== Summary ==


Thank you for submitting this patch series to OpenEmbedded Core. This is
an automated response. Several tests have been executed on the proposed
series by patchtest resulting in the following failures:



* Issue             Series does not apply on top of target branch [test_series_merge_on_head] 
  Suggested fix    Rebase your series on top of targeted branch
  Targeted branch  master (currently at b30153a157)



If you believe any of these test results are incorrect, please reply to the
mailing list (openembedded-core@lists.openembedded.org) raising your concerns.
Otherwise we would appreciate you correcting the issues and submitting a new
version of the patchset if applicable. Please ensure you add/increment the
version number when sending the new version (i.e. [PATCH] -> [PATCH v2] ->
[PATCH v3] -> ...).

Would this be the cause of glibc failing to build like this on PPC?

read-only segment has dynamic relocations.

The previous glibc run was all green, added this patch and it fails.

yes, I think we need to enable this option only for x86/x86_64/aarch64
since they alone support static PIE and may be we should limit this
to only with security_flags are enabled.
