XIP depends on MMU, but XIP_FIXUP is used throughout the kernel in
order to avoid excessive ifdefs. This just makes sure to always define
XIP_FIXUP, which will fix MMU=n builds. XIP_OFFSET is used by assembly
but XIP_FIXUP is C-only, so they're split.

LANG gives a weak default to each LC_* in case it is not explicitly
defined. LC_ALL, if set, overrides all other LC_* variables.
LANG < LC_CTYPE, LC_COLLATE, LC_MONETARY, LC_NUMERIC, ... < LC_ALL
This is why documentation such as [1] suggests to set LC_ALL in build
scripts to get the deterministic result.
LANG=C is not strong enough to override LC_* that may be set by end
users.

Currently, -Wunused-but-set-variable is only supported by GCC so it is
disabled unconditionally in a GCC only block (it is enabled with W=1).
clang currently has its implementation for this warning in review so
preemptively move this statement out of the GCC only block and wrap it
with cc-disable-warning so that both compilers function the same.

We maintain .gitignore and Makefiles so build artifacts are properly
ignored by Git, and cleaned up by 'make clean'. However, the code is
always changing; generated files are often moved to another directory,
or removed when they become unnecessary. Such garbage files tend to be
left over in the source tree because people usually git-pull without
cleaning the tree.
This is not only the noise for 'git status', but also a build issue
in some cases.
One solution is to remove a stale file like commit 223c24a7dba9 ("kbuild:
Automatically remove stale <linux/version.h> file") did. Such workaround
should be removed after a while, but we forget about that if we scatter
the workaround code in random places.
So, this commit adds a new script to collect cleanings of stale files.
As a start point, move the code in arch/arm/boot/compressed/Makefile
into this script.

If the timestamp of the .config file is updated, config_data.gz is
regenerated, then vmlinux is re-linked. This occurs even if the content
of the .config has not changed at all.
This issue was mitigated by commit 67424f61f813 ("kconfig: do not write
.config if the content is the same"); Kconfig does not update the
.config when it ends up with the identical configuration.
The issue is remaining when the .config is created by *_defconfig with
some config fragment(s) applied on top.
This is typical for powerpc and mips, where several *_defconfig targets
are constructed by using merge_config.sh.
One workaround is to have the copy of the .config. The filechk rule
updates the copy, kernel/config_data, by checking the content instead
of the timestamp.
With this commit, the second run with the same configuration avoids
the needless rebuilds.

We register the simplekms device with the DRM platform helpers. A
native driver for the graphics hardware will kick-out the simpledrm
driver before taking over the device.
The original generic platform device from the simple-framebuffer boot
code will be unregistered. The native driver will use whatever native
hardware device it received.
v4:
* convert to drm_aperture_acquire_from_firmware()
v3:
* use platform_device_unregister() and handle detachment
like hot-unplug event (Daniel)
v2:
* adapt to aperture changes
* use drm_dev_unplug() and drm_dev_enter/exit()
* don't split error string

The simpledrm driver is a DRM driver for simple-framebuffer framebuffers
as provided by the kernel's boot code. This driver enables basic
graphical output on many different graphics devices that are provided
by the platform (e.g., EFI, VESA, embedded framebuffers).
With the kernel's simple-framebuffer infrastructure, the kernel receives
a pre-configured framebuffer from the system (i.e., firmware, boot
loader). It creates a platform device to which simpledrm attaches.
The system's framebuffer consists of a memory range, size and format.
Based on these values, simpledrm creates a DRM devices. No actual
modesetting is possible.
A firmware framebuffer might also be specified via device-tree files. If
no device platform data is given, try the DT device node.
Make sure required hardware clocks and regulators are enabled while the
firmware framebuffer is in use. The basic code has been taken from the
simplefb driver and adapted to DRM. Clocks are released automatically
via devres helpers.
The drivers displays a console on simpledrm's framebuffer. The default
framebuffer format is being used.
v4:
* disable simplefb if simpledrm has been selected (Maxime)
v3:
* add disable function that clears screen to black (Daniel)
* set shadow buffering only for fbdev emulation
* set platform-driver data during device creation
v2:
* rename driver to simpledrm
* add dri-devel to MAINTAINERS entry
* put native format first in primary-plane format list (Daniel)
* inline simplekms_device_cleanup() (Daniel)
* use helpers for shadow-buffered planes
* fix whitespace errors
* add Device Tree match table
* clean-up parser wrappers
* use strscpy()

