treewide: replace '---help---' in Kconfig files with 'help'
kbuild: fix broken builds because of GZIP,BZIP2,LZOP variables
samples: binderfs: really compile this sample and fix build issues
Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

EFI on ARM only supports short descriptors, and given that it mandates
that the MMU and caches are on, it is implied that booting in HYP mode
is not supported.
However, implementations of EFI exist (i.e., U-Boot) that ignore this
requirement, which is not entirely unreasonable, given that it makes
HYP mode inaccessible to the operating system.
So let's make sure that we can deal with this condition gracefully.
We already tolerate booting the EFI stub with the caches off (even
though this violates the EFI spec as well), and so we should deal
with HYP mode boot with MMU and caches either on or off.
- When the MMU and caches are on, we can ignore the HYP stub altogether,
since we can carry on executing at HYP. We do need to ensure that we
disable the MMU at HYP before entering the kernel proper.
- When the MMU and caches are off, we have to drop to SVC mode so that
we can set up the page tables using short descriptors. In this case,
we need to install the HYP stub as usual, so that we can return to HYP
mode before handing over to the kernel proper.

ZBOOT_ROM_TEXT and ZBOOT_ROM_BSS are defined as 'hex' but had a default
of "0". Kconfig will helpfully expand a text entry of 0 to 0x0 but
because this is not the same as the default value it was treated as
being explicitly set when running 'make savedefconfig' so most arm
defconfigs have CONFIG_ZBOOT_ROM_TEXT=0x0 and CONFIG_ZBOOT_ROM_BSS=0x0.
Change the default to 0x0 which will mean next time the defconfigs are
re-generated the spurious config entries will be removed.

Redefine GZIP, BZIP2, LZOP variables as KGZIP, KBZIP2, KLZOP resp.
GZIP, BZIP2, LZOP env variables are reserved by the tools. The original
attempt to redefine them internally doesn't work in makefiles/scripts
intercall scenarios, e.g., "make GZIP=gzip bindeb-pkg" and results in
broken builds. There can be other broken build commands because of this,
so the universal solution is to use non-reserved env variables for the
compression tools.

Pull READ/WRITE_ONCE rework from Will Deacon:
"This the READ_ONCE rework I've been working on for a while, which
bumps the minimum GCC version and improves code-gen on arm64 when
stack protector is enabled"
[ Side note: I'm _really_ tempted to raise the minimum gcc version to
4.9, so that we can just say that we require _Generic() support.
That would allow us to more cleanly handle a lot of the cases where we
depend on very complex macros with 'sizeof' or __builtin_choose_expr()
with __builtin_types_compatible_p() etc.
This branch has a workaround for sparse not handling _Generic(),
either, but that was already fixed in the sparse development branch,
so it's really just gcc-4.9 that we'd require. - Linus ]

function that isn't used anymore. Otherwise the main new thing for the common
clk framework is that it is selectable in the Kconfig language now. Hopefully
this will let clk drivers and clk consumers be testable on more than the
architectures that support the clk framework. The goal is to introduce some
Kunit tests for the framework.
Outside of the core framework we have the usual set of various driver updates
and non-critical fixes. The dirstat shows that the new Baikal-T1 driver is the
largest addition this time around in terms of lines of code. After that the x86
(Intel), Qualcomm, and Mediatek drivers introduce many lines to support new or
upcoming SoCs. After that the dirstat shows the usual suspects working on their
SoC support by fixing minor bugs, correcting data and converting some of their
DT bindings to YAML.
Core:
- Allow the COMMON_CLK config to be selectable
New Drivers:
- Clk driver for Baikal-T1 SoCs
- Mediatek MT6765 clock support
- Support for Intel Agilex clks
- Add support for X1830 and X1000 Ingenic SoC clk controllers
- Add support for the new Renesas RZ/G1H (R8A7742) SoC

- Bunch of updates for HSDK clock generation unit (CGU) driver
- Start making audio and GPU clks work on Marvell MMP2/MMP3 SoCs
- Add some GPU, NPU, and UFS clks to Qualcomm SM8150 driver
- Enable supply regulators for GPU gdscs on Qualcomm SoCs
- Add support for Si5342, Si5344 and Si5345 chips
- Support custom flags in Xilinx zynq firmware
- Various small fixes to the Xilinx clk driver
- A single minor rounding fix for the legacy Allwinner clock support
- A few patches from Abel Vesa as preparation of adding audiomix clock support
on i.MX
- A couple of cleanups from Anson Huang for i.MX clk-sscg-pll and clk-pllv3
drivers

All architectures define pte_index() as
(address >> PAGE_SHIFT) & (PTRS_PER_PTE - 1)
and all architectures define pte_offset_kernel() as an entry in the array
of PTEs indexed by the pte_index().
For the most architectures the pte_offset_kernel() implementation relies
on the availability of pmd_page_vaddr() that converts a PMD entry value to
the virtual address of the page containing PTEs array.
Let's move x86 definitions of the PTE accessors to the generic place in
<linux/pgtable.h> and then simply drop the respective definitions from the
other architectures.
The architectures that didn't provide pmd_page_vaddr() are updated to have
that defined.
The generic implementation of pte_offset_kernel() can be overridden by an
architecture and alpha makes use of this because it has special ordering
requirements for its version of pte_offset_kernel().

