Christoph Hellwig 72deb455b5 block: remove CONFIG_LBDAF
Currently support for 64-bit sector_t and blkcnt_t is optional on 32-bit
architectures.  These types are required to support block device and/or
file sizes larger than 2 TiB, and have generally defaulted to on for
a long time.  Enabling the option only increases the i386 tinyconfig
size by 145 bytes, and many data structures already always use
64-bit values for their in-core and on-disk data structures anyway,
so there should not be a large change in dynamic memory usage either.

Dropping this option removes a somewhat weird non-default config that
has cause various bugs or compiler warnings when actually used.

Linus Torvalds d1cae94871 fscrypt updates for v5.1
First: Ted, Jaegeuk, and I have decided to add me as a co-maintainer for
 fscrypt, and we're now using a shared git tree.  So we've updated
 MAINTAINERS accordingly, and I'm doing the pull request this time.
 
 The actual changes for v5.1 are:
 
 - Remove the fs-specific kconfig options like CONFIG_EXT4_ENCRYPTION and
   make fscrypt support for all fscrypt-capable filesystems be controlled
   by CONFIG_FS_ENCRYPTION, similar to how CONFIG_QUOTA works.
 
 - Improve error code for rename() and link() into encrypted directories.
 
 - Various cleanups.

MIPS: lantiq: Remove separate GPHY Firmware loader
The separate GPHY Firmware loader driver is not used any more, the GPHY
firmware is now loaded by the GSWIP switch driver which also makes use
of the GPHY.
Remove the old unused GPHY firmware loader driver.

The GPHY firmware is useless without an Ethernet and switch driver, it
should not harm if loading this does not work for system using an old
device tree.
I am not aware of any vendor separating the device tree from the kernel
binary, it should be ok to remove this.

The code and the functionality form this separate GPHY firmware loader
was added to the gswip driver in commit 14fceff477 ("net: dsa: Add
Lantiq / Intel DSA driver for vrx200")

Chandan Rajendra 643fa9612b fscrypt: remove filesystem specific build config option
In order to have a common code base for fscrypt "post read" processing
for all filesystems which support encryption, this commit removes
filesystem specific build config option (e.g. CONFIG_EXT4_FS_ENCRYPTION)
and replaces it with a build option (i.e. CONFIG_FS_ENCRYPTION) whose
value affects all the filesystems making use of fscrypt.

Linus Torvalds 89261c5702 Here's the main MIPS pull for Linux 4.21. Core architecture changes
include:
 
  - Syscall tables & definitions for unistd.h are now generated by
    scripts, providing greater consistency with other architectures &
    making it easier to add new syscalls.
 
  - Support for building kernels with no floating point support, upon
    which any userland attempting to use floating point instructions will
    receive a SIGILL. Mostly useful to shrink the kernel & as preparation
    for nanoMIPS support which does not yet include FP.
 
  - MIPS SIMD Architecture (MSA) vector register context is now exposed
    by ptrace via a new NT_MIPS_MSA regset.
 
  - ASIDs are now stored as 64b values even for MIPS32 kernels, expanding
    the ASID version field sufficiently that we don't need to worry about
    overflow & avoiding rare issues with reused ASIDs that have been
    observed in the wild.
 
  - The branch delay slot "emulation" page is now mapped without write
    permission for the user, preventing its use as a nice location for
    attacks to execute malicious code from.
 
  - Support for ioremap_prot(), primarily to allow gdb or other
    ptrace users the ability to view their tracee's memory using the same
    cache coherency attribute.
 
  - Optimizations to more cpu_has_* macros, allowing more to be
    compile-time constant where possible.
 
  - Enable building the whole kernel with UBSAN instrumentation.
 
  - Enable building the kernel with link-time dead code & data
    elimination.
 
 Platform specific changes include:
 
  - The Boston board gains a workaround for DMA prefetching issues with
    the EG20T Platform Controller Hub that it uses.
 
