is not found then arch_elf_pt_proc is never called, and no
default overall_fp_mode value is selected. When arch_check_elf is
called, both abi0 & abi1 are MIPS_ABI_FP_UNKNOWN which leads to both
prog_req & interp_req being set to none_req. none_req matches none of
the conditions for mode selection at the end of arch_check_elf, so
overall_fp_mode is left untouched. Finally once mips_set_personality_fp
is called the BUG() in the default case is then hit & the kernel likely
panics.
Fix this by moving the selection of a default overall mode to the start
of arch_check_elf, which runs once per ELF executed regardless of
whether it has a PT_MIPS_ABIFLAGS program header.

iommu/arm-smmu: Fix sign-extension of upstream bus addresses at stage 1
Stage 1 translation is controlled by two sets of page tables (TTBR0 and
TTBR1) which grow up and down from zero respectively in the ARMv8
translation regime. For the SMMU, we only care about TTBR0 and, in the
case of a 48-bit virtual space, we expect to map virtual addresses 0x0
through to 0xffff_ffff_ffff.
Given that some masters may be incapable of emitting virtual addresses
targetting TTBR1 (e.g. because they sit on a 48-bit bus), the SMMU
architecture allows bit 47 to be sign-extended, halving the virtual
range of TTBR0 but allowing TTBR1 to be used. This is controlled by the
SEP field in TTBCR2.
The SMMU driver incorrectly enables this sign-extension feature, which
causes problems when userspace addresses are programmed into a master
device with the SMMU expecting to map the incoming transactions via
TTBR0; if the top bit of address is set, we will instead get a
translation fault since TTBR1 walks are disabled in the TTBCR.
This patch fixes the issue by disabling sign-extension of a fixed
virtual address bit and instead basing the behaviour on the upstream bus
size: the incoming address is zero extended unless the upstream bus is
only 49 bits wide, in which case bit 48 is used as the sign bit and is
replicated to the upper bits.

This patch is based on a patch from Deepak S <deepak.s@intel.com>
from another platform.
The patch fixes an issue introduced by:
commit
e7778be1eab918274f79603d7c17b3ec8be77386
drm/i915: Fix startup failure in LRC mode after recent init changes
The above patch added a call to init_context() to fix an issue introduced
by a previous patch. But, it then opened up a small timing window for the
batches being added by the init_context (basically setting up the context)
to complete before the interrupts have been turned on, thus hanging the
GPU.

bnx2x: limit fw delay in kdump to 5s after boot
Commit
12a8541d5c82 "bnx2x: Delay during kdump load" added a 5 seconds
delay to bnx2x's probe function in the kdump case to let the firmware
realize the old driver is gone.
The problem with the delay is that it is per-device, so if you have
several bnx2x NICs in NPAR mode, the delays can accumulate to minutes.
Fix it by adjusting the delay so that we do not wait more than
necessary, i.e. no more delaying after 5 seconds of kernel boot time.

ARM: net: delegate filter to kernel interpreter when imm_offset() return value can't fit into 12bits.
The ARM JIT code emits "ldr rX, [pc, #offset]" to access the literal
pool. #offset maximum value is 4095 and if the generated code is too
large, the #offset value can overflow and not point to the expected
slot in the literal pool. Additionally, when overflow occurs, bits of
the overflow can end up changing the destination register of the ldr
instruction.
Fix that by detecting the overflow in imm_offset() and setting a flag
that is checked for each BPF instructions converted in
build_body(). As of now it can only be detected in the second pass. As
a result the second build_body() call can now fail, so add the
corresponding cleanup code in that case.
Using multiple literal pools in the JITed code is going to require
lots of intrusive changes to the JIT code (which would better be done
as a feature instead of fix), just delegating to the kernel BPF
interpreter in that case is a more straight forward, minimal fix and
easy to backport.

