Subject: [PATCH v4 9/9] powerpc/Kconfig: Enable STRICT_KERNEL_RWX

From: Balbir Singh <[email-masked]>
Date: Tue, 27 Jun 2017 17:49:03 +1000

We have the basic support in the form of patching R/O
text sections, linker scripts for extending alignment
of text data. We've also got mark_rodata_ro()

NOTE: There is a temporary work-around for disabling
STRICT_KERNEL_RWX if CONFIG_HIBERNATION is enabled