  - Cleanups to Cavium Octeon code removing about 20k lines of redundant
    code, mostly unused or duplicate register definitions in headers.
 
  - defconfig updates for the DECstation machines, including new
    defconfigs for r4k & 64b machines.
 
  - Further work on Loongson 3 support.
 
  - DMA fixes for SiByte machines.

MIPS: generic: Remove input symbols from defconfig
generic_defconfig explicitly disables CONFIG_INPUT_MOUSEDEV,
CONFIG_INPUT_KEYBOARD & CONFIG_INPUT_MOUSE which results in warnings
when merging board config fragments if any of them require these
options. This is the case for the ranchu board, which means we've had
the following warning when configuring for generic platform targets
since commit f2d0b0d5c1 ("MIPS: ranchu: Add Ranchu as a new
generic-based board"):

  $ make ARCH=mips 32r2el_defconfig
  Using ./arch/mips/configs/generic_defconfig as base
  Merging arch/mips/configs/generic/32r2.config
  Merging arch/mips/configs/generic/el.config
  Merging ./arch/mips/configs/generic/board-sead-3.config
  Merging ./arch/mips/configs/generic/board-ranchu.config
  Value of CONFIG_INPUT_KEYBOARD is redefined by fragment ./arch/mips/configs/generic/board-ranchu.config:
  Previous value: # CONFIG_INPUT_KEYBOARD is not set
  New value: CONFIG_INPUT_KEYBOARD=y

  Merging ./arch/mips/configs/generic/board-ni169445.config
  Merging ./arch/mips/configs/generic/board-boston.config
  Merging ./arch/mips/configs/generic/board-ocelot.config
  Merging ./arch/mips/configs/generic/board-xilfpga.config
  scripts/kconfig/conf  --olddefconfig Kconfig
  #
  # configuration written to .config
  #

Resolve this by removing mention of the CONFIG_INPUT_* Kconfig symbols
from generic_defconfig, allowing them to take their default values &
allowing board config fragments to enable them without warnings.

This may be problematic if CONFIG_ARCH_MIGHT_HAVE_PC_SERIO is ever
enabled for CONFIG_MIPS_GENERIC=y configurations, but for now that isn't
the case so we can worry about that if & when it happens.

The watchdog is an useful piece of hardware, so there's no reason not to
enable it.

Besides, this is important for restart to work after the change in the
next commit.

This commit enables the Kconfig option in the qi_lb60 defconfig.

MIPS: ranchu: Add Ranchu as a new generic-based board
Provide amendments to the MIPS generic platform framework so that
the new generic-based board Ranchu can be chosen to be built.

The Ranchu board is intended to be used by Android emulator. The name
"Ranchu" originates from Android development community. "Goldfish" and
"Ranchu" are terms used for two generations of virtual boards used by
Android emulator. The name "Ranchu" is a newer one among the two, and
this patch deals with Ranchu. However, for historical reasons, some
devices/drivers still contain the name "Goldfish".

MIPS Ranchu machine includes a number of Goldfish devices. The support
for Virtio devices is also included. Ranchu board supports up to 16
Virtio devices which can be attached using Virtio MMIO Bus. This is
summarized in the following picture:

it in various defconfigs, simply make CONFIG_MIPS_MT_SMP default y such
that systems which select CONFIG_SYS_SUPPORTS_MULTITHREADING get it by
default.

As well as allowing us to remove the selection of CONFIG_MIPS_MT_SMP
from various defconfigs, this also allows the generated generic
defconfigs which derive from generic_defconfig to automatically gain
support for MT ASE SMP when building for a suitable (pre-MIPSr6) ISA.

For malta_kvm_guest_defconfig CONFIG_MIPS_MT_SMP is explicitly disabled
since enabling SMP implicitly disables CONFIG_KVM_GUEST, which depends
on CONFIG_BROKEN_ON_SMP.

Paul Burton 9e111ee7c3 MIPS: NI 169445: Only include in 32r2el kernels
The NI 169445 board uses a little endian MIPS32r2 CPU, and therefore
including board support in kernels that are unable to run on such a CPU
is pointless.

