818c2b3638 MIPS: ingenic: CI20: enable OST, PWM drivers in defconfig
The OST driver provides a clocksource and sched_clock that are much more
accurate than the default ones.

The PWM driver allows to use the PWM pins on the external header of the
board.

e2e13925ff MIPS: Loongson: Add support for perf tool
In order to use perf tool on the Loongson platform, we should enable kernel
support for various performance events provided by software and hardware,
so add CONFIG_PERF_EVENTS=y to loongson3_defconfig.

E.g. without this patch:

[loongson@localhost perf]$ ./perf list

List of pre-defined events (to be used in -e):

  duration_time                                      [Tool event]

  rNNN                                               [Raw hardware event descriptor]
  cpu/t1=v1[,t2=v2,t3 ...]/modifier                  [Raw hardware event descriptor]
   (see 'man perf-list' on how to encode it)

  mem:<addr>[/len][:access]                          [Hardware breakpoint]

a67bac098d MIPS: CI20: defconfig: multiple improvements
a) configure for supporting modules

Not all drivers need to be compiled into the kernel.
Support building and loading of kernel modules.

b) compile leds-gpio driver into the kernel and configure for LED triggers

DTS has been augmented to add some gpio-leds. We need the leds-gpio driver
and enable the triggers.

c) configure CONFIG_REGULATOR_ACT8865 for PMU

The PMU on the CI20 board is an ACT8600 using the ACT8865 driver.
Since it is not compiled, the PMU and the CI20 board is running in
power-on reset state of the PMU.

d) compile gpio-ir driver

The CI20 board has a gpio based IR receiver.

e) configure for CONFIG_KEYBOARD_GPIO=m

The SW1 button is hooked up to send input events.

679b2ec8e0 scsi: sr: remove references to BLK_DEV_SR_VENDOR, leave it enabled
This kernel configuration is basically enabling/disabling sr driver quirks
detection. While these quirks are for fairly rare devices (very old CD
burners, and a glucometer), the additional detection of these models is a
very minimal amount of code.

The logic behind the quirks is always built into the sr driver.

This also removes the config from all the defconfig files that are enabling
this already.

mips/jazz: Remove redundant settings and shrink jazz_defconfig
Remove some redundant assignments, that have no effect on
'make jazz_defconfig':

CONFIG_INET_XFRM_MODE_TRANSPORT=m
CONFIG_INET_XFRM_MODE_TUNNEL=m
CONFIG_CRYPTO_HMAC=y

Also drop the settings relating to crypto, wireless, advanced
networking etc. The Kconfig defaults for these options are fine.

This reduces the size of vmlinux so it can be launched by
"NetBSD/arc Bootstrap, Revision 1.1", which is conveniently available
on NetBSD/arc 5.1 ISO images.

MIPS: configs: Cleanup old Kconfig options
CONFIG_MTD_NAND_IDS is gone and not needed (part of CONFIG_MTD_NAND)
since commit f16bd7ca04 ("mtd: nand: Kill the MTD_NAND_IDS Kconfig
option").

CONFIG_IOSCHED_DEADLINE, CONFIG_IOSCHED_CFQ and CONFIG_DEFAULT_NOOP are
gone since commit f382fb0bce ("block: remove legacy IO schedulers").

The IOSCHED_DEADLINE was replaced by MQ_IOSCHED_DEADLINE and it will be
now enabled by default (along with MQ_IOSCHED_KYBER).

The BFQ_GROUP_IOSCHED is the only multiqueue scheduler which comes with
group scheduling so select it in configs previously choosing
CFQ_GROUP_IOSCHED.

ad0b314e00 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull sysctl system call removal from Eric Biederman:
 "As far as I can tell we have reached the point where no one enables
  the sysctl system call anymore. It still is enabled in a few
  defconfigs but they are mostly the rarely used one and in asking
  people about that it was more cut & paste enabled than anything else.

  This is single commit that just deletes code. Leaving just enough code
  so that the deprecated sysctl warning continues to be printed. If my
  analysis turns out to be wrong and someone actually cares it will be
  easy to revert this commit and have the system call again.

  There was one new xtensa defconfig in linux-next that enabled the
  system call this cycle and when asked about it the maintainer of the
  code replied that it was not enabled on purpose. As of today's
  linux-next tree that defconfig no longer enables the system call.

  What we saw in the review discussion was that if we go a step farther
  than my patch and mess with uapi headers there are pieces of code that
  won't compile, but nothing minds the system call actually disappearing
  from the kernel"

61a47c1ad3 sysctl: Remove the sysctl system call
This system call has been deprecated almost since it was introduced, and
in a survey of the linux distributions I can no longer find any of them
that enable CONFIG_SYSCTL_SYSCALL.  The only indication that I can find
that anyone might care is that a few of the defconfigs in the kernel
enable CONFIG_SYSCTL_SYSCALL.  However this appears in only 31 of 414
defconfigs in the kernel, so I suspect this symbols presence is simply
because it is harmless to include rather than because it is necessary.

