Most Kirkwood boards use the default SPI0 pinctrl setting anyway. Add a
default pinctrl setting to the toplevel SoC SPI0 node and put a note
in front of the corresponding pinctrl node to overwrite the setting
on board level.
Currently, only T5325 is using a different setting and already
overwrites the corresponding pinctrl node.

Most boards use the default UART0/1 pinctrl setting without RTS/CTS.
Add the pinctrl setting to the toplevel SoC UART nodes and put a note
in front of the corresponding pinctrl node to overwrite the setting
on board level. Currently, both boards using a different UART pinctrl
setting (Openblocks A6, A7) already overwrite the pinctrl node.

All Kirkwood SoCs have their pinctrl registers at the same address.
Instead of replaying the same reg property on each SoC, have the

The Netgear RN2120 was not using the same strategy as the other Armada
370/375/38x/XP boards: it was using a 'clocks' property and not the
'clock-frequency' property in its UART controller Device Tree node.
However, now that this clock reference is present at the SoC-level,
there is no point in duplicating it at the board-level.

Now that the Armada 370/375/38x/XP SoC-level Device Tree files have

Back when the Armada 370 and Armada XP initial support was introduced,
the only way to pass the clock frequency to the of_serial driver was
through a clock-frequency Device Tree property.
Thanks to 0bbeb3c3e8 ('of serial port
driver - add clk_get_rate() support'), it is possible to use the
standard 'clocks' DT property to reference the clock used for a
particular UART controller. This clock is then used by the of_serial
driver to retrieve the clock rate.
This commit modifies the SoC-level Device Tree files of Armada 370,
Armada XP, Armada 375 and Armada 38x to use this possibility. Since
there is no gatable clock for the UART controllers, we simply
reference the TCLK, which is the main SoC clock for the peripherals.

Following the introduction of the new PMSU Device Tree binding, as
well as the separate CPU reset binding, this commit switches the
Armada 370 and Armada XP Device Trees to use them.
The PMSU node is moved from the Armada XP specific armada-xp.dtsi to
the common Armada 370/XP armada-370-xp.dtsi because the PMSU is in
fact available at the same location on both SOCs.
The CPU reset node is then added on both Armada 370 and Armada XP,
with a different compatible string. On Armada 370, the CPU reset
driver is not really needed as Armada 370 is single core and the only
use of the CPU reset driver is to boot secondary processors, but it
still makes sense to have this CPU reset register described in the
Device Tree.

Commit 8f619b5429 ("powerpc/ppc64: Do not turn AIL (reloc-on
interrupts) too early") added code to set the AIL bit in the LPCR
without checking whether the kernel is running in hypervisor mode. The
result is that when the kernel is running as a guest (i.e., under
PowerKVM or PowerVM), the processor takes a privileged instruction
interrupt at that point, causing a panic. The visible result is that
the kernel hangs after printing "returning from prom_init".
This fixes it by checking for hypervisor mode being available before
setting LPCR. If we are not in hypervisor mode, we enable relocation-on
interrupts later in pSeries_setup_arch using the H_SET_MODE hcall.

Pullx86 core platform updates from Peter Anvin:
"This is the x86/platform branch with the objectionable IOSF patches
removed.
What is left is proper memory handling for Intel GPUs, and a change to
the Calgary IOMMU code which will be required to make kexec work
sanely on those platforms after some upcoming kexec changes"
* 'x86-platform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86, calgary: Use 8M TCE table size by default
x86/gpu: Print the Intel graphics stolen memory range
x86/gpu: Add Intel graphics stolen memory quirk for gen2 platforms
x86/gpu: Add vfunc for Intel graphics stolen memory base address
Pull x86 fixes from Peter Anvin:
"This is a collection of minor fixes for x86, plus the IRET information
leak fix (forbid the use of 16-bit segments in 64-bit mode)"
NOTE! We may have to relax the "forbid the use of 16-bit segments in
64-bit mode" part, since there may be people who still run and depend on
16-bit Windows binaries under Wine.
But I'm taking this in the current unconditional form for now to see who
(if anybody) screams bloody murder. Maybe nobody cares. And maybe
we'll have to update it with some kind of runtime enablement (like our
vm.mmap_min_addr tunable that people who run dosemu/qemu/wine already
need to tweak).
* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86-64, modify_ldt: Ban 16-bit segments on 64-bit kernels
efi: Pass correct file handle to efi_file_{read,close}
x86/efi: Correct EFI boot stub use of code32_start
x86/efi: Fix boot failure with EFI stub
x86/platform/hyperv: Handle VMBUS driver being a module

Pull second set of ARM changes from Russell King:
"This is the remainder of the ARM changes for this merge window.
Included in this request are:
- fixes for kprobes for big-endian support
- fix tracing in soft_restart
- avoid phys address overflow in kdump code
- fix reporting of read-only pmd bits in kernel page table dump
- remove unnecessary (and possibly buggy) call to outer_flush_all()
- fix a three sparse warnings (missing header file for function
prototypes)
- fix pj4 crashing single zImage (thanks to arm-soc merging changes
which enables this with knowledge that the corresponding fix had
not even been submitted for my tree before the merge window opened)
- vfp macro cleanups
- dump register state on undefined instruction userspace faults when
debugging"

The IRET instruction, when returning to a 16-bit segment, only
restores the bottom 16 bits of the user space stack pointer. We have
a software workaround for that ("espfix") for the 32-bit kernel, but
it relies on a nonzero stack segment base which is not available in
32-bit mode.
Since 16-bit support is somewhat crippled anyway on a 64-bit kernel
(no V86 mode), and most (if not quite all) 64-bit processors support
virtualization for the users who really need it, simply reject
attempts at creating a 16-bit segment when running on top of a 64-bit
kernel.

The only user of Kconfig symbol IP_CHECKSUM_L1 got removed in v2.6.33,
with commit ddf9ddacef ("Blackfin: convert
to generic checksum code"). We can remove the Kconfig entry for this
unused symbol now.

The Kconfig symbol GENERIC_GPIO was removed in v3.10. Nothing cares
about it anymore. It popped up somehow in v3.13, so it can be removed
again.