Specify requirements in the board config fragment that cause the NI
169445 board support to only be included in generic kernels that target
little endian MIPS32r2 CPUs.

For example, NI 169445 support will be included when configuring using
32r2el_defconfig but not when using 64r6_defconfig.

Paul Burton c7a1d3d8ad MIPS: SEAD-3: Only include in 32 bit kernels by default
The MIPS SEAD-3 development board has only ever been used with 32 bit
CPUs, so including support for it in 64 bit kernels is wasteful since
those kernels will never run on a SEAD-3.

Specify a requirement in the SEAD-3 board config fragment that ensures
the board support is only included in 32 bit kernels, by checking that
CONFIG_32BIT=y.

Paul Burton 6e62a88802 MIPS: generic: Support MIPS Boston development boards
Add support for the MIPS Boston development board to generic kernels,
which essentially amounts to:

  - Adding the device tree source for the MIPS Boston board.

  - Adding a Kconfig fragment which enables the appropriate drivers for
    the MIPS Boston board.

With these changes in place generic kernels will support the board by
default, and kernels with only the drivers needed for Boston enabled can
be configured by setting BOARDS=boston during configuration. For
example:

  $ make ARCH=mips 64r6el_defconfig BOARDS=boston

Matt Redfearn f110cc4f9b MIPS: generic: Enable Root FS on NFS in generic_defconfig
The generic_defconfig is used for platforms like SEAD3 which do not
usually have fixed storage available, therefore NFS is the preferred
location of the RFS.
When the upstream kernel defconfig is built & tested on platforms such
as SEAD3 this leads to essentially false failures when the RFS fails to
mount.

There is little harm in having this feature enabled by default, so
enable it in the defconfig. Kernel autoconfiguration & DHCP must also be
selected to allow RFS on NFS.

Arnd Bergmann b617649468 MIPS: ip27: Disable qlge driver in defconfig
One of the last remaining failures in kernelci.org is for a gcc bug:

drivers/net/ethernet/qlogic/qlge/qlge_main.c:4819:1: error: insn does not satisfy its constraints:
drivers/net/ethernet/qlogic/qlge/qlge_main.c:4819:1: internal compiler error: in extract_constrain_insn, at recog.c:2190

This is apparently broken in gcc-6 but fixed in gcc-7, and I cannot
reproduce the problem here. However, it is clear that ip27_defconfig
does not actually need this driver as the platform has only PCI-X but
not PCIe, and the qlge adapter in turn is PCIe-only.

The driver was originally enabled in 2010 along with lots of other
drivers.

Paul Burton 3f5f0a4475 MIPS: generic: Convert SEAD-3 to a generic board
Convert the MIPS SEAD-3 board support to be a generic board, supported
by generic kernels.

Because the SEAD-3 boot protocol was defined long ago and we don't want
to force a switch to the UHI protocol, SEAD-3 is added as a legacy board
which is detected by reading the REVISION register. This may technically
not be a valid memory read & future work will include attempting to
handle that gracefully. In practice since SEAD-3 is the only legacy
board supported by the generic kernel so far the read will only happen
on SEAD-3 boards, and even once Malta is converted the same REVISION
register exists there too. Other boards such as Boston, Ci20 & Ci40 will
use the UHI boot protocol & thus not run any of the legacy board detect
functions.

Paul Burton eed0eabd12 MIPS: generic: Introduce generic DT-based board support
Introduce a "generic" platform, which aims to be board-agnostic by
making use of device trees passed by the boot protocol defined in the
MIPS UHI (Universal Hosting Interface) specification. Provision is made
for supporting boards which use a legacy boot protocol that can't be
changed, but adding support for such boards or any others is left to
followon patches.

Right now the built kernels expect to be loaded to 0x80100000, ie. in
kseg0. This is fine for the vast majority of MIPS platforms, but
nevertheless it would be good to remove this limitation in the future by
mapping the kernel via the TLB such that it can be loaded anywhere & map
itself appropriately.