Platform devices might operate on firmware framebuffers, such as VESA or
EFI. Before a native driver for the graphics hardware can take over the
device, it has to remove any platform driver that operates on the firmware
framebuffer. Aperture helpers provide the infrastructure for platform
drivers to acquire firmware framebuffers, and for native drivers to remove
them later on.
It works similar to the related fbdev mechanism. During initialization, the
platform driver acquires the firmware framebuffer's I/O memory and provides
a callback to be removed. The native driver later uses this information to
remove any platform driver for it's framebuffer I/O memory.
The aperture removal code is integrated into the existing code for removing
conflicting framebuffers, so native drivers use it automatically.
v5:
* fix build error introduced by rebasing v4
* fix typo in documentation
v4:
* hide detach callback in implementation (Daniel)
* documentation fixes
v3:
* rebase onto existing aperture infrastructure
* release aperture from list during detach; fix dangling apertures
* don't export struct drm_aperture
* document struct drm_aperture_funcs
v2:
* rename plaform helpers to aperture helpers
* tie to device lifetime with devm_ functions
* removed unsued remove() callback
* rename kickout to detach
* make struct drm_aperture private
* rebase onto existing drm_aperture.h header file
* use MIT license only for simplicity
* documentation

sctp: always send a chunk with the asoc that it belongs to
Currently when processing a duplicate COOKIE-ECHO chunk, a new temp

However, later on it uses the old asoc to send these chunks, which
has caused quite a few issues.
This patchset is to fix this and make sure that the COOKIE-ACK and

There's a panic that occurs in a few of envs, the call trace is as below:
[] general protection fault, ... 0x29acd70f1000a: 0000 [#1] SMP PTI
[] RIP: 0010:sctp_ulpevent_notify_peer_addr_change+0x4b/0x1fa [sctp]

[] sctp_do_sm+0xc3/0x2a0 [sctp]
[] sctp_generate_timeout_event+0x81/0xf0 [sctp]
This is caused by a transport use-after-free issue. When processing a
duplicate COOKIE-ECHO chunk in sctp_sf_do_dupcook_a(), both COOKIE-ACK
and SHUTDOWN chunks are allocated with the transort from the new asoc.
However, later in the sideeffect machine, the old asoc is used to send
them out and old asoc's shutdown_last_sent_to is set to the transport
that SHUTDOWN chunk attached to in sctp_cmd_setup_t2(), which actually
belongs to the new asoc. After the new_asoc is freed and the old asoc
T2 timeout, the old asoc's shutdown_last_sent_to that is already freed
would be accessed in sctp_sf_t2_timer_expire().
Thanks Alexander and Jere for helping dig into this issue.
To fix it, this patch is to do the asoc update first, then allocate
the COOKIE-ACK and SHUTDOWN chunks with the 'updated' old asoc. This
would make more sense, as a chunk from an asoc shouldn't be sent out
with another asoc. We had fixed quite a few issues caused by this.

If selftest and reset are performed at the same time, the phy
loopback setting may be still in enable state after the reset,
and device cannot link up. So fix this issue by disabling phy
loopback before phy_start().

HW error and global reset are reported through MSIX interrupts.
The same error may be reported to different functions at the
same time. When global reset begins, the pending reset request
set by this error is unnecessary. So clear the pending reset
request after the reset is complete to avoid the repeated reset.

Currently, netif_tx_stop_all_queues() is used to ensure that
the xmit is not running, but for the concurrent case it will
not take effect, since netif_tx_stop_all_queues() just sets
a flag without locking to indicate that the xmit queue(s)
should not be run.
So use netif_tx_disable() to replace netif_tx_stop_all_queues(),
it takes the xmit queue lock while marking the queue stopped.

