git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux into mtd/next
Backmerge v4.16-rc2 into mtd/next to resolve a conflict between Linus'
master branch and nand/for-4.17.
|
|
Core changes:
* Prepare arrival of the SPI NAND subsystem by implementing a generic
(interface-agnostic) layer to ease manipulation of NAND devices
* Move onenand code base to the drivers/mtd/nand/ dir
* Rework timing mode selection
* Provide a generic way for NAND chip drivers to flag a specific
GET/SET FEATURE operation as supported/unsupported
* Stop embedding ONFI/JEDEC param page in nand_chip
Driver changes:
* Rework/cleanup of the mxc driver
* Various cleanups in the vf610 driver
* Migrate the fsmc and vf610 to ->exec_op()
* Get rid of the pxa driver (replaced by marvell_nand)
* Support ->setup_data_interface() in the GPMI driver
* Fix probe error path in several drivers
* Remove support for unused hw_syndrome mode in sunxi_nand
* Various minor improvements
|
|
* Make fsl-quaspi assign different names to MTD devices connected
to the same QSPI controller
* Remove an unneeded driver.bus assigned in the fsl-qspi driver
|
|
Improve the bindings example by adding an example of how to represent
two SPI NOR devices.

This mode is not used by any existing setup and should not be used

On Armada 7K/8K we need to explicitly enable the register clock. This
clock is optional because not all the SoCs using this IP need it but at
least for Armada 7K/8K it is actually mandatory.
The binding documentation is updated accordingly.

test_and_{}_bit()
A test_and_{}_bit() operation fails if the value of the bit is such that
the modification does not take place. For example, if test_and_set_bit()
returns 1. In these cases, follow the behaviour of cmpxchg and allow the
operation to be unordered. This also applies to test_and_set_bit_lock()
if the lock is found to be be taken already.

Pull s390 updates from Heiko Carstens:
"The main thing in this merge is the defense for the Spectre
vulnerabilities. But there are other updates as well, the changes in
more detail:
- An s390 specific implementation of the array_index_mask_nospec
function to the defense against spectre v1
- Two patches to utilize the new PPA-12/PPA-13 instructions to run
the kernel and/or user space with reduced branch predicton.
- The s390 variant of the 'retpoline' spectre v2 defense called
'expoline'. There is no return instruction for s390, instead an
indirect branch is used for function return
The s390 defense mechanism for indirect branches works by using an
execute-type instruction with the indirect branch as the target of
the execute. In effect that turns off the prediction for the
indirect branch.
- Scrub registers in entry.S that contain user controlled values to
prevent the speculative use of these values.
- Re-add the second parameter for the s390 specific runtime
instrumentation system call and move the header file to uapi. The
second parameter will continue to do nothing but older kernel
versions only accepted valid real-time signal numbers. The details
will be documented in the man-page for the system call.
- Corrections and improvements for the s390 specific documentation
- Add a line to /proc/sysinfo to display the CPU model dependent
license-internal-code identifier
- A header file include fix for eadm.
- An error message fix in the kprobes code.
- The removal of an outdated ARCH_xxx select statement"

Pointer subtraction is slow and tedious. Therefore, replace all instances
where cpufreq_for_each_{valid_,}entry loops contained such substractions
with an iteration macro providing an index to the frequency_table entry.

SPCR is currently only enabled or ARM64 and x86 can use SPCR to setup
an early console.
General fixes include updating Documentation & Kconfig (for x86),
updating comments, and changing parse_spcr() to acpi_parse_spcr(),
and earlycon_init_is_deferred to earlycon_acpi_spcr_enable to be
more descriptive.
On x86, many systems have a valid SPCR table but the table version is
not 2 so the table version check must be a warning.
On ARM64 when the kernel parameter earlycon is used both the early console
and console are enabled. On x86, only the earlycon should be enabled by
by default. Modify acpi_parse_spcr() to allow options for initializing
the early console and console separately.

worked fine with NVMe over Fabrics and mlx5 adapters. That broke in

Support the AFS dynamic root which is a pseudo-volume that doesn't connect
to any server resource, but rather is just a root directory that
dynamically creates mountpoint directories where the name of such a
directory is the name of the cell.
Such a mount can be created thus:
mount -t afs none /afs -o dyn
Dynamic root superblocks aren't shared except by bind mounts and
propagation. Cell root volumes can then be mounted by referring to them by
name, e.g.:
ls /afs/grand.central.org/
ls /afs/.grand.central.org/
The kernel will upcall to consult the DNS if the address wasn't supplied
directly.

Pull pwm updates from Thierry Reding:
"The Meson PWM controller driver gains support for the AXG series and a
minor bug is fixed for the STMPE driver.
To round things off, the class is now set for PWM channels exported
via sysfs which allows non-root access, provided that the system has
been configured accordingly"
* tag 'pwm/for-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm:
pwm: meson: Add clock source configuration for Meson-AXG
dt-bindings: pwm: Update bindings for the Meson-AXG
pwm: stmpe: Fix wrong register offset for hwpwm=2 case
pwm: Set class for exported channels in sysfs

The SK_MEM_QUANTUM was changed from PAGE_SIZE to 4096. And the
tcp_wmem/tcp_rmem min default values are 4096.
Fixes: bd68a2a854ad ("net: set SK_MEM_QUANTUM to 4096")