As there appear to be no users of the sysctl system call, remove the
code.  As this removes one of the few uses of the internal kernel mount
of proc I hope this allows for even more simplifications of the proc
filesystem.

MIPS: Loongson: Make default kernel log buffer size as 128KB for Loongson3
When I update kernel with loongson3_defconfig based on the Loongson 3A3000
platform, then using dmesg command to show kernel ring buffer, the initial
kernel messages have disappeared due to the log buffer is too small, it is
better to change the kernel log buffer size from 16KB to 128KB which is
enough to save the boot messages.

Since the default LOG_BUF_SHIFT value is 17, the default kernel log buffer
size is 128KB, just delete the CONFIG_LOG_BUF_SHIFT line.

As later model of GSx64 family processors including 2-series-soc have
similar design with initial loongson3a while loongson2e/f seems less
identical, we separate loongson2e/f support code out of mach-loongson64
to make our life easier.

This patch contains mostly file moving works.

015664d152 USB: rio500: Remove Rio 500 kernel driver
The Rio500 kernel driver has not been used by Rio500 owners since 2001
not long after the rio500 project added support for a user-space USB stack
through the very first versions of usbdevfs and then libusb.

Support for the kernel driver was removed from the upstream utilities
in 2008:

5c6bd5de3c Main MIPS changes for v5.4:
- boot_mem_map is removed, providing a nice cleanup made possible by the
   recent removal of bootmem.
 
 - Some fixes to atomics, in general providing compiler barriers for
   smp_mb__{before,after}_atomic plus fixes specific to Loongson CPUs or
   MIPS32 systems using cmpxchg64().
 
 - Conversion to the new generic VDSO infrastructure courtesy of Vincenzo
   Frascino.
 
 - Removal of undefined behavior in set_io_port_base(), fixing the
   behavior of some MIPS kernel configurations when built with recent
   clang versions.
 
 - Initial MIPS32 huge page support, functional on at least Ingenic SoCs.
 
 - pte_special() is now supported for some configurations, allowing among
   other things generic fast GUP to be used.
 
 - Miscellaneous fixes & cleanups.
 
 And platform specific changes:
 
 - Major improvements to Ingenic SoC support from Paul Cercueil, mostly
   enabled by the inclusion of the new TCU (timer-counter unit) drivers
   he's spent a very patient year or so working on. Plus some fixes for
   X1000 SoCs from Zhou Yanjie.
 
 - Netgear R6200 v1 systems are now supported by the bcm47xx platform.
 
 - DT updates for BMIPS, Lantiq & Microsemi Ocelot systems.

554b3529fe thermal/drivers/core: Remove the module Kconfig's option
The module support for the thermal subsystem makes little sense:
 - some subsystems relying on it are not modules, thus forcing the
   framework to be compiled in
 - it is compiled in for almost every configs, the remaining ones
   are a few platforms where I don't see why we can not switch the thermal
   to 'y'. The drivers can stay in tristate.
 - platforms need the thermal to be ready as soon as possible at boot time
   in order to mitigate

Usually the subsystems framework are compiled-in and the plugs are as
module.

Remove the module option. The removal of the module related dead code will
come after this patch gets in or is acked.

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.

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")

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.

    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

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

  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-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

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

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:

5cbf968803 MIPS: Make CONFIG_MIPS_MT_SMP default y
On systems that support MT ASE multithreading (ie. VPEs) we are very
likely to want to include that support as default. Rather than setting
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.

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.

be configured by setting BOARDS=boston during configuration. For
example:

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.

Pull MIPS updates from James Hogan:
 "Here's the main MIPS pull request for 4.11.

  It contains a few new features such as IRQ stacks, cacheinfo support,
  and KASLR for Octeon CPUs, and a variety of smaller improvements and
  fixes including devicetree additions, kexec cleanups, microMIPS stack
  unwinding fixes, and a bunch of build fixes to clean up continuous
  integration builds.

  far longer.

  Miscellaneous:
   - Add IRQ stacks
   - Add cacheinfo support
   - Add "uzImage.bin" zboot target

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.

4da3273b93 MIPS: OCTEON: Enable DEVTMPFS
Recent versions of udev and systemd require the kernel to be compiled
with CONFIG_DEVTMPFS in order to populate the /dev directory. Most MIPS
platforms have it enabled by default, so enable it for the Cavium Octeon
defconfig as well. This will assist with automated kernel boot testing.