Patch series "mm: consolidate definitions of page table accessors", v2.
The low level page table accessors (pXY_index(), pXY_offset()) are
duplicated across all architectures and sometimes more than once. For
instance, we have 31 definition of pgd_offset() for 25 supported
architectures.
Most of these definitions are actually identical and typically it boils
down to, e.g.
static inline unsigned long pmd_index(unsigned long address)
{
return (address >> PMD_SHIFT) & (PTRS_PER_PMD - 1);
}
static inline pmd_t *pmd_offset(pud_t *pud, unsigned long address)
{
return (pmd_t *)pud_page_vaddr(*pud) + pmd_index(address);
}
These definitions can be shared among 90% of the arches provided
XYZ_SHIFT, PTRS_PER_XYZ and xyz_page_vaddr() are defined.
For architectures that really need a custom version there is always
possibility to override the generic version with the usual ifdefs magic.
These patches introduce include/linux/pgtable.h that replaces
include/asm-generic/pgtable.h and add the definitions of the page table
accessors to the new header.
This patch (of 12):
The linux/mm.h header includes <asm/pgtable.h> to allow inlining of the
functions involving page table manipulations, e.g. pte_alloc() and
pmd_alloc(). So, there is no point to explicitly include <asm/pgtable.h>
in the files that include <linux/mm.h>.
The include statements in such cases are remove with a simple loop:
for f in $(git grep -l "include <linux/mm.h>") ; do
sed -i -e '/include <asm\/pgtable.h>/ d' $f
done

Currently, the log-level of show_stack() depends on a platform
realization. It creates situations where the headers are printed with
lower log level or higher than the stacktrace (depending on a platform or
user).
Furthermore, it forces the logic decision from user to an architecture
side. In result, some users as sysrq/kdb/etc are doing tricks with
temporary rising console_loglevel while printing their messages. And in
result it not only may print unwanted messages from other CPUs, but also
omit printing at all in the unlucky case where the printk() was deferred.
Introducing log-level parameter and KERN_UNSUPPRESSED [1] seems an easier
approach than introducing more printk buffers. Also, it will consolidate
printings with headers.
Introduce show_stack_loglvl(), that eventually will substitute
show_stack().

Patch series "sort out the flush_icache_range mess", v2.
flush_icache_range is mostly used for kernel address, except for the
following cases:
- the nommu brk and mmap implementations
- the read_code helper that is only used for binfmt_flat,
binfmt_elf_fdpic, and binfmt_aout including the broken
ia32 compat version
- binfmt_flat itself
none of which really are used by a typical MMU enabled kernel, as a.out
can only be build for alpha and m68k to start with.
But strangely enough commit ae92ef8a44 ("PATCH] flush icache in
correct context") added a "set_fs(KERNEL_DS)" around the
flush_icache_range call in the module loader, because apparently m68k
assumed user pointers.
This series first cleans up the cacheflush implementations, largely by
switching as much as possible to the asm-generic version after a few
preparations, then moves the misnamed current flush_icache_user_range to
a new name, to finally introduce a real flush_icache_user_range to be
used for the above use cases to flush the instruction cache for a
userspace address range. The last patch then drops the set_fs in the
module code and moves it into the m68k implementation.
This patch (of 29):
The arguments passed look bogus, try to fix them to something that seems
to make sense.

'make modules_install' because it is useful even when
CONFIG_MODULES=n
- add new command line variables, GZIP, BZIP2, LZOP, LZMA, LZ4, and XZ
to allow users to use alternatives such as pigz, pbzip2, etc.

