Remove the reference to the obsolete kselftest wiki.

The kselftest wiki is marked obsolete and is no longer updated. The last
edit was in 2019, and the information is outdated, referring readers for
support to IRC networks that have not been used for years, and to kernel
versions that are no longer supported.

If there is any relevant information left in the wiki it needs to be
cleaned up and moved into the canonical kselftest documentation here.

 "Futex updates:

   - Optimize futex hash bucket access patterns (Peter Zijlstra)

   - Large series to address the robust futex unlock race for real, by
     Thomas Gleixner:

      "The robust futex unlock mechanism is racy in respect to the
       clearing of the robust_list_head::list_op_pending pointer because
       unlock and clearing the pointer are not atomic.

       The race window is between the unlock and clearing the pending op
       pointer. If the task is forced to exit in this window, exit will
       access a potentially invalid pending op pointer when cleaning up
       the robust list.

       That happens if another task manages to unmap the object
       containing the lock before the cleanup, which results in an UAF.

       In the worst case this UAF can lead to memory corruption when
       unrelated content has been mapped to the same address by the time
       the access happens.

       User space can't solve this problem without help from the kernel.
       This series provides the kernel side infrastructure to help it
       along:

        1) Combined unlock, pointer clearing, wake-up for the
           contended case

        2) VDSO based unlock and pointer clearing helpers with a
           fix-up function in the kernel when user space was interrupted
           within the critical section.

      ... with help by André Almeida:

        - Add a note about robust list race condition (André Almeida)
        - Add self-tests for robust release operations (André Almeida)

This is used by things like Jenkins and other CI systems, which can
pretty-print the test output and potentially provide test-level comparisons
between runs.

The implementation here is pretty basic: it only provides the raw results,
split into tests and test suites, and doesn't provide any overall metadata.
However, CI systems like Jenkins can ingest it and it is already useful.

The CONFIG_PROPELLER_CLANG option currently depends on
ARCH_SUPPORTS_PROPELLER_CLANG, but this dependency seems unnecessary.

Remove ARCH_SUPPORTS_PROPELLER_CLANG and allow users to control
Propeller builds solely through CONFIG_PROPELLER_CLANG. This simplifies
the kconfig and avoids potential confusion.

Move the .llvm_bb_addr_map sections grouping to
include/asm-generic/vmlinux.lds.h.

The Propeller documentation has been updated to reflect the most
recent tool location and now includes instructions for arm64.

Allow the same userspace thread to simultaneously collect normal coverage
in syscall context (KCOV_ENABLE) and remote coverage of asynchronous work
created by the thread (KCOV_REMOTE_ENABLE).  With this, remote KCOV
coverage becomes useful for generic fuzzing and not just fuzzing of
specific data injection interfaces.

This requires that the task_struct::kcov_* fields are separated into ones
that are used by the task that generates coverage, and ones that are used
by the task that requested remote coverage.  To split this up:

 - Split task_struct::kcov into kcov and kcov_remote. kcov_task_exit() now
   has to clean up both separately.
 - Only use task_struct::kcov_mode on the task that generates coverage.
 - Only reset task_struct::kcov_handle on the task that requested remote
   coverage.

After this change, fields used by the task that generates coverage are:

 - kcov_mode
 - kcov_size
 - kcov_area
 - kcov
 - kcov_sequence
 - kcov_softirq

Fields used by the task that requested remote coverage are:

 - kcov_remote
 - kcov_handle
