Currently, CONFIG_JUMP_LABEL just means "I _want_ to use jump label".
The jump label is controlled by HAVE_JUMP_LABEL, which is defined
like this:
#if defined(CC_HAVE_ASM_GOTO) && defined(CONFIG_JUMP_LABEL)
# define HAVE_JUMP_LABEL
#endif
We can improve this by testing 'asm goto' support in Kconfig, then
make JUMP_LABEL depend on CC_HAS_ASM_GOTO.
Ugly #ifdef HAVE_JUMP_LABEL will go away, and CONFIG_JUMP_LABEL will
match to the real kernel capability.

Patch series "Add support for fast mremap".
This series speeds up the mremap(2) syscall by copying page tables at
the PMD level even for non-THP systems. There is concern that the extra
'address' argument that mremap passes to pte_alloc may do something
subtle architecture related in the future that may make the scheme not
work. Also we find that there is no point in passing the 'address' to
pte_alloc since its unused. This patch therefore removes this argument
tree-wide resulting in a nice negative diff as well. Also ensuring
along the way that the enabled architectures do not do anything funky
with the 'address' argument that goes unnoticed by the optimization.
Build and boot tested on x86-64. Build tested on arm64. The config
enablement patch for arm64 will be posted in the future after more
testing.
The changes were obtained by applying the following Coccinelle script.
(thanks Julia for answering all Coccinelle questions!).
Following fix ups were done manually:
* Removal of address argument from pte_fragment_alloc
* Removal of pte_alloc_one_fast definitions from m68k and microblaze.

Nobody has actually used the type (VERIFY_READ vs VERIFY_WRITE) argument
of the user address range verification function since we got rid of the
old racy i386-only code to walk page tables by hand.
It existed because the original 80386 would not honor the write protect
bit when in kernel mode, so you had to do COW by hand before doing any
user access. But we haven't supported that in a long time, and these
days the 'type' argument is a purely historical artifact.
A discussion about extending 'user_access_begin()' to do the range
checking resulted this patch, because there is no way we're going to
move the old VERIFY_xyz interface to that model. And it's best done at
the end of the merge window when I've done most of my merges, so let's
just get this done once and for all.
This patch was mostly done with a sed-script, with manual fix-ups for
the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form.
There were a couple of notable cases:
- csky still had the old "verify_area()" name as an alias.
- the iter_iov code had magical hardcoded knowledge of the actual
values of VERIFY_{READ,WRITE} (not that they mattered, since nothing
really used it)
- microblaze used the type argument for a debug printout
but other than those oddities this should be a total no-op patch.
I tried to fix up all architectures, did fairly extensive grepping for
access_ok() uses, and the changes are trivial, but I may have missed
something. Any missed conversion should be trivially fixable, though.

Pull ARM SoC defconfig updates from Olof Johansson:
"Most changes here are to enable new drivers and platforms in the
various configs that affect them. Most of these have been covered and
described in the other branches, we mostly keep defconfig separate to
avoid conflicts between SoC/dt/driver updates that they otherwise
would be grouped with.
One thing worth mentioning here is that OMAP changes from using their
own UART driver, to 8250, for the multi_v7_defconfig shared config on
32-bit. This means that the console is now named ttyS* instead of
ttyO*. This change was already done for omap2_defconfig a while back,
so most users of these configs have either already updated, or can
easily follow the same patterns as they did at that time. This makes
platform support slightly easier for distros, since they no longer
need to keep track of a separate console prefix for these platforms"

Pull ARM Device-tree updates from Olof Johansson:
"As usual, this is where the bulk of our changes end up landing each
merge window.
The individual updates are too many to enumerate, many many platforms
have seen additions of device descriptions such that they are
functionally more complete (in fact, this is often the bulk of updates
we see).
Instead I've mostly focused on highlighting the new platforms below as
they are introduced. Sometimes the introduction is of mostly a
fragment, that later gets filled in on later releases, and in some
cases it's near-complete platform support. The latter is more common
for derivative platforms that already has similar support in-tree.
Two SoCs are slight outliers from the usual range of additions.

in the Lychee Pi Nano platform. At the other end is NXP Layerscape
LX2160A, a 16-core 2.2GHz Cortex-A72 SoC with a large amount of I/O
aimed at infrastructure/networking.
TI updates stick out in the diff stats too, in particular because they
have moved the description of their L4 on-chip interconnect to
devicetree, which opens up for removal of even more of their
platform-specific 'hwmod' description tables over the next few
releases.

---[ end trace adf21f830c46e638 ]---
Looking closely at it, it seems like a really bad idea to be calling
local_irq_enable() in kgdb_roundup_cpus(). If nothing else that seems
like it could violate spinlock semantics and cause a deadlock.
Instead, let's use a private csd alongside
smp_call_function_single_async() to round up the other CPUs. Using
smp_call_function_single_async() doesn't require interrupts to be
enabled so we can remove the offending bit of code.
In order to avoid duplicating this across all the architectures that
use the default kgdb_roundup_cpus(), we'll add a "weak" implementation
to debug_core.c.
Looking at all the people who previously had copies of this code,
there were a few variants. I've attempted to keep the variants
working like they used to. Specifically:
* For arch/arc we passed NULL to kgdb_nmicallback() instead of
get_irq_regs().
* For arch/mips there was a bit of extra code around
kgdb_nmicallback()
NOTE: In this patch we will still get into trouble if we try to round
up a CPU that failed to round up before. We'll try to round it up
again and potentially hang when we try to grab the csd lock. That's
not new behavior but we'll still try to do better in a future patch.

