Hi Mark, Alex
There is just one big.LITTLE MP patch for LSK this month. As you
probably saw [1] a second patch was triggering a (probably pre-existing)
problem and needs more time to investigate. So can you pull the other
patch into LSK? Thanks...
The following changes since commit d1df056f9e6dd9707037ed74621e170dfa8f4c52:

commit 6fffb5b47ea1a0f1267b5a218cdea2057cffc1aa
The value of ESR has been stored into x1, and should be directly pass to
do_sp_pc_abort function, "MOV x1, x25" is an extra operation and do_sp_pc_abort
will get the wrong value of ESR.
This patch is just confirmed by Catalin.
