Accept both in the kernel ldscripts so that they're placed together between the __retguard_{start,end} symbols. Similarly, match not just ".openbsd.randomdata" but also ".openbsd.randomdata.*" to pick up other random (pun intended) items. While here, stub in those retguard bits into all the ldscripts. ok deraadt@ Rework and cleanup the linker script for armv7.

In addition the linker script is now easily diffable to arm64 and we also stop mapping some unnecessary space before the kernel.

Turns out that since we have .rodata in the text segment, it's very easily possible that etext remains unaligned. Work around this by word-aligning etext. The next step is to split .rodata out of the text segment. ok deraadt@ Put the ldscript parts into a single file instead of storing it as head 2018-02-10T06:52:47Z patrick patrick@openbsd.org 2018-02-10T06:52:47Z urn:sha1:69e72f4e91bc3b4aa05108ecd763078497c7d584 and tail and cat(1) it together. It was maybe needed when ports needed different contents, but now it's just a headache. ok deraadt@
