Hence __div64_const32_is_OK() is always true.

Moreover, __div64_const32_is_OK() is defined in the same way in
include/asm-generic/div64.h, so the ARM-specific definition can be

da0b9ee43c ARM: 9110/1: oabi-compat: fix oabi epoll sparse warning
As my patches change the oabi epoll definition, I received a report
from the kernel test robot about a pre-existing issue with a mismatched
__poll_t type.

The OABI code was correct when it was initially added in linux-2.16,
but a later (also correct) change to the generic __poll_t triggered a
type mismatch warning from sparse.

As __poll_t is always 32-bit bits wide and otherwise compatible, using
this instead of __u32 in the oabi_epoll_event definition is a valid
workaround.

8ac6f5d7f8 ARM: 9113/1: uaccess: remove set_fs() implementation
There are no remaining callers of set_fs(), so just remove it
along with all associated code that operates on
thread_info->addr_limit.

There are still further optimizations that can be done:

- In get_user(), the address check could be moved entirely
  into the out of line code, rather than passing a constant
  as an argument,

- I assume the DACR handling can be simplified as we now
  only change it during user access when CONFIG_CPU_SW_DOMAIN_PAN
  is set, but not during set_fs().

2df4c9a741 ARM: 9112/1: uaccess: add __{get,put}_kernel_nofault
These mimic the behavior of get_user and put_user, except
for domain switching, address limit checking and handling
of mismatched sizes, none of which are relevant here.

To work with pre-Armv6 kernels, this has to avoid TUSER()
inside of the new macros, the new approach passes the "t"
string along with the opcode, which is a bit uglier but
avoids duplicating more code.

As there is no __get_user_asm_dword(), I work around it
by copying 32 bit at a time, which is possible because
the output size is known.

bdec014528 ARM: 9114/1: oabi-compat: rework sys_semtimedop emulation
sys_oabi_semtimedop() is one of the last users of set_fs() on Arm. To
remove this one, expose the internal code of the actual implementation
that operates on a kernel pointer and call it directly after copying.

There should be no measurable impact on the normal execution of this
function, and it makes the overly long function a little shorter, which
may help readability.

While reworking the oabi version, make it behave a little more like
the native one, using kvmalloc_array() and restructure the code
flow in a similar way.

The naming of __do_semtimedop() is not very good, I hope someone can
come up with a better name.

One regression was spotted by kernel test robot <rong.a.chen@intel.com>
and fixed before the first mailing list submission.

249dbe74d3 ARM: 9108/1: oabi-compat: rework epoll_wait/epoll_pwait emulation
The epoll_wait() system call wrapper is one of the remaining users of
the set_fs() infrasturcture for Arm. Changing it to not require set_fs()
is rather complex unfortunately.

The approach I'm taking here is to allow architectures to override
the code that copies the output to user space, and let the oabi-compat
implementation check whether it is getting called from an EABI or OABI
system call based on the thread_info->syscall value.

The in_oabi_syscall() check here mirrors the in_compat_syscall() and
in_x32_syscall() helpers for 32-bit compat implementations on other
architectures.

Overall, the amount of code goes down, at least with the newly added
sys_oabi_epoll_pwait() helper getting removed again. The downside
is added complexity in the source code for the native implementation.
There should be no difference in runtime performance except for Arm
kernels with CONFIG_OABI_COMPAT enabled that now have to go through
an external function call to check which of the two variants to use.

4e57a4ddf6 ARM: 9107/1: syscall: always store thread_info->abi_syscall
The system call number is used in a a couple of places, in particular
ptrace, seccomp and /proc/<pid>/syscall.

The last one apparently never worked reliably on ARM for tasks that are
not currently getting traced.

Storing the syscall number in the normal entry path makes it work,
as well as allowing us to see if the current system call is for OABI
compat mode, which is the next thing I want to hook into.

Since the thread_info->syscall field is not just the number any more, it
is now renamed to abi_syscall. In kernels that enable both OABI and EABI,
the upper bits of this field encode 0x900000 (__NR_OABI_SYSCALL_BASE)
for OABI tasks, while normal EABI tasks do not set the upper bits. This
makes it possible to implement the in_oabi_syscall() helper later.

All other users of thread_info->syscall go through the syscall_get_nr()
helper, which in turn filters out the ABI bits.

