Rename _PFN_SHIFT to PFN_PTE_SHIFT. Convert a few places
to call set_pte() instead of set_pte_at(). Add set_ptes(),
update_mmu_cache_range(), flush_icache_pages() and flush_dcache_folio().
Change the PG_arch_1 (aka PG_dcache_dirty) flag from being per-page
to per-folio.Link: https://lkml.kernel.org/r/20230802151406.3735276-18-willy@infradead.org

Clang is especially sensitive about argument type matching when using

pointers are just "void *". Avoids this error:arch/mips/bcm47xx/prom.c:89:8: error: no matching function for call to 'memcmp'

If this option is not 0x0, it will be used for zboot load address.
Otherwise, the result of calc_vmlinuz_load_addr will be used.The zload-y value for generic are also removed then, as the current
value breaks booting on qemu -M boston.
The result of calc_vmlinuz_load_addr works well for most of cases.The default value of bcm47xx keeps as it currently.

The strlcpy should not be used because it doesn't limit the source
length. As linus says, it's a completely useless function if you
can't implicitly trust the source string - but that is almost always
why people think they should use it! All in all the BSD function
will lead some potential bugs.But the strscpy doesn't require reading memory from the src string
beyond the specified "count" bytes, and since the return value is
easier to error-check than strlcpy()'s. In addition, the implementation
is robust to the string changing out from underneath it, unlike the
current strlcpy() implementation.Thus, We prefer using strscpy instead of strlcpy.

The Netgear R6200 v1 uses a BCM4718A1 SOC and a BCM4352/BCM4360 for 5GHz
wireless. This patch adds support for detecting this model board and
registers the 3 buttons.I have tested that the device can boot kernels 4.14 and 4.19 under
OpenWRT.There is one issue that the LEDs on the device are controlled by a
74HC164 that uses bit-banging instead of SPI so it isn't accessible to
the kernel without adding a workaround. Without any workaround the
device on boot will flash all LEDs once then the power LED will remain
amber as all other LEDs stay off.Signed-off-by: Edward Matijevic

A small batch of MIPS fixes for 5.1:
- An interrupt masking fix for Loongson-based Lemote 2F systems (fixing
a regression from v3.19).- A relocation fix for configurations in which the devicetree is stored
in an ELF section (fixing a regression from v4.7).- Fix jump labels for MIPSr6 kernels where they previously could
inadvertently place a control transfer instruction in a forbidden slot
& take unexpected exceptions (fixing MIPSr6 support added in v4.0).- Extend an existing USB power workaround for the Netgear WNDR3400 to v2
boards in addition to the v3 ones that already used it.- Remove the custom MIPS32 definition of __kernel_fsid_t to make it
consistent with MIPS64 & every other architecture, in particular
resolving issues for code which tries to print the val field whose
type previously differed (though had identical memory layout).Merged into mips-next to gain the MIPSr6 jump label fix before enabling
jump labels by default for generic kernel builds.Signed-off-by: Paul Burton

All users of the fixed_phy_add() pass -1 as GPIO number
to the fixed phy driver, and all users of fixed_phy_register()
pass -1 as GPIO number as well, except for the device
tree MDIO bus.Any new users should create a proper device and pass the
GPIO as a descriptor associated with the device so delete
the GPIO argument from the calls and drop the code looking
requesting a GPIO in fixed_phy_add().In fixed phy_register(), investigate the "fixed-link"
node and pick the GPIO descriptor from "link-gpios" if
this property exists. Move the corresponding code out
of of_mdio.c as the fixed phy code anyways requires

So far we never had any device registered for the SoC. This resulted in
some small issues that we kept ignoring like:
1) Not working GPIOLIB_IRQCHIP (gpiochip_irqchip_add_key() failing)
2) Lack of proper tree in the /sys/devices/
3) mips_dma_alloc_coherent() silently handling empty coherent_dma_maskKernel 4.19 came with a lot of DMA changes and caused a regression on
bcm47xx. Starting with the commit f8c55dc6e828 ("MIPS: use generic dma

This reverts commit 2a027b47dba6 ("MIPS: BCM47XX: Enable 74K Core
ExternalSync for PCIe erratum").Enabling ExternalSync caused a regression for BCM4718A1 (used e.g. in
Netgear E3000 and ASUS RT-N16): it simply hangs during PCIe
initialization. It's likely that BCM4717A1 is also affected.I didn't notice that earlier as the only BCM47XX devices with PCIe I
own are:
1) BCM4706 with 2 x 14e4:4331
2) BCM4706 with 14e4:4360 and 14e4:4331
it appears that BCM4706 is unaffected.While BCM5300X-ES300-RDS.pdf seems to document that erratum and its
workarounds (according to quotes provided by Tokunori) it seems not even
Broadcom follows them.According to the provided info Broadcom should define CONF7_ES in their
SDK's mipsinc.h and implement workaround in the si_mips_init(). Checking
both didn't reveal such code. It *could* mean Broadcom also had some
problems with the given workaround.Signed-off-by: Rafał Miłecki

The erratum and workaround are described by BCM5300X-ES300-RDS.pdf as
below.R10: PCIe Transactions Periodically Fail
Description: The BCM5300X PCIe does not maintain transaction ordering.
This may cause PCIe transaction failure.
Fix Comment: Add a dummy PCIe configuration read after a PCIe
configuration write to ensure PCIe configuration access
ordering. Set ES bit of CP0 configu7 register to enable
sync function so that the sync instruction is functional.
Resolution: hndpci.c: extpci_write_config()
hndmips.c: si_mips_init()
mipsinc.h CONF7_ESThis is fixed by the CFE MIPS bcmsi chipset driver also for BCM47XX.
Also the dummy PCIe configuration read is already implemented in the
Linux BCMA driver.Enable ExternalSync in Config7 when CONFIG_BCMA_DRIVER_PCI_HOSTMODE=y
too so that the sync instruction is externalised.Signed-off-by: Tokunori Ikegami

This adds support for detecting this model board and registers some LEDs
and buttons.There are two uncommon things regarding this device:
1) It can use two different "board_id" ID values.
Unit I have uses "U12H139T00_NETGEAR" value. This magic is also used
in firmware file header. There are two reports (one from an OpenWrt
user) of a different "U12H139T50_NETGEAR" magic though.
2) Power LEDs share GPIOs with buttons.
Amber one seems to share GPIO 2 with WPS button and green one seems
to share GPIO 3 with reset button. It remains unknown how to support
them and handle buttons at the same time. For that reason they aren't
added to the list of supported LEDs.Signed-off-by: Rafał Miłecki

Some Luxul devices use PCIe connected GPIO LEDs that are not available
until the PCI subsytem and its drivers load. Using the same array for
these LEDs would block registering any LEDs until all GPIOs become
available. This may be undesired behavior as some LEDs should be
available as early as possible (e.g. system status LED). This patch will
allow registering available LEDs while deferring these PCIe GPIO
connected 'extra' LEDs until they become available.Signed-off-by: Dan Haab

Enable ZBOOT support. The WRT54GL router's bootloader limits kernel
size to 3 MB with the normal load address, which is a bit challenging
vmlinux size with modern Linux. A compressed kernel allows booting
much bigger kernels.Signed-off-by: Aaro Koskinen

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.By default all files without license information are under the default
license of the kernel, which is GPL version 2.Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if
