143463fd33 MIPS: Loongson: Enable devicetree based probing for 8250 ports in defconfig
After commit 87fcfa7b7f ("MIPS: Loongson64: Add generic dts"),
there already exists the node and property of Loongson CPU UART0
in loongson3-package.dtsi:

cpu_uart0: serial@1fe001e0 {
        compatible = "ns16550a";
        reg = <0 0x1fe001e0 0x8>;
        clock-frequency = <33000000>;
        interrupt-parent = <&liointc>;
        interrupts = <10 IRQ_TYPE_LEVEL_HIGH>;
        no-loopback-test;
};

In order to support for serial console on the Loongson platform,
add CONFIG_SERIAL_OF_PLATFORM=y to loongson3_defconfig.

With this patch, we can see the following boot messages:

[    1.877745] printk: console [ttyS0] disabled
[    1.881979] 1fe001e0.serial: ttyS0 at MMIO 0x1fe001e0 (irq = 16, base_baud = 2062500) is a 16550A
[    1.890838] printk: console [ttyS0] enabled

And also, we can login normally from the serial console.

a44de7497f MIPS: Loongson: Build ATI Radeon GPU driver as module
When ATI Radeon GPU driver has been compiled directly into the kernel
instead of as a module, we should make sure the firmware for the model
(check available ones in /lib/firmware/radeon) is built-in to the kernel
as well, otherwise there exists the following fatal error during GPU init,
change CONFIG_DRM_RADEON=y to CONFIG_DRM_RADEON=m to fix it.

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.

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.

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.

- Fix VDSO time-related function behavior for systems where we need to
   fall back to syscalls, but were instead returning bogus results.
 
 - A fix to TLB exception handlers for Cavium Octeon systems where they
   would inadvertently clobber the $1/$at register.

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.

MIPS: Fork loongson2ef from loongson64
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.

- 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.

92fab77b6b Main MIPS changes for v5.2:
- A set of memblock initialization improvements thanks to Serge Semin,
   tidying up after our conversion from bootmem to memblock back in
   v4.20.
 
 - Our eBPF JIT the previously supported only MIPS64r2 through MIPS64r5
   is improved to also support MIPS64r6. Support for MIPS32 systems is
   introduced, with the caveat that it only works for programs that don't
   use 64 bit registers or operations - those will bail out & need to be
   interpreted.
 
 - Improvements to the allocation & configuration of our exception vector
   that should fix issues seen on some platforms using recent versions of
   U-Boot.
 
 - Some minor improvements to code generated for jump labels, along with
   enabling them by default for generic kernels.

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")

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.

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 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"
