As of today the CONFIG_USB isn't explicitly present in HSDK defconfig
as it is implicitly forcibly enabled by UDL driver which selects CONFIG_USB
in its kconfig.
The commit 5d50bd440bc2 ("drm/udl: Make udl driver depend on CONFIG_USB")
reverse the dependencies between UDL and USB so UDL now depends on
CONFIG_USB and not selects it. This introduces regression for ARC HSDK
board as HSDK defconfig wasn't adjusted and now it misses USB support
due to lack of CONFIG_USB enabled.Fix that.

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"Link: https://lore.kernel.org/lkml/201910011140.EA0181F13@keescook/

sysctl: Remove the sysctl system call
27 Nov, 2019
1 commit
-
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.Cc: Alex Smith

Starting from nSIM 2019.06 is possible to use DW UART
instead of ARC UART. That allows us to merge
"nsim_hs" with "haps_hs" and "nsim_hs_smp" with "haps_hs_smp"
with minor changes which were done in previous commits.We eliminate nsim_hs_defconfig and nsim_hs_smp_defconfig
and leave haps_hs_defconfig and haps_hs_smp_defconfig
which can be used on HAPS / nSIM / ZEBU / QEMU platforms
without additional changes in Linux kernel.For nSIM we should now use UART property values
"-prop=nsim_mem-dev=uart0,kind=dwuart,base=0xf0000000"
instead of previously used
"-prop=nsim_mem-dev=uart0,base=0xc0fc1000"
"use_connect" and "irq" values of UART property remains untouched.Signed-off-by: Eugeniy Paltsev

arch/arc/Makefile overrides -O2 with -O3. This is the only user of
ARCH_CFLAGS. There is no user of ARCH_CPPFLAGS or ARCH_AFLAGS.
My plan is to remove ARCH_{CPP,A,C}FLAGS after refactoring the ARC
Makefile.Currently, ARC has no way to enable -Wmaybe-uninitialized because both
-O3 and -Os disable it. Enabling it will be useful for compile-testing.
This commit allows allmodconfig (, which defaults to -O2) to enable it.Add CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3=y to all the defconfig files
in arch/arc/configs/ in order to keep the current config settings.Signed-off-by: Masahiro Yamada

As a preparation for QEMU usage for ARC let's add basic Virtio-MMIO
peripherals support for the platform we're going to use.For now we add 5 Virtio slots in .dts and enable block and network devices
via Virtio-MMIO.Note even though typically Virtio register set fits in 0x200 bytes
we "allocate" here 0x2000 so that it matches ARC's default 8KiB page size
and so remapping of that area is done clearly.We also enable DEVTMPFS automount for more convenient use
of external root file-stystem. Before that we used to use built-in
Initramfs which didn't automount DEVTMPFS anyways so we didn't need
that option, while now it starts making sense.Signed-off-by: Alexey Brodkin

Commit 5318321d367c ("samples: disable CONFIG_SAMPLES for UML") used
a big hammer to fix the build errors under the samples/ directory.
Only some samples actually include uapi headers from usr/include.Introduce CONFIG_HEADERS_INSTALL since 'depends on HEADERS_INSTALL' is
clearer than 'depends on !UML'. If this option is enabled, uapi headers
are installed before starting directory descending.I added 'depends on HEADERS_INSTALL' to per-sample CONFIG options.
This allows UML to compile some samples.$ make ARCH=um allmodconfig samples/

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.Signed-off-by: Christoph Hellwig

Change the default defconfig (used with 'make defconfig') to the ARCv2
nsim_hs_defconfig, and also switch the default Kconfig ISA selection to
ARCv2.This allows several default defconfigs (e.g. make defconfig, make
allnoconfig, make tinyconfig) to all work with ARCv2 by default.Note since we change default architecture from ARCompact to ARCv2
it's required to explicitly mention architecture type in ARCompact
defconfigs otherwise ARCv2 will be implied and binaries will be

Currently there're 2 different implementations of the driver for
DisplayLink USB2.0-to-HDMI/DVI adapters: older FBDEV and modern true
DRM.We initially decided to use FBDEV version just because with it
/dev/fbX is usable from user-space while in DRM version
with DRM_FBDEV_EMULATION user-space cannot draw anything on a real
screen, for more info read [1].But today /dev/fbX is not that important as more and more software
projects switch to use of DRI (/dev/dri/cardX).But what's even more important DRM driver allows building of complicated
graphics processing chains. The most important for us is rendering of
3D on a dedicated GPU while outputting video through a simpler
bitstreamer like DisplayLink. So let's use much more future-proof
driver from now on.[1] https://lists.freedesktop.org/archives/dri-devel/2017-December/159519.html
