@mknyszek requested issue #47505 to be considered for backport to the next 1.16 minor release.
@gopherbot Please open a backport issues for 1.15 and 1.16.
This bug is not new and can cause deadlocks on linux/arm (GOARM=6) when profiling is turned on with no workaround. The biggest immediate issue for us is that this will cause new failures on all release builders, if not fixed.

… helpers
On Linux ARMv6 and below runtime/internal/atomic.Cas calls into a kernel
cas helper at a fixed address. If a SIGPROF arrives while executing the
kernel helper, the sigprof lostAtomic logic will miss that we are
potentially in the spinlock critical section, which could cause
a deadlock when using atomics later in sigprof.
