ASoC: Intel: Common: Update dsp register poll implementation
Poll implementation is not quite accurate, especially for smaller
values of timeout or timeout values close to the actual timeout needed
Use jiffies to set the timeout value and time_before() to get the
accurate time. So update the dsp register poll implementation to
provide accurate timeout using jiffies.

MIPS: Return -ENODEV from weak implementation of rtc_mips_set_time
The sync_cmos_clock function in kernel/time/ntp.c first tries to update
the internal clock of the cpu by calling the "update_persistent_clock64"
architecture specific function. If this returns -ENODEV, it then tries
to update an external RTC using "rtc_set_ntp_time".
On the mips architecture, the weak implementation of the underlying
function would return 0 if it wasn't overridden. This meant that the
sync_cmos_clock function would never try to update an external RTC
(if both CONFIG_GENERIC_CMOS_UPDATE and CONFIG_RTC_SYSTOHC are
configured)
Returning -ENODEV instead, means that an external RTC will be tried.

ibmveth: set correct gso_size and gso_type
This patch is based on an earlier one submitted
by Jon Maxwell with the following commit message:
"We recently encountered a bug where a few customers using ibmveth on the
same LPAR hit an issue where a TCP session hung when large receive was
enabled. Closer analysis revealed that the session was stuck because the
one side was advertising a zero window repeatedly.
We narrowed this down to the fact the ibmveth driver did not set gso_size
which is translated by TCP into the MSS later up the stack. The MSS is
used to calculate the TCP window size and as that was abnormally large,
it was calculating a zero window, even although the sockets receive buffer
was completely empty."
We rely on the Virtual I/O Server partition in a pseries
environment to provide the MSS through the TCP header checksum
field. The stipulation is that users should not disable checksum
offloading if rx packet aggregation is enabled through VIOS.
Some firmware offerings provide the MSS in the RX buffer.
This is signalled by a bit in the RX queue descriptor.

"Several fixes to the DSM (ACPI device specific method) marshaling

I consider these urgent enough to send for 4.9 consideration since
they fix the kernel's handling of ARS (Address Range Scrub) commands.
Especially for platforms without machine-check-recovery capabilities,
successful execution of ARS commands enables the platform to
potentially break out of an infinite reboot problem if a media error
is present in the boot path. There is also a one line fix for a
device-dax read-only mapping regression.

325896ffdf90 ("device-dax: fix private mapping

Commit
efda1b5d87cb ("acpi, nfit, libnvdimm: fix / harden ars_status

results, this never would have worked in the past, but we only just
recently discovered a BIOS implementation that emits this arguably
spec non-compliant result.
The remaining two commits are additional fall out from thinking
through the implications of a zero / truncated length result of the
ARS Status command.
In order to mitigate the risk that these changes introduce yet more
regressions they are backstopped by a new unit test in commit

parisc: Fix TLB related boot crash on SMP machines
At bootup we run measurements to calculate the best threshold for when we
should be using full TLB flushes instead of just flushing a specific amount of
TLB entries. This performance test is run over the kernel text segment.
But running this TLB performance test on the kernel text segment turned out to
crash some SMP machines when the kernel text pages were mapped as huge pages.
To avoid those crashes this patch simply skips this test on some SMP machines
and calculates an optimal threshold based on the maximum number of available
TLB entries and number of online CPUs.
On a technical side, this seems to happen:
The TLB measurement code uses flush_tlb_kernel_range() to flush specific TLB
entries with a page size of 4k (pdtlb 0(sr1,addr)). On UP systems this purge
instruction seems to work without problems even if the pages were mapped as
huge pages. But on SMP systems the TLB purge instruction is broadcasted to
other CPUs. Those CPUs then crash the machine because the page size is not as
expected. C8000 machines with PA8800/PA8900 CPUs were not affected by this
problem, because the required cache coherency prohibits to use huge pages at
all. Sadly I didn't found any documentation about this behaviour, so this
finding is purely based on testing with phyiscal SMP machines (A500-44 and
J5000, both were 2-way boxes).

ceph: don't set req->r_locked_dir in ceph_d_revalidate
This function sets req->r_locked_dir which is supposed to indicate to
ceph_fill_trace that the parent's i_rwsem is locked for write.
Unfortunately, there is no guarantee that the dir will be locked when
d_revalidate is called, so we really don't want ceph_fill_trace to do
any dcache manipulation from this context. Clear req->r_locked_dir since
it's clearly not safe to do that.
What we really want to know with d_revalidate is whether the dentry
still points to the same inode. ceph_fill_trace installs a pointer to
the inode in req->r_target_inode, so we can just compare that to
d_inode(dentry) to see if it's the same one after the lookup.
Also, since we aren't generally interested in the parent here, we can
switch to using a GETATTR to hint that to the MDS, which also means that
we only need to reserve one cap.
Finally, just remove the d_unhashed check. That's really outside the
purview of a filesystem's d_revalidate. If the thing became unhashed
while we're checking it, then that's up to the VFS to handle anyway.

