Subject: [PATCH] check-namespace.sh: adjust aarch64 symbols
|

|

Some symbols for aarch64 were missing, and some were marked as
|

extraneous in this ABI checker.
|

|

Fixes #389.

Subject: [PATCH] tests/run-coredump-unwind: Skip test if no coredump has been
|

created
|
||||
|
||||
In some build environments, coredumps are not created even if the
|
||||
corresponding ulimit is positive. This change skips the test if
|

the coredump is missing.
