[PATCH rasdaemon 0/2] support l3tag&l3data decoding and one fix

[Xiaofei Tan]

This patch set does two things:
1.add decoding for two modules, l3tag and l3data.
2.fix the issue that non standard decoder can't work in pthread way.

t00396350 (2):
  rasdaemon: add support of l3tag and l3data in hip08 OEM format2
  rasdaemon: fix the issue that non standard decoder can't work in
    pthread way

[PATCH rasdaemon 1/2] rasdaemon: add support of l3tag and l3data in hip08 OEM format2

[Xiaofei Tan]

The two modules, l3tag and l3data were originally reported through "ARM
processor error section". But it is not suitable. Because l3tag or l3data
doesn't belong to any single CPU core. So we change it to use OEM format2.

[PATCH rasdaemon 2/2] rasdaemon: fix the issue that non standard decoder can't work in pthread way

[Xiaofei Tan]

The non standard decoding functions are registered in app init process
through __attribute__((constructor)), and unregistered in app exit process
through __attribute__((destructor)). We don't need to unregister them
in any other steps. This patch removes these unnecessary unregister calls.

Fixes: 78a21c1e9770 ("rasdaemon: add closure and cleanups for the database")
