Add the io_uring and pidfd_send_signal system calls to all architectures.
These system calls are designed to handle both native and compat tasks,
so all entries are the same across architectures, only arm-compat and

struct timex uses struct timeval internally.
struct timeval is not y2038 safe.
Introduce a new UAPI type struct __kernel_timex
that is y2038 safe.
struct __kernel_timex uses a timeval type that is
similar to struct __kernel_timespec which preserves the
same structure size
. They only add a few bytes of bloat, so it seems
better to keep them compared to adding yet another Kconfig symbol.

Arnd Bergmann (8):
time: make adjtime compat handling available for 32 bit
time: fix sys_timer_settime prototype
sparc64: add
rintuitive.
This is only a cleanup patch and it should not change any behavior.

-bit counterpart yet,
but these can all be safely implemented in the C library by wrapping
around the existing system calls because the 32-bit time_t they
pass only counts elapsed time, not time since the epoch. They
will be dealt with later.

and __kernel_timex can get removed with this.
It would be easy to split this commit by architecture, but with the new
generated system call tables, it's easy enough to do it all at once,
which makes it a little easier to check that the changes are the same
in each table.

From: Deepa Dinamani
struct timex uses struct timeval internally.
struct timeval is not y2038 safe.
Introduce a new UAPI type struct __kernel_timex
that is y2038 safe.
struct __kernel_timex uses a timeval type that is
similar to struct __kernel_timespec which preserves the
same structure size
A small typo has crept into the y2038 conversion of the timer_settime
system call. So far this was completely harmless, but once we start
using the new version, this has to be fixed.

struct timex is not y2038 safe.
Replace all uses of timex with y2038 safe __kernel_timex.
Note that struct __kernel_timex is an ABI interface definition.
We could define a new structure based on __kernel_timex that
is only available internally instead. Right now, there

__kernel_timespec and timespec are currently the same type, but once
they are different, the type cast has to be changed here.

All architectures should implement these two, so assign numbers