When skb->ip_summed is CHECKSUM_PARTIAL, for non-tunnel udp packet,
which has a dest port as the IANA assigned, the hardware is expected
to do the checksum offload, but the hardware whose version is below
V3 will not do the checksum offload when udp dest port is 4790.
So fixes it by doing the checksum in software for this case.

An issue found when network interface is down and up again, FPE handshake
fails to trigger. This is due to __FPE_REMOVING bit remains being set in
stmmac_fpe_stop_wq() but not cleared in stmmac_fpe_start_wq(). This
cause FPE workqueue task, stmmac_fpe_lp_task() not able to be executed.
To fix this, add clearing __FPE_REMOVING bit in stmmac_fpe_start_wq().

In commit 3235b0f20a0a ("drm/panel: panel-simple: Use runtime pm to
avoid excessive unprepare / prepare") we started using pm_runtime, but
my patch neglected to add the proper pm_runtime_disable(). Doh! Add
them now.

Pull pin control updates from Linus Walleij:
"There is a lot going on!
Core changes:
- A semantic change to handle pinmux and pinconf in explicit order
while up until now we depended on the semantic order in the device
tree. The device tree is a functional programming language and does
not imply any order, so the right thing is for the pin control core
to provide these semantics.
- Add a new pinmux-select debugfs file which makes it possible to go
in and select functions for a pin manually (iteratively, at the
prompt) for debugging purposes.
- Fixes to gpio regmap handling for a new pin control driver making
use of regmap-gpio.
- Use octal permissions on debugfs files.
New drivers:
- A massive rewrite of the former custom pin control driver for MIPS
Broadcom devices to instead use the pin control subsystem. New pin
control drivers for BCM6345, BCM6328, BCM6358, BCM6362, BCM6368,
BCM63268 and BCM6318 SoC variants are implemented.
- Support for PM8350, PM8350B, PM8350C, PMK8350, PMR735A and PMR735B
in the Qualcomm PMIC GPIO driver. Also the two GPIOs on PM8008 are
supported.
- Support for the Rockchip RK3568/RK3566 pin controller.
- Support for Ingenic JZ4730, JZ4750, JZ4755, JZ4775 and X2000.
- Support for Mediatek MTK8195.
- Add a new Xilinx ZynqMP pin control driver.
Driver improvements and non-urgent fixes:
- Modularization and improvements of the Rockchip drivers.
- Some new pins added to the description of new Renesas SoCs.
- Clarifications of the GPIO base calculation in the Intel driver.
- Fix the function names for the MPP54 and MPP55 pins in the Armada
CP110 pin controller.
- GPIO wakeup interrupt map for Qualcomm SC7280 and SM8350.
- Support for ACPI probing of the Qualcomm SC8180x.
- Fix interrupt clear status on rockchip
- Fix some missing pins on the Ingenic JZ4770, some semantic fixes
for the behaviour of the Ingenic pin controller. Add DMIC pins for
JZ4780, X1000, X1500 and X1830.
- A slew of janitorial like of_node_put() calls"

Pull sound updates from Takashi Iwai:
"No surprises in this development cycle, and most of work is about the
fixes and the improvements of the existing code, while a new LED
control layer and a few new drivers have been introduced.
Here are some highlights:
Core:
- A common mute-LED framework was introduced. It is used by HD-audio
for now, more adaption will follow later. The former "Mic Mute-LED
Mode" mixer control has been replaced with the corresponding sysfs
now.
- User-control management was changed to count consumed bytes instead
of capping by number of elements; this will allow more controls in
the normal usage pattern while avoiding the possible memory
exhaustion DoS
ASoC:
- Continued refactoring and cleanups in ASoC core and generic card
drivers
- Wide range of small cppcheck and warning fixes
- New drivers for Freescale i.MX DMA over rpmsg, Mediatek MT6358
accessory detection, and Realtek RT1019, RT1316, RT711 and RT715
USB-audio:
- Continued improvements and fixes of the implicit feedback mode,
including better support for Pioneer and Roland/BOSS devices
HD-audio:
- Default back to non-buffer preallocation on x86
- Cirrus codec improvements, more quirks for Realtek codecs
Others:
- New virtio sound driver
- FireWire Bebob updates"
