None. The ticket is more general. It's about mcode allocation problem
due to address range limitation.

Updated the commit description.

Updated commit message:

test: disabled flaky test for macOS/ARM64

The test `fix-mips64-spare-side-exit-patching.test.lua`
is flaky on macOS and ARM64.

The problem is in the limited range for mcode chunk's
addresses on ARM64 and in the macOS strategy for `mmap`
to ignore user's hint. See [1] for details.

After the solution for the address range limitation problem
will be applied, the test must be reenabled.
