This series adds support for the TERES I open hardware laptop produced
by olimex. With these patches and a bootloader capable of setting up
simple framebuffer the laptop is quite useable.
Patches 1-4 add some pin descriptions and devices in the A64 dtsi, which
are useful to have on the teres.
Patc
Add a watchdog node for the A64, automatically enabled on all boards.
Tested on Olimex Teres I.

This patch fixes a corner case for KSM. When two pages belong or
belonged to the same transparent hugepage, and they should be merged,
KSM fails to split the page, and therefore no merging happens.

In certain cases interrupt enablement will be delayed relative to when

Using pr_() is more concise than printk(KERN_).

* Replace printks having a log level with the appropriate pr_*() macros.
* Define pr_fmt() to include relevant name.
* Remove redundant prefixes from pr_*() calls.

Can you please bisect this, manually if necessary? Let me know if you
need any help.

The series is a preparation series for individual architectures
to use 64 bit time_t syscalls in compat and 32 bit emulation modes.
This is a follow up to the series Arnd Bergmann posted:

Many of the compat time syscalls are also repurposed as 32 bit
native syscalls to provide backward compatibility while adding
new y2038 safe sycalls.
Enabling the helpers makes this possible.

Change over clock_nanosleep syscalls to use y2038 safe
__kernel_timespec times. This will enable changing over
of these syscalls to use new y2038 safe syscalls when
the architectures define the CONFIG_64BIT_TIME.
Note that nanosleep syscall is deprecated and does not have a
plan for making it y203
All the current architecture specific defines for these
are the same. Refactor these common defines to a common
header file.
The new common linux/compat_time.h is also useful as it
will eventually be used to hold all the defines that
are needed for compat time types that support non y2038
safe typ
get/put_timespec64() interfaces will eventually be used for
conversions between the new y2038 safe struct __kernel_timespec
and struct timespec64.
The new y2038 safe syscalls have a common entry for native

On compat interfaces, the high order bits of nanoseconds

These functions are used in the repurposed compat syscalls
to provide backward compatibility for using 32 bit time_t

Compat functions are now used to support 32 bit time_t in
compat mode on 64 bit architectures and in native mode on
32 bit architectures.
Introduce COMPAT_32BIT_TIME to conditionally compile these
functions.
Note that turning off 32 bit time_t support requires more
changes on architecture side. F
There are a total of 53 system calls (aside from ioctl) that pass a time_t
or derived data structure as an argument, and in order to extend time_t
to 64-bit, we have to replace them with new system calls and keep providing
backwards compatibility.
