I tried to upgrade my kernel from 1.6L to current and found that the
kernel will panic very early on startup.  After some staring at the
ddb I think that the problem is that link_set_* sections are linked
incorrectly.

When kernel is linked, ld issues warnings that there are no suitable
memory region for link_set_* sections and put them at 0x0.  This
happens because sys/arch/hpcsh/conf/shl-elf.x defines memory region
"ram" and explicitly places output .text and .data sections into that
region.

But link_set_* sections are not mentioned in the script and when ld
copies those sections from its input to output it doesn't consider
"ram" region as suitable for those sections.

I fixed the problem with adding (rwx) attributes to the "ram" section.
The resulting kernel boots fine.  I'm not sure if it's a proper fixm
though.  Can someone with more ld clue look into this?  Jason?

SY, Uwe