drm: Zero out invalid vblank timestamp in drm_update_vblank_count.
Since commit
844b03f27739135fe1fed2fef06da0ffc4c7a081 we make
sure that after vblank irq off, we return the last valid
(vblank count, vblank timestamp) pair to clients, e.g., during
modesets, which is good.
An overlooked side effect of that commit for kms drivers without
support for precise vblank timestamping is that at vblank irq
enable, when we update the vblank counter from the hw counter, we
can't update the corresponding vblank timestamp, so now we have a
totally mismatched timestamp for the new count to confuse clients.
Restore old client visible behaviour from before Linux 3.17, but
zero out the timestamp at vblank counter update (instead of disable
as in original implementation) if we can't generate a meaningful
timestamp immediately for the new vblank counter. This will fix
this regression, so callers know they need to retry again later
if they need a valid timestamp, but at the same time preserves
the improvements made in the commit mentioned above.

net/rds: RDS-TCP robustness fixes
This patch-set contains bug fixes for state-recovery at the RDS
layer when the underlying transport is TCP and the TCP state at one
of the endpoints is reset
V2 changes: DaveM comments to reduce memory footprint, follow
NFS/RPC model where possible. Added test-case #3
Without the changes in this set, when one of the endpoints is reset,
the existing code does not correctly clean up RDS socket state for stale
connections, resulting in some unstable, timing-dependant behavior on
the wire, including an infinite exchange of 3WHs back-and-forth, and a
resulting potential to never converge RDS state.
Test cases used to verify the changes in this set are:
1. Start rds client/server applications on two participating nodes,
node1 and node2. After at least one packet has been sent (to establish
the TCP connection), restart the rds_tcp module on the client, and
now resend packets. Tcpdump should show server sending a FIN for the
"old" client port, and clean connection establishment/exchange for
the new client port.
2. At the end of step 1, restart rds srever on node2, and start client on
node1, make sure using tcpdump, 'netstat -an|grep 16385' that
packets flow correctly.
3. start RDS client/server application on two participating nodes, and
repeat steps 1 and 2, but this time, simulate node failure by doing
"ifconfig <intf> down", so no FIN is sent.

net/rds: RDS-TCP: Always create a new rds_sock for an incoming connection.
When running RDS over TCP, the active (client) side connects to the
listening ("passive") side at the RDS_TCP_PORT. After the connection
is established, if the client side reboots (potentially without even
sending a FIN) the server still has a TCP socket in the esablished
state. If the server-side now gets a new SYN comes from the client
with a different client port, TCP will create a new socket-pair, but
the RDS layer will incorrectly pull up the old rds_connection (which
is still associated with the stale t_sock and RDS socket state).
This patch corrects this behavior by having rds_tcp_accept_one()
always create a new connection for an incoming TCP SYN.
The rds and tcp state associated with the old socket-pair is cleaned
up via the rds_tcp_state_change() callback which would typically be
invoked in most cases when the client-TCP sends a FIN on TCP restart,
triggering a transition to CLOSE_WAIT state. In the rarer event of client
death without a FIN, TCP_KEEPALIVE probes on the socket will detect
the stale socket, and the TCP transition to CLOSE state will trigger
the RDS state cleanup.

host gets -ENETUNREACH on e.g. connect() because ip6_dst_lookup_tail
calls ip6_route_output first, and given source address any, it fails,
and ip6_route_get_saddr is never called.
The change is to use the ip6_route_get_saddr, even if the initial
ip6_route_output fails, and then doing ip6_route_output _again_ after
we have appropriate source address available.
Note that this is '99% fix' to the problem; a correct fix would be to
do route lookups only within addrconf.c when picking a source address,
and never call ip6_route_output before source address has been
populated.

namei: d_is_negative() should be checked before ->d_seq validation
Fetching ->d_inode, verifying ->d_seq and finding d_is_negative() to
be true does *not* mean that inode we'd fetched had been NULL - that
holds only while ->d_seq is still unchanged.
Shift d_is_negative() checks into lookup_fast() prior to ->d_seq
verification.
