c1558bc57b8e5b4da5d821537cd30e2e660861d8 | Analyze and fix the following issue in the Linux kernel code: gcov: add support for GCC 14 | Problem Details:
Using gcov on kernels compiled with GCC 14 results in truncated 16-byte
long .gcda files with no usable data. To fix this, update GCOV_COUNTERS
to match the value defined by GCC 14.
Tested with GCC versions 14.1.0 and 13.2.0.

kernel_wait4() doesn't sleep and returns -EINTR if there is no
eligible child and signal_pending() is true.
That is why zap_pid_ns_processes() clears TIF_SIGPENDING but this is not
enough, it should also clear TIF_NOTIFY_SIGNAL to make signal_pending()
return false and avoid a busy-wait loop.
