[9] RFR(S): 8139906: assert(src->section_index_of(target) == CodeBuffer::SECT_NONE) failed: sanity

[Tobias Hartmann]

Hi,

please review the following patch:
https://bugs.openjdk.java.net/browse/JDK-8139906
http://cr.openjdk.java.net/~thartmann/8139906/webrev.00/

On ARM, the card table address used in the g1_post_barrier_slow stub should not be marked as relocatable (similar to what we do on x86 [1]). This was fixed on ARM before but the fix was removed by another change (see comments in the bug).

Tested with failing test and RBT (running).

Thanks,
Tobias
