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.

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.

A make defconfig && make savedefconfig was performed for each

Most changes are due to options moving around, except for the following
which are due to changing defaults:
- SECCOMP is enabled by default as of commit 282a181b1a ("seccomp:
Move config option SECCOMP to arch/Kconfig") in v5.9
- 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

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In each case except Omicron, the board has been replaced by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.

Qualcomm dts updates for v5.15
This introduces the MSM8226 platform and an initial dts for the Samsung
Galaxy S III Neo phone.
MSM8974 gains another UART and this is used to enable Bluetooth on the
Sony Xperia Z2 Tablet. Samsung Galaxy S5 gains regulator definitions for
audio and modem remoteprocs, effectively enabling these.
DSI clocks on APQ8064 are updates as the old legacy clock names are no
longer supported by the driver. And IPQ806x GMAC nodes gains AHB resets
wired up.
Lastly APQ8060 is converted to a SPDX header and the ethernet node is
updates in accordance with the binding.