Allow user to use alternative implementations of compression tools,
such as pigz, pbzip2, pxz. For example, multi-threaded tools to
speed up the build:
$ make GZIP=pigz BZIP2=pbzip2
Variables _GZIP, _BZIP2, _LZOP are used internally because original env
vars are reserved by the tools. The use of GZIP in gzip tool is obsolete
since 2015. However, alternative implementations (e.g., pigz) still rely
on it. BZIP2, BZIP, LZOP vars are not obsolescent.
The credit goes to @grsecurity.
As a sidenote, for multi-threaded lzma, xz compression one can use:
$ export XZ_OPT="--threads=0"

One new platform gets added, the Realtek RTD1195, which is an older
Cortex-a7 based relative of the RTD12xx chips that are already supported
in arch/arm64. The platform may also be extended to support running
32-bit kernels on those 64-bit chips for memory-constrained machines.
In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742,
an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally
released in 2016 as one of the last high-end 32-bit designs.
There is ongoing cleanup for the integrator, tegra, imx, and omap2
platforms, with integrator getting very close to the goal of having
zero code in arch/arm/, and omap2 moving more of the chip specifics
from old board code into device tree files.
The Versatile Express platform is made more modular, with built-in
drivers now becoming loadable modules. This is part of a greater effort
for the Android OS to have a common kernel binary for all platforms and
any platform specific code in loadable modules.
The PXA platform drops support for Compulab's pxa2xx boards that had
rather unusual flash and PCI drivers but no known users remaining.
All device drivers specific to those boards can now get removed as
well.
Across platforms, there is ongoing cleanup, with Geert and Rob
revisiting some a lot of Kconfig options.

To support kmap_atomic_prot(), all architectures need to support
protections passed to their kmap_atomic_high() function. Pass protections
into kmap_atomic_high() and change the name to kmap_atomic_high_prot() to
match.
Then define kmap_atomic_prot() as a core function which calls
kmap_atomic_high_prot() when needed.
Finally, redefine kmap_atomic() as a wrapper of kmap_atomic_prot() with
the default kmap_prot exported by the architectures.

pagefault_enable();
preempt_enable();
... before returning from __kunmap_atomic(). Lift this code into the

While we are at it rename __kunmap_atomic() to kunmap_atomic_high() to
be consistent.

Every arch has the same code to ensure atomic operations and a check for
!HIGHMEM page.
Remove the duplicate code by defining a core kmap_atomic() which only
calls the arch specific kmap_atomic_high() when the page is high memory.

All architectures do exactly the same thing for kunmap(); remove all the
duplicate definitions and lift the call to the core.
This also has the benefit of changing kmap_unmap() on a number of
architectures to be an inline call rather than an actual function.

Patch series "Remove duplicated kmap code", v3.
The kmap infrastructure has been copied almost verbatim to every
architecture. This series consolidates obvious duplicated code by
defining core functions which call into the architectures only when
needed.
Some of the k[un]map_atomic() implementations have some similarities but
the similarities were not sufficient to warrant further changes.
In addition we remove a duplicate implementation of kmap() in DRM.
This patch (of 15):
Replace the use of BUG_ON(in_interrupt()) in the kmap() and kunmap() in
favor of might_sleep().
Besides the benefits of might_sleep(), this normalizes the implementations
such that they can be made generic in subsequent patches.

Pull media updates from Mauro Carvalho Chehab:
- Media documentation is now split into admin-guide, driver-api and
userspace-api books (a longstanding request from Jon);
- The media Kconfig was reorganized, in order to make easier to select
drivers and their dependencies;
- The testing drivers now has a separate directory;
- added a new driver for Rockchip Video Decoder IP;
- The atomisp staging driver was resurrected. It is meant to work with
4 generations of cameras on Atom-based laptops, tablets and cell
phones. So, it seems worth investing time to cleanup this driver and
making it in good shape.
- Added some V4L2 core ancillary routines to help with h264 codecs;
- Added an ov2740 image sensor driver;
- The si2157 gained support for Analog TV, which, in turn, added
support for some cx231xx and cx23885 boards to also support analog
standards;
- Added some V4L2 controls (V4L2_CID_CAMERA_ORIENTATION and
V4L2_CID_CAMERA_SENSOR_ROTATION) to help identifying where the camera
is located at the device;
- VIDIOC_ENUM_FMT was extended to support MC-centric devices;
- Lots of drivers improvements and cleanups.

pmd_present() is expected to test positive after pmdp_mknotpresent() as
the PMD entry still points to a valid huge page in memory.
pmdp_mknotpresent() implies that given PMD entry is just invalidated from
MMU perspective while still holding on to pmd_page() referred valid huge
page thus also clearing pmd_present() test. This creates the following
situation which is counter intuitive.
[pmd_present(pmd_mknotpresent(pmd)) = true]
This renames pmd_mknotpresent() as pmd_mkinvalid() reflecting the helper's
functionality more accurately while changing the above mentioned situation
as follows. This does not create any functional change.
[pmd_present(pmd_mkinvalid(pmd)) = true]
This is not applicable for platforms that define own pmdp_invalidate() via
__HAVE_ARCH_PMDP_INVALIDATE. Suggestion for renaming came during a
previous discussion here.
