Lift stac/clac pairs from __futex_atomic_op{1,2} into arch_futex_atomic_op_inuser(),
fold them with access_ok() in there. The switch in arch_futex_atomic_op_inuser()

it's not really different from e.g. __sanitizer_cov_trace_cmp4();

Move access_ok() in and pagefault_enable()/pagefault_disable() out.
Mechanical conversion only - some instances don't really need
a separate access_ok() at all (e.g. the ones only using
get_user()/put_user(), or architectures where access_ok()
is always true); we'll deal with that in followups.

pull-request: bpf 2020-03-27
The following pull-request contains BPF updates for your *net* tree.
We've added 3 non-merge commits during the last 4 day(s) which contain
a total of 4 files changed, 25 insertions(+), 20 deletions(-).
The main changes are:
1) Explicitly memset the bpf_attr structure on bpf() syscall to avoid
having to rely on compiler to do so. Issues have been noticed on
some compilers with padding and other oddities where the request was
then unexpectedly rejected, from Greg Kroah-Hartman.
2) Sanitize the bpf_struct_ops TCP congestion control name in order to
avoid problematic characters such as whitespaces, from Martin KaFai Lau.

On Android/x86 the module loading infrastructure can't deal with
softdeps. Therefore the check for presence of the Realtek PHY driver
module fails. mdiobus_register() will try to load the PHY driver
module, therefore move the check to after this call and explicitly
check that a dedicated PHY driver is bound to the PHY device.

For the devicetree files, there are a total of 20 patches, almost
entirely for 32-bit machines:
- The Allwinner/sun9i r40 SoC dtsi file contains a number of issues,
both for correctness and for style that are addressed in separate
patches. This causes most of the changed lines of the DT updates
this time.
- More Allwinner updates fixing the identification of the security
system on sun8i/A33, a recent regression of the A83t ethernet, and a
few board specific issues on the TBS-A711 macine.
- Several bug fixes for OMAP dts files, most notably fixing the timings
for the NAND flash on the Nokia N900 that regressed a while ago after
the move to configuring them from DT. Some other OMAPs now set the
correct dma limits on the L3 bus, and a regression fix addresses lost
Ethernet on dm814x
- One incorrect setting in the newly added Raspberry Pi Zero W that
may cause issues with the SD card controller.
- A missing property on the bcm2835 firmware node caused incorrect
DMA settings.
- An old bug on the oxnas platform causing spurious interrupts is
finally addressed.
- A regression on the Exynos Midas board broke the OLED panel
power supply.
- The i.MX6 phycore SoM specified the wrong voltage for the SoC,
this is now set to the values from the datasheet.
- Some 64-bit machines use a deprecated string to identify the PSCI
firmware.
There are also several small code fixes addressing mostly serious
issues:
- Fix the sunxi rsb bus access to no longer return incorrect data when
mixing 8 and 16 bit I/O.
- Fix a suspend/resume regression on the OMAP2+ lcdc from a missing
quirk in the ti-sysc driver
- Fix a NULL pointer access from a race in the fsl dpio driver
- Fix a v5.5 regression in the exynos-chipid driver that caused an
invalid error code probing the device on non-exynos platforms
- Fix an out-of-bounds access in the AMD TEE driver

Sorry for the last minute patches, but a few things fell through the cracks
recently. I was on the fence about sending a late PR just for the M-mode
fixes, as we don't really have any users, but the last patch fixes the build
for Fedora which I consider pretty important. Given that the M-mode fixes
should be very low risk, I figured it's worth sending them along as well.

Provide more information about __ex_table sorting post link.
The exception tables and fixup tables use a commonly recurring pattern
in the kernel of storing the address of labels as date in custom ELF
sections, then finding these sections, iterating elements within them,
and possibly revisiting them or modifying the data at these addresses.
Sorting readonly arrays to minimize runtime penalties is quite clever.

Current make_request based drivers use either blk_alloc_queue_node or
blk_alloc_queue to allocate a queue, and then set up the make_request_fn
function pointer and a few parameters using the blk_queue_make_request
helper. Simplify this by passing the make_request pointer to
blk_alloc_queue, and while at it merge the _node variant into the main
helper by always passing a node_id, and remove the superfluous gfp_mask
parameter. A lower-level __blk_alloc_queue is kept for the blk-mq case.

drm/prime: use dma length macro when mapping sg
This switches the EFM32 driver over to use the GPIO descriptor
handling in the core. The GPIO handling in this driver is
pretty simplistic so this should just work. Drop the GPIO headers
and insert the implicitly included <linux/of.h> header.

commit b401f8c4f4 ("USB: cdc-acm: fix rounding error in TIOCSSERIAL")
introduced a regression by changing the order of capability and close
settings change checks. When running with CAP_SYS_ADMIN setting the
close settings to the values already set resulted in -EOPNOTSUPP.
Fix this by changing the check order back to how it was before.