libata-scsi: disable SCT Write Same for the moment
SCT Write Same support had been introduced with
commit
7b2030942859 ("libata: Add support for SCT Write Same")
Some problems, namely excessive userspace segfaults, had been reported at
http://lkml.kernel.org/r/
20160908192736.GA4356@gmail.com
This lead to commit
0ce1b18c42a5 ("libata: Some drives failing on
SCT Write Same") which strived to disable SCT Write Same on !ZAC devices.
Due to the way this was done and to the logic in sd_config_write_same(),
this didn't work for those devices that have
->max_ws_blocks > SD_MAX_WS10_BLOCKS: for these, ->no_write_same and
->max_write_same_sectors would still be non-zero,
but ->ws10 == ->ws16 == 0. This would cause sd_setup_write_same_cmnd() to
demultiplex REQ_OP_WRITE_SAME requests to WRITE_SAME, and these in turn
aren't supported by libata-scsi:
EXT4-fs (dm-1): Delayed block allocation failed for inode
2625094 at
logical offset 2032 with max blocks 2 with error 121
EXT4-fs (dm-1): This should not happen!! Data will be lost
121 == EREMOTEIO is what scsi_io_completion() asserts in case of
invalid opcodes.
Back to the original problem of userspace segfaults: this can be tracked
down to ata_format_sct_write_same() overwriting the input page. Sometimes,
this page is ZERO_PAGE(0) which ceases to be filled with zeros from that
point on. Since ZERO_PAGE(0) is used for userspace .bss mappings, code of
the following is doomed:
static char *a = NULL; /* .bss */
...
if (a)
*a = 'a';
This problem is not solved by disabling SCT Write Same for !ZAC devices
only.
It can certainly be fixed, but the final release is quite close -- so
disable SCT Write Same for all ATA devices rather than introducing some
SCT key buffer allocation schemes at this point.

ARM: dts: imx7d: fix LCDIF clock assignment

Clock Clock Root Description

pix_clk LCDIF_PIXEL_CLK_ROOT Pixel clock
ipg_clk_s MAIN_AXI_CLK_ROOT Peripheral access clock
All of them are switched by a single gate, which is part of the
IMX7D_LCDIF_PIXEL_ROOT_CLK clock. Hence using that clock also for
the AXI bus clock (clock-name "axi") makes sure the gate gets

There seem to be no separate AXI display clock, and the clock is
optional. Hence remove the dummy clock.

phy: Don't increment MDIO bus refcount unless it's a different owner
Commit
3e3aaf649416 ("phy: fix mdiobus module safety") fixed the way we
dealt with MDIO bus module reference count, but sort of introduced a
regression in that, if an Ethernet driver registers its own MDIO bus
driver, as is common, we will end up with the Ethernet driver's
module->refnct set to 1, thus preventing this driver from any removal.
Fix this by comparing the network device's device driver owner against
the MDIO bus driver owner, and only if they are different, increment the
MDIO bus module refcount.

Revert "default exported asm symbols to zero"
This reverts commit
8ab2ae655bfe384335c5b6b0d6041e0ddce26b00.
I loved that commit because of how it explained what the problem with
newer versions of binutils were, but the actual patch itself turns out
to not work very well.
It has two problems:
- a zero CRC value isn't actually right. It happens to work for the
case where both sides of the equation fail at giving the symbol a
crc, but there are cases where the users of the exported symbol get
the right crc (due to seeing the C declarations), but the actual
exporting itself does not (due to the whole weak asm symbol issue).
So then the module load fails after all - we did have a crc for the
symbol, but we couldn't match it with the loaded module.
- it seems that the alpha assembler has special semantics for the
'.set' directive, and on alpha it doesn't actually set the value of
the specified symbol at all, it is instead used to set various
assembly modes (eg ".set noat" and ".set noreorder").
So using ".set" to set the symbol value would just cause build
failures on alpha.
I'm sure we'll find some other workaround for these issues (hopefully
that involves getting rid of modversions entirely some day, but people
are also talking about just using smarter tools). But for now we'll
just fall back on commit
faaae2a58143 ("Re-enable CONFIG_MODVERSIONS in
a slightly weaker form") that just let's a missing crc through.

crypto: mcryptd - Check mcryptd algorithm compatibility
Algorithms not compatible with mcryptd could be spawned by mcryptd
with a direct crypto_alloc_tfm invocation using a "mcryptd(alg)" name
construct. This causes mcryptd to crash the kernel if an arbitrary
"alg" is incompatible and not intended to be used with mcryptd. It is
an issue if AF_ALG tries to spawn mcryptd(alg) to expose it externally.
But such algorithms must be used internally and not be exposed.
We added a check to enforce that only internal algorithms are allowed
with mcryptd at the time mcryptd is spawning an algorithm.

crypto: algif_aead - fix AEAD tag memory handling
For encryption, the AEAD ciphers require AAD || PT as input and generate
AAD || CT || Tag as output and vice versa for decryption. Prior to this
patch, the AF_ALG interface for AEAD ciphers requires the buffer to be
present as input for encryption. Similarly, the output buffer for
decryption required the presence of the tag buffer too. This implies
that the kernel reads / writes data buffers from/to kernel space
even though this operation is not required.
This patch changes the AF_ALG AEAD interface to be consistent with the
in-kernel AEAD cipher requirements.
Due to this handling, he changes are transparent to user space with one
exception: the return code of recv indicates the mount of output buffer.
That output buffer has a different size compared to before the patch
which implies that the return code of recv will also be different.
For example, a decryption operation uses 16 bytes AAD, 16 bytes CT and
16 bytes tag, the AF_ALG AEAD interface before showed a recv return
code of 48 (bytes) whereas after this patch, the return code is 32
since the tag is not returned any more.
