commit e2aa765c4eb9bbcdd3046744e6f73050d1175138
category: feature
feature: ARM kaslr support
bugzilla: 47952
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/ardb/linux.git/commit/?h=arm-kaslr-latest&id=e2aa765c4eb9bbcdd3046744e6f73050d1175138



-------------------------------------------------

This replaces a few copies of the open coded calculations of the
physical address of 'pen_release' in the secondary startup code
of a couple of platforms. This ensures these quantities are invariant
under runtime relocation.
