Checkpatch is really quite bad for user code like this, but it

git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi into core/efi
Pull v4.4 EFI updates from Matt Fleming:
- Make the EFI System Resource Table (ESRT) driver explicitly
non-modular by ripping out the module_* code since Kconfig doesn't
allow it to be built as a module anyway. (Paul Gortmaker)
- Make the x86 efi=debug kernel parameter, which enables EFI debug
code and output, generic and usable by arm64. (Leif Lindholm)
- Add support to the x86 EFI boot stub for 64-bit Graphics Output
Protocol frame buffer addresses. (Matt Fleming)
- Detect when the UEFI v2.5 EFI_PROPERTIES_TABLE feature is enabled
in the firmware and set an efi.flags bit so the kernel knows when
it can apply more strict runtime mapping attributes - Ard Biesheuvel
- Auto-load the efi-pstore module on EFI systems, just like we
currently do for the efivars module. (Ben Hutchings)
- Add "efi_fake_mem" kernel parameter which allows the system's EFI
memory map to be updated with additional attributes for specific
memory ranges. This is useful for testing the kernel code that handles
the EFI_MEMORY_MORE_RELIABLE memmap bit even if your firmware
doesn't include support. (Taku Izumi)
Note: there is a semantic conflict between the following two commits:
8a53554e12e9 ("x86/efi: Fix multiple GOP device support")
ae2ee627dc87 ("efifb: Add support for 64-bit frame buffer addresses")
I fixed up the interaction in the merge commit, changing the type of
current_fb_base from u32 to u64.

In order to get into 64-bit protected mode, you need to enable
paging while EFER.LMA=1. For this to work, CS.L must be 0.
Currently, we load the segments before CR0 and CR4, which means
that if RSM returns into 64-bit protected mode CS.L is already 1
and everything breaks.
Luckily, CS.L=0 is always the case when executing RSM, because it
is forbidden to execute RSM from 64-bit protected mode. Hence it
is enough to load CR0 and CR4 first, and only then the segments.

On sparc, we see unaligned access messages on each modprobe[-r]:
Kernel unaligned access at TPC[6ad9b4] pkcs7_verify [..]
Kernel unaligned access at TPC[6a5484] crypto_shash_finup [..]
Kernel unaligned access at TPC[6a5390] crypto_shash_update [..]
Kernel unaligned access at TPC[10150308] sha1_sparc64_update [..]
Kernel unaligned access at TPC[101501ac] __sha1_sparc64_update [..]
These ware triggered by mod_verify_sig() invocations of pkcs_verify(), and
are are being caused by an unaligned desc at (sha1, digest_size is 0x14)
desc = digest + digest_size;
To fix this, pkcs7_verify needs to make sure that desc is pointing
at an aligned value past the digest_size, and kzalloc appropriately,
taking alignment values into consideration.

The mxs-dcp driver relies on the stmp_reset_block() helper function, which
is provided by CONFIG_STMP_DEVICE. This symbol is always set on MXS,
but the driver can now also be built for MXC (i.MX6), which results
in a built error if no other driver selects STMP_DEVICE:
drivers/built-in.o: In function `mxs_dcp_probe':
vf610-ocotp.c:(.text+0x3df302): undefined reference to `stmp_reset_block'

As all the import functions and export functions are virtually
identical, factor out their common parts into a generic
mv_cesa_ahash_import() and mv_cesa_ahash_export() respectively. This
performs the actual import or export, and we pass the data pointers and
length into these functions.
We have to switch a % const operation to do_div() in the common import
function to avoid provoking gcc to use the expensive 64-bit by 64-bit
modulus operation.

Attempting to use the sha1 digest for openssh via openssl reveals that
the result from the hash is wrong: this happens when we export the
state from one socket and import it into another via calling accept().
The reason for this is because the operation is reset to "initial block"
state, whereas we may be past the first fragment of data to be hashed.
Arrange for the operation code to avoid the initialisation of the state,
thereby preserving the imported state.