Pull Devicetree updates from Rob Herring:
"The biggest highlight here is the start of using json-schema for DT
bindings. Being able to validate bindings has been discussed for years
with little progress.
- Initial support for DT bindings using json-schema language. This is
the start of converting DT bindings from free-form text to a
structured format.
- Reworking of initrd address initialization. This moves to using the
phys address instead of virt addr in the DT parsing code. This
rework was motivated by CONFIG_DEV_BLK_INITRD causing unnecessary
rebuilding of lots of files.
- Fix stale phandle entries in phandle cache
- DT overlay validation improvements. This exposed several memory
leak bugs which have been fixed.
- Use node name and device_type helper functions in DT code
- Last remaining conversions to using %pOFn printk specifier instead
of device_node.name directly
- Create new common RTC binding doc and move all trivial RTC devices
out of trivial-devices.txt.

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.21 kernel series.
Core changes:
- Some core changes are already in outside of this pull request as
they came through the regulator tree, most notably
devm_gpiod_unhinge() that removes devres refcount management from a
GPIO descriptor. This is needed in subsystems such as regulators
where the regulator core need to take over the reference counting
and lifecycle management for a GPIO descriptor.
- We dropped devm_gpiochip_remove() and devm_gpio_chip_match() as
nothing needs it. We can bring it back if need be.
- Add a global TODO so people see where we are going. This helps
setting the direction now that we are two GPIO maintainers.
- Handle the MMC CD/WP properties in the device tree core. (The bulk
of patches activating this code is already merged through the
MMC/SD tree.)
- Augment gpiochip_request_own_desc() to pass a flag so we as
gpiochips can request lines as active low or open drain etc even
from ourselves.
New drivers:
- New driver for Cadence GPIO blocks.
- New driver for Atmel SAMA5D2 PIOBU GPIO lines.
Driver improvements:
- A major refactoring of the PCA953x driver - this driver has been
around for ages, and is now modernized to reduce code duplication
that has stacked up and is using regmap to read write and cache
registers.
- Intel drivers are now maintained in a separate tree and start with
a round of cleanups and unifications"

Pull DMA mapping updates from Christoph Hellwig:
"A huge update this time, but a lot of that is just consolidating or
removing code:
- provide a common DMA_MAPPING_ERROR definition and avoid indirect

- use direct calls for the DMA direct mapping case, avoiding huge
retpoline overhead for high performance workloads
- merge the swiotlb dma_map_ops into dma-direct
- provide a generic remapping DMA consistent allocator for
architectures that have devices that perform DMA that is not cache
coherent. Based on the existing arm64 implementation and also used
for csky now.
- improve the dma-debug infrastructure, including dynamic allocation
of entries (Robin Murphy)
- default to providing chaining scatterlist everywhere, with opt-outs
for the few architectures (alpha, parisc, most arm32 variants) that
can't cope with it
- misc sparc32 dma-related cleanups
- remove the dma_mark_clean arch hook used by swiotlb on ia64 and
replace it with the generic noncoherent infrastructure
- fix the return type of dma_set_max_seg_size (Niklas Söderlund)
- move the dummy dma ops for not DMA capable devices from arm64 to
common code (Robin Murphy)
- ensure dma_alloc_coherent returns zeroed memory to avoid kernel

Pull arm64 festive updates from Will Deacon:
"In the end, we ended up with quite a lot more than I expected:
- Support for ARMv8.3 Pointer Authentication in userspace (CRIU and
kernel-side support to come later)
- Support for per-thread stack canaries, pending an update to GCC
that is currently undergoing review
- Support for kexec_file_load(), which permits secure boot of a kexec
payload but also happens to improve the performance of kexec
dramatically because we can avoid the sucky purgatory code from
userspace. Kdump will come later (requires updates to libfdt).
- Optimisation of our dynamic CPU feature framework, so that all
detected features are enabled via a single stop_machine()
invocation
- KPTI whitelisting of Cortex-A CPUs unaffected by Meltdown, so that
they can benefit from global TLB entries when KASLR is not in use
- 52-bit virtual addressing for userspace (kernel remains 48-bit)
- Patch in LSE atomics for per-cpu atomic operations
- Custom preempt.h implementation to avoid unconditional calls to
preempt_schedule() from preempt_enable()
- Support for the new 'SB' Speculation Barrier instruction
- Vectorised implementation of XOR checksumming and CRC32
optimisations
- Workaround for Cortex-A76 erratum #1165522
- Improved compatibility with Clang/LLD
- Support for TX2 system PMUS for profiling the L3 cache and DMC
- Reflect read-only permissions in the linear map by default
- Ensure MMIO reads are ordered with subsequent calls to Xdelay()
- Initial support for memory hotplug
- Tweak the threshold when we invalidate the TLB by-ASID, so that
mremap() performance is improved for ranges spanning multiple PMDs.
- Minor refactoring and cleanups"

Pull regulator updates from Mark Brown:
"This has been a very busy release for the core, some fixes, one large
new feature and a big bit of refactoring to update the GPIO API:
- Support for coupled regulators from Dmitry Osipenko based on a
prior attempt by Maciej Purski, allowing us to handle situations
where the voltages on two regulators can't be too far apart from
each other.
- Conversion of the GPIO support in both drivers and the core to use
GPIO descriptors rather than numbers, part of the overall project
to remove GPIO numbers.
- Support for standby mode suspend states from Andrei Stefanescu.
- New drivers for Allwinner AXP209, Cirrus Logic Lochnagar and
Microchip MPC16502"