This reverts commit c442a0d187 as it
breaks some of the Raspberry Pi devices. Marek writes:
This patch has just landed in linux-next 20200326. Sadly it
breaks booting of the Raspberry Pi3b and Pi4 boards, either in
32bit or 64bit mode. There is no warning nor panic message, just
a silent freeze. The last message shown on the earlycon is:
[ 0.893217] Serial: 8250/16550 driver, 1 ports, IRQ sharing enabled
so revert it for now and let's try again and add it to linux-next after
5.7-rc1 is out so that we can try to get more debugging/testing
happening.

gcc 10 will default to -fno-common, which causes this error at link
time:
(.text+0x0): multiple definition of `yylloc'; dtc-lexer.lex.o (symbol from plugin):(.text+0x0): first defined here
This is because both dtc-lexer as well as dtc-parser define the same
global symbol yyloc. Before with -fcommon those were merged into one
defintion. The proper solution would be to to mark this as "extern",
however that leads to:
dtc-lexer.l:26:16: error: redundant redeclaration of 'yylloc' [-Werror=redundant-decls]
26 | extern YYLTYPE yylloc;

In file included from dtc-lexer.l:24:
dtc-parser.tab.h:127:16: note: previous declaration of 'yylloc' was here
127 | extern YYLTYPE yylloc;

which means the declaration is completely redundant and can just be

In a context switch from a task that is detecting split locks to one that
is not (or vice versa) we need to update the TEST_CTRL MSR. Currently this
is done with the common sequence:
read the MSR
flip the bit
write the MSR
in order to avoid changing the value of any reserved bits in the MSR.
Cache unused and reserved bits of TEST_CTRL MSR with SPLIT_LOCK_DETECT bit
cleared during initialization, so we can avoid an expensive RDMSR
instruction during context switch.

Current initialization flow of split lock detection has following issues:
1. It assumes the initial value of MSR_TEST_CTRL.SPLIT_LOCK_DETECT to be
zero. However, it's possible that BIOS/firmware has set it.
2. X86_FEATURE_SPLIT_LOCK_DETECT flag is unconditionally set even if
there is a virtualization flaw that FMS indicates the existence while
it's actually not supported.
Rework the initialization flow to solve above issues. In detail, explicitly
clear and set split_lock_detect bit to verify MSR_TEST_CTRL can be
accessed, and rdmsr after wrmsr to ensure bit is cleared/set successfully.
X86_FEATURE_SPLIT_LOCK_DETECT flag is set only when the feature does exist
and the feature is not disabled with kernel param "split_lock_detect=off"
On each processor, explicitly updating the SPLIT_LOCK_DETECT bit based on
sld_sate in split_lock_init() since BIOS/firmware may touch it.

It's old, obsolete, and no one wants to take care of it anymore.
It's been in staging for 5 months with no one paying attention to it, so
let's just delete it for now.
If someone has this hardware, and wants the driver back, the deletion
can be easily reverted.

This patch reverts 5829210483 ("net: ks8851-ml: Fix 16-bit IO operation")
and edacb098ea ("net: ks8851-ml: Fix 16-bit data access"), because it
turns out these were only necessary due to buggy hardware. This patch adds
a check for such a buggy hardware to prevent any such mistakes again.
While working further on the KS8851 driver, it came to light that the
KS8851-16MLL is capable of switching bus endianness by a hardware strap,
EESK pin. If this strap is incorrect, the IO accesses require such endian
swapping as is being reverted by this patch. Such swapping also impacts
the performance significantly.
Hence, in addition to removing it, detect that the hardware is broken,
report to user, and fail to bind with such hardware.

When it's probing all of a fileserver's interfaces to find which one is
best to use, afs_do_probe_fileserver() takes a lock on the server record
and notes the pointer to the address list.
It doesn't, however, pin the address list, so as soon as it drops the
lock, there's nothing to stop the address list from being freed under
us.
Fix this by taking a ref on the address list inside the locked section
and dropping it at the end of the function.

The MAINTAINERS file is one of my least favorite files due to being huge
