Merge patch series "fix reading ESP during coredump"
Nam Cao <[email protected]> says:
In /proc/PID/stat, there is the kstkesp field which is the stack pointer of
a thread. While the thread is active, this field reads zero. But during a
coredump, it should have a valid value.
However, at the moment, kstkesp is zero even during coredump.
The first commit fixes this problem, and the second commit adds a selftest
to detect if this problem appears again in the future.
