[0/2] ARM: zynq: smp improvements

Message

Luis Araneda Aug. 6, 2019, 3:07 a.m. UTC

This series adds support for kernel compiled in Thumb mode
and fixes a kernel panic on smp bring-up when FORTIFY_SOURCE
is enabled.

The series started with the second patch as an RFC, and
the first patch were suggested on the review to complement
the fix.

The changes were run-tested on a Digilent Zybo Z7 board

This is not the correct way to submit patches for inclusion in the
stable kernel tree.  Please read:
    https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html
for how to do this properly.