Configuration is handled by dynamically generating configs using
scripts/kconfig/merge_config.sh, somewhat similar to the way powerpc
makes use of it. This allows for variations upon the configuration, eg.
differing architecture revisions or subsets of driver support for
differing boards, to be handled without having a large number of
defconfig files.

Paul Burton c11e3b48db MIPS: SEAD3: Probe UARTs using DT
Probe the UARTs on SEAD3 boards using device tree rather than platform
code, in order to reduce the amount of the latter. This requires that
CONFIG_SERIAL_OF_PLATFORM be enabled, so enable it in sead3_defconfig.
The SEAD3 DT shim code is extended to read bootloader environment
variables to determine the appropriate UART & mode for kernel console
output & set the stdout-path property of the chosen node accordingly.

In contrast to the old platform code, which appears to have only ever
set "console=ttyS0,38400n8r" with the code in console_config never
having an effect, this will honor the "yamontty" environment variable to
select between the 2 UARTs on the board and then check the "modetty0" or
"modetty1" variable as appropriate to determine the UART configuration.

Paul Gortmaker 80b7978c60 MIPS: Don't specify STACKPROTECTOR in defconfigs
Only one defconfig has a STACKPROTECTOR value.  And it asks for
the strong variant, which isn't supported by older toolchains.

Due to the nature of MIPS having more platform specific code than say
x86, the allyesconfig and allmodconfig aren't as effective for build
coverage.  So, in addition, I like to use a trivial script to walk all
the defconfigs and build each one.

However I will get false positives on unsupported stackprotector values
with an older toolchain like gcc-4.6.3.  As in this instance I am just
using the compiler as a glorified syntax checker on a machine where I
build a bunch of other arch for the same reason, there is no real
motivation to get a newer toolchain for improved optimization etc.

Since there is only one of them, and there is nothing about these
settings that are board/platform specific, I propose we just eliminate
the existing instance and take the default.

Bartlomiej Zolnierkiewicz 22773aa9b9 MIPS: mpc30x_defconfig: Convert to use libata PATA drivers
IDE subsystem has been deprecated since 2009 and the majority
(if not all) of Linux distributions have switched to use
libata for ATA support exclusively.  However there are still
some users (mostly old or/and embedded non-x86 systems) that
have not converted from using IDE subsystem to libata PATA
drivers.  This doesn't seem to be good thing in the long-term
for Linux as while there is less and less PATA systems left
in use:

* testing efforts are divided between two subsystems

* having duplicate drivers for same hardware confuses users

This patch converts mpc30x_defconfig to use libata PATA
drivers.

PS This platform still uses "ide0=base[,ctl[,irq]]" hack in
its defconfig.  The hack itself has been removed in 2008 and
this platform should be converted to using PATA platform host
driver (pata_platform) instead.

PS This platform uses CS5536 chipset which (due to historical

most likely this platform should switch to using the latter

Bartlomiej Zolnierkiewicz 973852fc0d MIPS: lasat_defconfig: Convert to use libata PATA drivers
IDE subsystem has been deprecated since 2009 and the majority
(if not all) of Linux distributions have switched to use
libata for ATA support exclusively.  However there are still
some users (mostly old or/and embedded non-x86 systems) that
have not converted from using IDE subsystem to libata PATA
drivers.  This doesn't seem to be good thing in the long-term
for Linux as while there is less and less PATA systems left
in use:

* testing efforts are divided between two subsystems

* having duplicate drivers for same hardware confuses users

This patch converts lasat_defconfig to use libata PATA
drivers.

PS This platform still uses "ide0=base[,ctl[,irq]]" hack in
its defconfig.  The hack itself has been removed in 2008 and
this platform should be converted to using PATA platform host
driver (pata_platform) instead.

Now that minor LSMs can cleanly stack with major LSMs, remove the unneeded
config for Yama to be made to explicitly stack. Just selecting the main
Yama CONFIG will allow it to work, regardless of the major LSM. Since
distros using Yama are already forcing it to stack, this is effectively
a no-op change.