Note that the ABI information is lost with PTRACE_SET_SYSCALL, so one
cannot set the internal number to a particular version, but this was
already the case. We could change it to let gdb encode the ABI type along
with the syscall in a CONFIG_OABI_COMPAT-enabled kernel, but that itself
would be a (backwards-compatible) ABI change, so I don't do it here.

b6e47f3c11 ARM: 9109/1: oabi-compat: add epoll_pwait handler
The epoll_wait() syscall has a special version for OABI compat
mode to convert the arguments to the EABI structure layout
of the kernel. However, the later epoll_pwait() syscall was
added in arch/arm in linux-2.6.32 without this conversion.

Use the same kind of handler for both.

344179fc7e ARM: 9106/1: traps: use get_kernel_nofault instead of set_fs()
ARM uses set_fs() and __get_user() to allow the stack dumping code to
access possibly invalid pointers carefully. These can be changed to the
simpler get_kernel_nofault(), and allow the eventual removal of set_fs().

dump_instr() will print either kernel or user space pointers,
depending on how it was called. For dump_mem(), I assume we are only
interested in kernel pointers, and the only time that this is called
with user_mode(regs)==true is when the regs themselves are unreliable
as a result of the condition that caused the trap.

which are due to changing defaults:

 - SECCOMP is enabled by default as of commit 282a181b1a ("seccomp:

 - The soc drivers ASPEED_LPC_CTRL, ASPEED_LPC_SNOOP and ASPEED_P2A_CTRL
   are enabled by default when the aspeed platform is enabled, as of
   commit 592693a1f8 ("soc: aspeed: Improve kconfig") in v5.9

 - The ZBOOT_ROM_TEXT/BSS values fall out of the defconfig as of
   commit 39c3e30456 ("ARM: 8984/1: Kconfig: set default
   ZBOOT_ROM_TEXT/BSS value to 0x0") in v5.8

 - I2C_MUX is selected by MEDIA_SUBDRV_AUTOSELECT, probably as of about
   v5.8. It was in the config as it is required bt the PCA I2C muxes
   that enabled it

 - Arcom Vulcan
 - Avila
 - Intel reference designs
 - Coyote and IXDPG425

 In each case except Omicron, the board has been replaced by
 a corresponding device tree and tested where someone
 volunteered: Marc Zyngier has tested Arcom Vulcan and Freecom
 FSG-3 and I have tested NSLU2 and Avila for example. All
 that were tested boot to prompt, some devices may need some
 more massage before working perfectly.
 
 We can just as well delete these board files because we are
 confident that we will fix them to a working state if people
 are able to test patches.
 
 I am holding back the following boards for now:
 
 - Gateway 7001 - because Zoltan is working on this board and
   needs more time. He might need to test things with the board
   file so let's allow him time for that.
 
 - Goramo MLR - the consensus is to replace this with a dry
   coded device tree, but the bindings for that tree need some
   more time to make so we keep the boardfile around until
   we can merge a complete device tree for it.
 
 After these two (target v5.16) we can delete the remaining
 board files and the old mach structure along with the old PCI
 driver.

Merge tag 'ixp4xx-del-boardfiles-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik into arm/soc

This deletes the following IXP4xx boardfiles:

- NSLU2
- NAS100D
- D-Link DSM-G600
- Omicron
- Gateway WG302v2
- Arcom Vulcan
- Avila
- Intel reference designs
- Coyote and IXDPG425
- GTW5715
- Freecom FSG-3

In each case except Omicron, the board has been replaced by
a corresponding device tree and tested where someone
volunteered: Marc Zyngier has tested Arcom Vulcan and Freecom
FSG-3 and I have tested NSLU2 and Avila for example. All
that were tested boot to prompt, some devices may need some
more massage before working perfectly.

We can just as well delete these board files because we are
confident that we will fix them to a working state if people
are able to test patches.

I am holding back the following boards for now:

- Gateway 7001 - because Zoltan is working on this board and
  needs more time. He might need to test things with the board
  file so let's allow him time for that.

- Goramo MLR - the consensus is to replace this with a dry
  coded device tree, but the bindings for that tree need some
  more time to make so we keep the boardfile around until
  we can merge a complete device tree for it.

