[PATCH v1 0/7] Various fixes for memory leaks introduced by Object Attributes v2 patch series

[Matthieu Longo]

This patch series contains fixes for memory-related issues.

The first five patches resolve new memory leaks introduced by the Object Attributes v2 patch series, in both generic and AArch64-specific code.
The sixth patch resolves a buffer overflow causing aarch64-gen to abort with ASAN runtime and ASAN_OPTIONS="abort_on_error=1".
And the last patch resolves age-old memory leaks in AArch64 GAS backend spamming LeakSanitizer reports.

Adding also Nick Clifton in CC as he might want to merge those patches on branch 2.46.

Regards,
Matthieu