Additionally add MAINTAINERS entry.

Huacai Chen 30ad29bb48 MIPS: Loongson: Naming style cleanup and rework
Currently, code of Loongson-2/3 is under loongson directory and code of
Loongson-1 is under loongson1 directory. Besides, there are Kconfig
options such as MACH_LOONGSON and MACH_LOONGSON1. This naming style is
very ugly and confusing. Since Loongson-2/3 are both 64-bit general-
purpose CPU while Loongson-1 is 32-bit SoC, we rename both file names
and Kconfig symbols from loongson/loongson1 to loongson64/loongson32.

Linus Torvalds 510965dd4a This is the bulk of GPIO changes for the v4.1 development
cycle:
 
 - A new GPIO hogging mechanism has been added. This can
   be used on boards that want to drive some GPIO line high,
   low, or set it as input on boot and then never touch it
   again. For some embedded systems this is bliss and
   simplifies things to a great extent.
 
 - Some API cleanup and closure: gpiod_get_array() and
   gpiod_put_array() has been added to get and put GPIOs
   in bulk as was possible with the non-descriptor API.
 
 - Encapsulate cross-calls to the pin control subsystem in
   <linux/gpio/driver.h>. Now this should be the only header
   any GPIO driver needs to include or something is wrong.
   Cleanups restricting drivers to this include are welcomed
   if tested.
 
 - Sort the GPIO Kconfig and split it into submenus, as
   it was becoming and unstructured, illogical and
   unnavigatable mess. I hope this is easier to follow.
   Menus that require a certain subsystem like I2C can
   now be hidden nicely for example, still working on
   others.
 
 - New drivers:
 
     - New driver for the Altera Soft GPIO.
 
     - The F7188x driver now handles the F71869 and
       F71869A variants.
 
     - The MIPS Loongson driver has been moved to
       drivers/gpio for consolidation and cleanup.
 
 - Cleanups:
 
    - The MAX732x is converted to use the GPIOLIB_IRQCHIP
      infrastructure.
 
    - The PCF857x is converted to use the GPIOLIB_IRQCHIP
      infrastructure.
 
    - Radical cleanup of the OMAP driver.
 
 - Misc:
 
    - Enable the DWAPB GPIO for all architectures. This is
      a "hard IP" block from Synopsys which has started to
      turn up in so diverse architectures as X86 Quark, ARC
      and a slew of ARM systems. So even though it's not an
      expander, it's generic enough to be available for all.
 
    - We add a mock GPIO on Crystalcove PMIC after a long
      discussion with Daniel Vetter et al, tracing back to
      the shootout at the kernel summit where DRM drivers
      and sub-componentization was discussed. In this case
      a mock GPIO is assumed to be the best compromise
      gaining some reuse of infrastructure without making
      DRM drivers overly complex at the same time. Let's
      see.

Linus Torvalds a135c717d5 Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
 "This is the main pull request for MIPS:

   - a number of fixes that didn't make the 3.19 release.

   - a number of cleanups.

   - preliminary support for Cavium's Octeon 3 SOCs which feature up to
     48 MIPS64 R3 cores with FPU and hardware virtualization.

   - support for MIPS R6 processors.

     Revision 6 of the MIPS architecture is a major revision of the MIPS
     architecture which does away with many of original sins of the
     architecture such as branch delay slots.  This and other changes in
     R6 require major changes throughout the entire MIPS core
     architecture code and make up for the lion share of this pull
     request.

   - finally some preparatory work for eXtendend Physical Address
     support, which allows support of up to 40 bit of physical address
     space on 32 bit processors"

     [ Ahh, MIPS can't leave the PAE brain damage alone.  It's like
       every CPU architect has to make that mistake, but pee in the snow
       by changing the TLA.  But whether it's called PAE, LPAE or XPA,
       it's horrid crud   - Linus ]