After these two (target v5.16) we can delete the remaining
board files and the old mach structure along with the old PCI
driver.

b528dede9b AT91 defconfig for 5.15:
- add defconfig entries for new SoC: SAMA7G5
   - dedicated sama7_defconfig which avoids having to carry older drivers
     and dependencies from the sama5 family:
     CACHE_L2X0, CAN_AT91, TOUCHSCREEN_ADC, AT91SAM9X_WATCHDOG,
     VIDEO_ATMEL_ISI, SND_ATMEL_SOC_I2S, MMC_ATMELMCI, AT_HDMAC, AT91_ADC,
     REGULATOR_ACT*
     Addition of new drivers that are not part of any sama5 SoC:
     SND_MCHP_SOC_I2S_MCC, SND_MCHP_SOC_SPDIFTX|RX, MICROCHIP_PIT64B
     plus upcoming MIPI pipeline, audio sample rate converter, ...
     It also maintains both sama5 and sama7 defconfig tailored for their
     respective families and easy to identify.
   - addition to the generic multi_v7_defconfig

b30d0289de ARM: 9105/1: atags_to_fdt: don't warn about stack size
The merge_fdt_bootargs() function by definition consumes more than 1024
bytes of stack because it has a 1024 byte command line on the stack,
meaning that we always get a warning when building this file:

arch/arm/boot/compressed/atags_to_fdt.c: In function 'merge_fdt_bootargs':
arch/arm/boot/compressed/atags_to_fdt.c:98:1: warning: the frame size of 1032 bytes is larger than 1024 bytes [-Wframe-larger-than=]

However, as this is the decompressor and we know that it has a very shallow
call chain, and we do not actually risk overflowing the kernel stack
at runtime here.

This just shuts up the warning by disabling the warning flag for this
file.

Tested on Nexus 7 2012 builds.

463dbba4d1 ARM: 9104/2: Fix Keystone 2 kernel mapping regression
This fixes a Keystone 2 regression discovered as a side effect of
defining an passing the physical start/end sections of the kernel
to the MMU remapping code.

As the Keystone applies an offset to all physical addresses,
including those identified and patches by phys2virt, we fail to
account for this offset in the kernel_sec_start and kernel_sec_end
variables.

Further these offsets can extend into the 64bit range on LPAE
systems such as the Keystone 2.

Fix it like this:
- Extend kernel_sec_start and kernel_sec_end to be 64bit
- Add the offset also to kernel_sec_start and kernel_sec_end

As passing kernel_sec_start and kernel_sec_end as 64bit invariably
incurs BE8 endianness issues I have attempted to dry-code around
these.

Tested on the Vexpress QEMU model both with and without LPAE
enabled.

00342c631e ARM: dts: imx6q-dhcom: Rework of the DHCOM GPIO pinctrls
The function of each SoM pins is defined in the DHCOM standard [1] and
subset of them is defined as GPIOs (pins A-W). To ensure the interchange-
ability of the DHCOM SoMs, the function of the pins are fixed and cannot
be changed. On board level the DHCOM GPIOs can be used associated with
different blocks e.g. for interrupt or reset, but the function is always
GPIO. If not used, they can be freely used in the user space.

Therefore the whole configuration of SoM pins is made in the SoM DT.
Defining the DHCOM GPIO pins as a separate pinctrl nodes makes moving a
subset of them to an appropriate block pinctrl group easier on board level,
since it is not necessary to have a large pinctrl hog group containing
unrelated pinmux entries on board level. This also makes it easy to update
the SoM DT without having to update all the board DTs too. If necessary it
is also possible to change the electrical properties of the DHCOM GPIOs by
overwriting the pinctrl on board level.

298591bf72 ARM: dts: imx6q-dhcom: Use 1G ethernet on the PDK2 board
The PDK2 board is capable of running both 100M and 1G ethernet. However,
the i.MX6 has only one ethernet MAC, so it is possible to configure
either 100M or 1G Ethernet. In case of 100M option, the PHY is on the
SoM and the signals are routed to a RJ45 port. For 1G the PHY is on
the PDK2 board with another RJ45 port. 100M and 1G ethernet use
different signal pins from the i.MX6, but share the MDIO bus.

This SoM board combination is used to demonstrate how to enable 1G
ethernet configuration.