When a AF_ALG fd is accepted a second time (hence hash_accept() is
used), hash_accept_parent() allocates a new private context using
sock_kmalloc(). This context is uninitialised. After use of the new
fd, we eventually end up with the kernel complaining:
marvell-cesa f1090000.crypto: dma_pool_free cesa_padding, c0627770/0 (bad dma)
where c0627770 is a random address. Poisoning the memory allocated by
the above sock_kmalloc() produces kernel oopses within the marvell hash
code, particularly the interrupt handling.
The following simplfied call sequence occurs:
hash_accept()
crypto_ahash_export()
marvell hash export function
af_alg_accept()
hash_accept_parent() <== allocates uninitialised struct hash_ctx
crypto_ahash_import()
marvell hash import function
hash_ctx contains the struct mv_cesa_ahash_req in its req.__ctx member,
and, as the marvell hash import function only partially initialises
this structure, we end up with a lot of members which are left with
whatever data was in memory prior to sock_kmalloc().
Add zero-initialisation of this structure.

Several of the algorithms in marvell/hash.c have a statesize of zero.
When an AF_ALG accept() on an already-accepted file descriptor to
calls into hash_accept(), this causes:
char state[crypto_ahash_statesize(crypto_ahash_reqtfm(req))];
to be zero-sized, but we still pass this to:
err = crypto_ahash_export(req, state);
which proceeds to write to 'state' as if it was a "struct md5_state",
"struct sha1_state" etc. Add the necessary initialisers for the
.statesize member.

When multiple GOP devices exists, but none of them implements
ConOut, the code should just choose the first GOP (according to
the comments). But currently 'fb_base' will refer to the last GOP,
while other parameters to the first GOP, which will likely
result in a garbled display.
I can reliably reproduce this bug using my ASRock Z87M Extreme4
motherboard with CSM and integrated GPU disabled, and two PCIe
video cards (NVidia GT640 and GTX980), booting from efi-stub
(booting from grub works fine). On the primary display the
ASRock logo remains and on the secondary screen it is garbled
up completely.

In commit 6e498158a827 ("tipc: move link synch and failover to link aggregation level")
we introduced a new mechanism for performing link failover and
synchronization. We have now detected a bug in this mechanism.
During link synchronization we use the arrival of any packet on
the tunnel link to trig a check for whether it has reached the
synchronization point or not. This has turned out to be too
permissive, since it may cause an arriving non-last SYNCH packet to
end the synch state, just to see the next SYNCH packet initiate a
new synch state with a new, higher synch point. This is not fatal,
but should be avoided, because it may significantly extend the
synchronization period, while at the same time we are not allowed
to send NACKs if packets are lost. In the worst case, a low-traffic
user may see its traffic stall until a LINK_PROTOCOL state message
trigs the link to leave synchronization state.
At the same time, LINK_PROTOCOL packets which happen to have a (non-
valid) sequence number lower than the tunnel link's rcv_nxt value will
be consistently dropped, and will never be able to resolve the situation
described above.
We fix this by exempting LINK_PROTOCOL packets from the sequence number
check, as they should be. We also reduce (but don't completely
eliminate) the risk of entering multiple synchronization states by only
allowing the (logically) first SYNCH packet to initiate a synchronization
state. This works independently of actual packet arrival order.

Revert the commit e2ca690b657f ("ipv4/icmp: redirect messages
can use the ingress daddr as source"), which tried to introduce a more
suitable behaviour for ICMP redirect messages generated by VRRP routers.
However RFC 5798 section 8.1.1 states:
The IPv4 source address of an ICMP redirect should be the address
that the end-host used when making its next-hop routing decision.
while said commit used the generating packet destination
address, which do not match the above and in most cases leads to
no redirect packets to be generated.

Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates 2015-10-13
This series contains updates to i40e, i40evf, ixgbe and fm10k.
Carolyn cleans up ndo_bridge_getlink() by flagging a parameter as
__always_unused, since it is never used. Adds a member to the nvm_info
struct to store OEM version info to be output either by OID or ethtool.
Neerav cleans up a remaining bit shift to use BIT() macro.
Mitch fixes the i40evf driver to properly handle calls to its
ndo_set_mac_address() method. It did not properly check to see if the
override would be allowed by the PF driver, and it never removed the old
address from its filter list. Cleaned up the use of
i40e_enable_vf_mappings() in i40e_alloc_vfs(), since it is just redundant
since we already call it by i40e_reset_vf(). Fixed a possible panic
in some circumstances where the firmware may fail to allocate a VSI for
a VF by checking the return value from i40e_alloc_vf_res() and don't
try to configure the device further if it failed.
Greg fixes the parsing of CEE App TLVs so the caller does not have to
consider whether the App came from a CEE or IEEE DCBx negotiation.
Shannon moves the device ids into a standalone file due to the desire
to write user-land drivers (and other requests) without needing the rest
of the include files.
Catherine adds the ability to save the module information from
get_phy_capabilities() to be used to determine which speeds the module
supports. Also cleaned up the PHY structure by removing unused members
and add the ability to store the PHY capabilities reported by the
firmware.
Emil modifies ixgbe to ensure that flow control packets initiated by the
VF are dropped and reported as spoofed.
Jacob cleans up the fm10k driver to avoid buffer overflow by using
sprintf(), so convert to using snprintf(). Also fixed the use of an
enum as a boolean, so check for the actual value of NETREG_UNINITIALIZED
in case it ever changes from the current value of zero.
v2: Dropped patch 11 of the original series, which added functions that
were never used.

Using the same values in ath9k results in much better throughput for me.
Before this patch I had a huge amount of packet loss (sometimes up to

My device uses a AR9227 which is the PCI variant of the AR9287.

moved also the plane state readout to intel_sanitize_crtc() which isn't
quite right in my opinion.

The dotclock is often calculated in encoder .get_config(), so we
shouldn't copy the adjusted_mode to hwmode until we have read out the
dotclock.
Gets rid of some warnings like these:
[drm:drm_calc_timestamping_constants [drm]] *ERROR* crtc 21: Can't calculate constants, dotclock = 0!
[drm:i915_get_vblank_timestamp] crtc 0 is disabled
v2: Steal Maarten's idea to move crtc->mode etc. assignment too

This reverts commit 721a09f7393de6c28a07516dccd654c6e995944a.
There is nothing wrong with the commit per se. We had two versions of
the commit, one in -next headed for v4.4 and this one for v4.3. Turns
out we'll need to backport more fixes from -next, and they conflict with
the v4.3 version. It gets messy. It will be easiest to revert this one,
and backport all the relevant commits from -next without modifications;
they apply cleanly after this revert.

Now that a new mac80211-based driver for Realtek devices has been submitted,
it is time to reorganize the directories. Rather than having directories
rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in
drivers/net/wireless/realtek/. This change simplifies the directory
structure, but does not result in any configuration changes that are
visable to the user.

Freescale iMX23/iMX28 and Alphascale ASM9260 have similar interrupt
collectors. We already prepared the mxs driver to handle a different
register layout. Add the actual ASM9260 support.
Differences between these devices:
- Different register offsets
- Different count of interupt lines per register
- ASM9260 does not provide reset bit
- ASM9260 does not support FIQ.

Alphascale asm9260 has similar functionality but different register
offsets. To support asm9260 in the mxs driver we need to rework the
hardcoded access mechanisms.
- Define SET_REG and CLR_REG. These controllers support seperate CLR and
SET offsets for each register.
- Reimplement HW_ICOLL_INTERRUPT with SET_REG and CLR_REG to make it
usable for both cases.
- Instead of using icoll_base and adding the offsets at runtime,
create a new data structure which contains base pointers to all
required regitsters and use it.
- Split out functionality, which is required for the init code of mxs
and asm9260, into helper functions

Current code will only warn and then dereference the NULL pointer or
continue, which results in a fatal NULL pointer dereference later.
If the initialization fails, the machine is unusable, so panic right
away.

next patch]
