Retguard will start using sections named ".openbsd.randomdata.retguard.*"
and not just ".openbsd.randomdata.retguard". 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.

sparc64 kernel still lacks a true RODATA segment. However we can make
the SSP read-only by moving the randomdata section into RX text, rather
than leaving it in RW data.

Add a new ELF segment .openbsd.bootdata to the sparc64 kernel.
This can be used to pass boot parameters to the kernel which can't be passed
safely via the Open Firmware interface, such as softraid volume IDs and keys.
The kernel already reads the arguments if available but ofwboot won't provide
them until further changes are committed there.
With support from deraadt, kettenis and matthew.

Make sure the PT_OPENBSD_RANDOMIZE program header actually covers the data
we want to initialize with randomness. It covered exactly nothing before!

Back out the previous commit; rodata gets merged with text by the linker.
Having a seperate rodata segment won't work anyway without significant pmap
changes.

Require an explicit PT_OPENBSD_RANDOMIZE program header in the kernel linker
script (note that the amd64 linker script is currently not used).
Discussed with deraadt@

Moving the .data section causes problems on some machines (blade100, tadpole).
Move it back and add a linker script to convince the linker that it shouldn't
merge .text and .data.
