462de189b0 arm64: boot: secondaries: ensure WFI doesn't trap 
The WFI insn is set not to trap on the primary core. Ensure it's also
set on the secondary cores too.

ba53418382 arm64: secondary: ensure boot_ctx is flushed to RAM 
When the secondary boots and derefes the boot_ctx pointer passed in as a
parameter, it reads NULL, causing the secondary to end up stuck in an
exception loop. The data is sat in the primary core's cache and hasn't
been flushed to RAM. Since the secondary starts without the MMU (and
caches) enabled, the CCI doesn't kick in and we read stale data.

Manually flush the boot_ctx data to RAM before waking up the secondary.

d92945379a arm64: memory: flush_to_ram: new 
Create a new function which takes a pointer to an object `T` and ensures
that the data is flushed from the caches to the point of
coherency (RAM).

fae5dc1a4f usertest: fix test output 
Since the test driver now outputs the test name, remove test name
printing in the signal tests.

Also flush stdout when the test has began running so if a problem
occures it's easier to know which test was running.

4a3477182a clock_nanosleep: fix arguments to syscall 
The `sys_clock_nanosleep` implementation was missing a `flags` parameter
in the second position.  This meant that `rqtp` was interpreted as
`rmtp`, and when interrupted, `rmtp` would write to a garbage address
causing an `EFAULT`.

Fix the argument ordering.

3b71fa3d39 signal: interruptible: prioritize wrapped future over signals 
Poll the wrapped future first, ensuring that the interrupt logic doesn't
short-circuit a future which is already ready.

This fixes an issue where `sys_wait4` would return `-EINTR` when
receiving a `SIGCHLD`. Since `SIGCHLD` indicates the wait condition
is met, the underlying future is ready and should return the PID
successfully rather than aborting.

ecdfd360d1 sched: remove force_resched() 
This function is used to force the scheduler to reschedule another task,
avoiding the fast-path exit.  Given the sheer number of task state
change points in the code, the fast-path exit code has become too
brittle.

Instead, check that the current task's state is still `Running` before
taking the fast-path short-circuit. The cost of one spinlock uncontended
lock-unlock cycle is worth the cost of avoiding many subtle scheduling
logic bugs.

4a88739804 syscalls: tty: read: make interruptable() 
Allow a `read()` on a tty to be interrupted by a syscall. This is the
fundamental fix for making '^C' interrupt a process like `cat` when it's
reading from `stdin`.
